type RuleGroupName

string

param RuleGroupName

[REQUIRED]

The descriptive name of the rule group. You can't change the name of a rule group after you create it.

type RuleGroup

dict

param RuleGroup

An object that defines the rule group rules.

Note

You must provide either this rule group setting or a Rules setting, but not both.

• RuleVariables (dict) --

  Settings that are available for use in the rules in the rule group. You can only use these for stateful rule groups.

  • IPSets (dict) --

    A list of IP addresses and address ranges, in CIDR notation.

    • (string) --

      • (dict) --

        A list of IP addresses and address ranges, in CIDR notation. This is part of a RuleVariables .

        • Definition (list) -- [REQUIRED]

          The list of IP addresses and address ranges, in CIDR notation.

          • (string) --

  • PortSets (dict) --

    A list of port ranges.

    • (string) --

      • (dict) --

        A set of port ranges for use in the rules in a rule group.

        • Definition (list) --

          The set of port ranges.

          • (string) --

• RulesSource (dict) -- [REQUIRED]

  The stateful rules or stateless rules for the rule group.

  • RulesString (string) --

    Stateful inspection criteria, provided in Suricata compatible intrusion prevention system (IPS) rules. Suricata is an open-source network IPS that includes a standard rule-based language for network traffic inspection.

    These rules contain the inspection criteria and the action to take for traffic that matches the criteria, so this type of rule group doesn't have a separate action setting.

    You can provide the rules from a file that you've stored in an Amazon S3 bucket, or by providing the rules in a Suricata rules string. To import from Amazon S3, provide the fully qualified name of the file that contains the rules definitions. To provide a Suricata rule string, provide the complete, Suricata compatible rule.

  • RulesSourceList (dict) --

    Stateful inspection criteria for a domain list rule group.

    • Targets (list) -- [REQUIRED]

      The domains that you want to inspect for in your traffic flows. To provide multiple domains, separate them with commas.

      • (string) --

    • TargetTypes (list) -- [REQUIRED]

      • (string) --

    • GeneratedRulesType (string) -- [REQUIRED]

      Whether you want to allow or deny access to the domains in your target list.

  • StatefulRules (list) --

    The 5-tuple stateful inspection criteria. This contains an array of individual 5-tuple stateful rules to be used together in a stateful rule group.

    • (dict) --

      A single 5-tuple stateful rule, for use in a stateful rule group.

      • Action (string) -- [REQUIRED]

        Defines what Network Firewall should do with the packets in a traffic flow when the flow matches the stateful rule criteria. For all actions, Network Firewall performs the specified action and discontinues stateful inspection of the traffic flow.

        The actions for a stateful rule are defined as follows:

        • PASS - Permits the packets to go to the intended destination.

        • DROP - Blocks the packets from going to the intended destination and sends an alert log message, if alert logging is configured in the Firewall LoggingConfiguration .

        • ALERT - Permits the packets to go to the intended destination and sends an alert log message, if alert logging is configured in the Firewall LoggingConfiguration . You can use this action to test a rule that you intend to use to drop traffic. You can enable the rule with ALERT action, verify in the logs that the rule is filtering as you want, then change the action to DROP .

      • Header (dict) -- [REQUIRED]

        The stateful 5-tuple inspection criteria for this rule, used to inspect traffic flows.

        • Protocol (string) -- [REQUIRED]

          For more information about CIDR notation, see the Wikipedia entry Classless Inter-Domain Routing .

        • SourcePort (string) -- [REQUIRED]

          The source port to inspect for. You can specify an individual port, for example 1994 and you can specify a port range, for example 1990-1994 . To match with any port, specify ANY .

        • Direction (string) -- [REQUIRED]

          The direction of traffic flow to inspect. If set to ANY , the inspection matches bidirectional traffic, both from the source to the destination and from the destination to the source. If set to FORWARD , the inspection only matches traffic going from the source to the destination.

            Note

            Network Firewall only forwards a packet for stateful rule inspection if you specify aws:forward_to_sfe for a rule that the packet matches, or if the packet doesn't match any stateless rule and you specify aws:forward_to_sfe for the StatelessDefaultActions setting for the FirewallPolicy .

            For every rule, you must specify exactly one of the following standard actions.

            • aws:pass - Discontinues all inspection of the packet and permits it to go to its intended destination.

            • aws:drop - Discontinues all inspection of the packet and blocks it from going to its intended destination.

            • aws:forward_to_sfe - Discontinues stateless inspection of the packet and forwards it to the stateful rule engine for inspection.

            Additionally, you can specify a custom action. To do this, you define a custom action by name and type, then provide the name you've assigned to the action in this Actions setting. For information about the options, see CustomAction .

            To provide more than one action in this setting, separate the settings with a comma. For example, if you have a custom PublishMetrics action that you've named MyMetricsAction , then you could specify the standard action aws:pass and the custom action with [“aws:pass”, “MyMetricsAction”] .

            • (string) --

        • Priority (integer) -- [REQUIRED]

          A setting that indicates the order in which to run this rule relative to all of the rules that are defined for a stateless rule group. Network Firewall evaluates the rules in a rule group starting with the lowest priority setting. You must ensure that the priority settings are unique for the rule group.

          Each stateless rule group uses exactly one StatelessRulesAndCustomActions object, and each StatelessRulesAndCustomActions contains exactly one StatelessRules object. To ensure unique priority settings for your rule groups, set unique priorities for the stateless rules that you define inside any single StatelessRules object.

          You can change the priority settings of your rules at any time. To make it easier to insert rules later, number them so there's a wide range in between, for example use 100, 200, and so on.

    • CustomActions (list) --

      Defines an array of individual custom action definitions that are available for use by the stateless rules in this StatelessRulesAndCustomActions specification. You name each custom action that you define, and then you can use it by name in your StatelessRule RuleDefinition Actions specification.

      • (dict) --

        An optional, non-standard action to use for stateless packet handling. You can define this in addition to the standard action that you must specify.

        You define and name the custom actions that you want to be able to use, and then you reference them by name in your actions settings.

        You can use custom actions in the following places:

        • In a rule group's StatelessRulesAndCustomActions specification. The custom actions are available for use by name inside the StatelessRulesAndCustomActions where you define them. You can use them for your stateless rule actions to specify what to do with a packet that matches the rule's match attributes.

        • In a FirewallPolicy specification, in StatelessCustomActions . The custom actions are available for use inside the policy where you define them. You can use them for the policy's default stateless actions settings to specify what to do with packets that don't match any of the policy's stateless rules.

        • ActionName (string) -- [REQUIRED]

          The descriptive name of the custom action. You can't change the name of a custom action after you create it.

        • ActionDefinition (dict) -- [REQUIRED]

          The custom action associated with the action name.

          • PublishMetricAction (dict) --

            Stateless inspection criteria that publishes the specified metrics to Amazon CloudWatch for the matching packet. This setting defines a CloudWatch dimension value to be published.

            You can pair this custom action with any of the standard stateless rule actions. For example, you could pair this in a rule action with the standard action that forwards the packet for stateful inspection. Then, when a packet matches the rule, Network Firewall publishes metrics for the packet and forwards it.

            • Dimensions (list) -- [REQUIRED]

              • (dict) --

                The value to use in an Amazon CloudWatch custom metric dimension. This is used in the PublishMetrics CustomAction . A CloudWatch custom metric dimension is a name/value pair that's part of the identity of a metric.

                AWS Network Firewall sets the dimension name to CustomAction and you provide the dimension value.

                For more information about CloudWatch custom metric dimensions, see Publishing Custom Metrics in the Amazon CloudWatch User Guide .

                • Value (string) -- [REQUIRED]

                  The value to use in the custom metric dimension.

type Rules

string

param Rules

The name of a file containing stateful rule group rules specifications in Suricata flat format, with one rule per line. Use this to import your existing Suricata compatible rule groups.

Note

You must provide either this rules setting or a populated RuleGroup setting, but not both.

You can provide your rule group specification in a file through this setting when you create or update your rule group. The call response returns a RuleGroup object that Network Firewall has populated from your file. Network Firewall uses the file contents to populate the rule group rules, but does not maintain a reference to the file or use the file in any way after performing the create or update. If you call DescribeRuleGroup to retrieve the rule group, Network Firewall returns rules settings inside a RuleGroup object.

type Type

string

param Type

[REQUIRED]

Indicates whether the rule group is stateless or stateful. If the rule group is stateless, it contains stateless rules. If it is stateful, it contains stateful rules.

type Description

string

param Description

A description of the rule group.

type Capacity

integer

param Capacity

[REQUIRED]

The maximum operating resources that this rule group can use. Rule group capacity is fixed at creation. When you update a rule group, you are limited to this capacity. When you reference a rule group from a firewall policy, Network Firewall reserves this capacity for the rule group.

You can retrieve the capacity that would be required for a rule group before you create the rule group by calling CreateRuleGroup with DryRun set to TRUE .

Note

You can't change or exceed this capacity when you update the rule group, so leave room for your rule group to grow.

Capacity for a stateless rule group

For a stateless rule group, the capacity required is the sum of the capacity requirements of the individual rules that you expect to have in the rule group.

To calculate the capacity requirement of a single rule, multiply the capacity requirement values of each of the rule's match settings:

• A match setting with no criteria specified has a value of 1.

• A match setting with Any specified has a value of 1.

• All other match settings have a value equal to the number of elements provided in the setting. For example, a protocol setting ["UDP"] and a source setting ["10.0.0.0/24"] each have a value of 1. A protocol setting ["UDP","TCP"] has a value of 2. A source setting ["10.0.0.0/24","10.0.0.1/24","10.0.0.2/24"] has a value of 3.

A rule with no criteria specified in any of its match settings has a capacity requirement of 1. A rule with protocol setting ["UDP","TCP"], source setting ["10.0.0.0/24","10.0.0.1/24","10.0.0.2/24"], and a single specification or no specification for each of the other match settings has a capacity requirement of 6.

Capacity for a stateful rule group

For a stateful rule group, the minimum capacity required is the number of individual rules that you expect to have in the rule group.

type Tags

list

param Tags

The key:value pairs to associate with the resource.

• (dict) --

  A key:value pair associated with an AWS resource. The key:value pair can be anything you define. Typically, the tag key represents a category (such as "environment") and the tag value represents a specific value within that category (such as "test," "development," or "production"). You can add up to 50 tags to each AWS resource.

  • Key (string) -- [REQUIRED]

    The part of the key:value pair that defines a tag. You can use a tag key to describe a category of information, such as "customer." Tag keys are case-sensitive.

  • Value (string) -- [REQUIRED]

    The part of the key:value pair that defines a tag. You can use a tag value to describe a specific value within a category, such as "companyA" or "companyB." Tag values are case-sensitive.

type DryRun

boolean

param DryRun

Indicates whether you want Network Firewall to just check the validity of the request, rather than run the request.

If set to TRUE , Network Firewall checks whether the request can run successfully, but doesn't actually make the requested changes. The call returns the value that the request would return if you ran it with dry run set to FALSE , but doesn't make additions or changes to your resources. This option allows you to make sure that you have the required permissions to run the request and that your request parameters are valid.

If set to FALSE , Network Firewall makes the requested changes to your resources.

      The unique identifier of the VPC where the firewall is in use.

    • SubnetMappings (list) --

      The public subnets that Network Firewall is using for the firewall. Each subnet must belong to a different Availability Zone.

      • (dict) --

        The ID for a subnet that you want to associate with the firewall. This is used with CreateFirewall and AssociateSubnets . AWS Network Firewall creates an instance of the associated firewall in each subnet that you specify, to filter traffic in the subnet's Availability Zone.

        • SubnetId (string) --

          The unique identifier for the subnet.

    • DeleteProtection (boolean) --

      A flag indicating whether it is possible to delete the firewall. A setting of TRUE indicates that the firewall is protected against deletion.

    Detailed information about the current status of a Firewall . You can retrieve this for a firewall by calling DescribeFirewall and providing the firewall name and ARN.

    • Status (string) --

      The readiness of the configured firewall to handle network traffic across all of the Availability Zones where you've configured it. This setting is READY only when the ConfigurationSyncStateSummary value is IN_SYNC and the Attachment Status values for all of the configured subnets are READY .

    • ConfigurationSyncStateSummary (string) --

      The configuration sync state for the firewall. This summarizes the sync states reported in the Config settings for all of the Availability Zones where you have configured the firewall.

      When you create a firewall or update its configuration, for example by adding a rule group to its firewall policy, Network Firewall distributes the configuration changes to all zones where the firewall is in use. This summary indicates whether the configuration changes have been applied everywhere.

      This status must be IN_SYNC for the firewall to be ready for use, but it doesn't indicate that the firewall is ready. The Status setting indicates firewall readiness.

    • SyncStates (dict) --

      The subnets that you've configured for use by the Network Firewall firewall. This contains one array element per Availability Zone where you've configured a subnet. These objects provide details of the information that is summarized in the ConfigurationSyncStateSummary and Status , broken down by zone and configuration object.

      • (string) --

        • (dict) --

          The status of the firewall endpoint and firewall policy configuration for a single VPC subnet.

          For each VPC subnet that you associate with a firewall, AWS Network Firewall does the following:

          • Instantiates a firewall endpoint in the subnet, ready to take traffic.

          • Configures the endpoint with the current firewall policy settings, to provide the filtering behavior for the endpoint.

          When you update a firewall, for example to add a subnet association or change a rule group in the firewall policy, the affected sync states reflect out-of-sync or not ready status until the changes are complete.

          • Attachment (dict) --

            The attachment status of the firewall's association with a single VPC subnet. For each configured subnet, Network Firewall creates the attachment by instantiating the firewall endpoint in the subnet so that it's ready to take traffic. This is part of the FirewallStatus .

            • SubnetId (string) --

              The unique identifier of the subnet that you've specified to be used for a firewall endpoint.

            • EndpointId (string) --

              The identifier of the firewall endpoint that Network Firewall has instantiated in the subnet. You use this to identify the firewall endpoint in the VPC route tables, when you redirect the VPC traffic through the endpoint.

            • Status (string) --

              The current status of the firewall endpoint in the subnet. This value reflects both the instantiation of the endpoint in the VPC subnet and the sync states that are reported in the Config settings. When this value is READY , the endpoint is available and configured properly to handle network traffic. When the endpoint isn't available for traffic, this value will reflect its state, for example CREATING , DELETING , or FAILED .

          • Config (dict) --

            The configuration status of the firewall endpoint in a single VPC subnet. Network Firewall provides each endpoint with the rules that are configured in the firewall policy. Each time you add a subnet or modify the associated firewall policy, Network Firewall synchronizes the rules in the endpoint, so it can properly filter network traffic. This is part of the FirewallStatus .

            • (string) --

              • (dict) --

                • SyncStatus (string) --

Retrieves the metadata for the firewalls that you have defined. If you provide VPC identifiers in your request, this returns only the firewalls for those VPCs.

Depending on your setting for max results and the number of firewalls, a single call might not return the full list.

type FirewallPolicyName

string

param FirewallPolicyName

[REQUIRED]

The descriptive name of the firewall policy. You can't change the name of a firewall policy after you create it.

type FirewallPolicy

dict

param FirewallPolicy

[REQUIRED]

The rule groups and policy actions to use in the firewall policy.

• StatelessRuleGroupReferences (list) --

  References to the stateless rule groups that are used in the policy. These define the matching criteria in stateless rules.

  • (dict) --

    Identifier for a single stateless rule group, used in a firewall policy to refer to the rule group.

    • ResourceArn (string) -- [REQUIRED]

      The Amazon Resource Name (ARN) of the stateless rule group.

    • Priority (integer) -- [REQUIRED]

      An integer setting that indicates the order in which to run the stateless rule groups in a single FirewallPolicy . Network Firewall applies each stateless rule group to a packet starting with the group that has the lowest priority setting. You must ensure that the priority settings are unique within each policy.

• StatelessDefaultActions (list) -- [REQUIRED]

  The actions to take on a packet if it doesn't match any of the stateless rules in the policy. If you want non-matching packets to be forwarded for stateful inspection, specify aws:forward_to_sfe .

  You must specify one of the standard actions: aws:pass , aws:drop , or aws:forward_to_sfe . In addition, you can specify custom actions that are compatible with your standard section choice.

  For example, you could specify ["aws:pass"] or you could specify ["aws:pass", “customActionName”] . For information about compatibility, see the custom action descriptions under CustomAction .

  • (string) --

• StatelessFragmentDefaultActions (list) -- [REQUIRED]

  The actions to take on a fragmented packet if it doesn't match any of the stateless rules in the policy. If you want non-matching fragmented packets to be forwarded for stateful inspection, specify aws:forward_to_sfe .

  You must specify one of the standard actions: aws:pass , aws:drop , or aws:forward_to_sfe . In addition, you can specify custom actions that are compatible with your standard section choice.

  For example, you could specify ["aws:pass"] or you could specify ["aws:pass", “customActionName”] . For information about compatibility, see the custom action descriptions under CustomAction .

  • (string) --

• StatelessCustomActions (list) --

  The custom action definitions that are available for use in the firewall policy's StatelessDefaultActions setting. You name each custom action that you define, and then you can use it by name in your default actions specifications.

  • (dict) --

    An optional, non-standard action to use for stateless packet handling. You can define this in addition to the standard action that you must specify.

    You define and name the custom actions that you want to be able to use, and then you reference them by name in your actions settings.

    You can use custom actions in the following places:

    • In a rule group's StatelessRulesAndCustomActions specification. The custom actions are available for use by name inside the StatelessRulesAndCustomActions where you define them. You can use them for your stateless rule actions to specify what to do with a packet that matches the rule's match attributes.

    • In a FirewallPolicy specification, in StatelessCustomActions . The custom actions are available for use inside the policy where you define them. You can use them for the policy's default stateless actions settings to specify what to do with packets that don't match any of the policy's stateless rules.

    • ActionName (string) -- [REQUIRED]

      The descriptive name of the custom action. You can't change the name of a custom action after you create it.

    • ActionDefinition (dict) -- [REQUIRED]

      The custom action associated with the action name.

      • PublishMetricAction (dict) --

        Stateless inspection criteria that publishes the specified metrics to Amazon CloudWatch for the matching packet. This setting defines a CloudWatch dimension value to be published.

        You can pair this custom action with any of the standard stateless rule actions. For example, you could pair this in a rule action with the standard action that forwards the packet for stateful inspection. Then, when a packet matches the rule, Network Firewall publishes metrics for the packet and forwards it.

        • Dimensions (list) -- [REQUIRED]

          • (dict) --

            The value to use in an Amazon CloudWatch custom metric dimension. This is used in the PublishMetrics CustomAction . A CloudWatch custom metric dimension is a name/value pair that's part of the identity of a metric.

            AWS Network Firewall sets the dimension name to CustomAction and you provide the dimension value.

            For more information about CloudWatch custom metric dimensions, see Publishing Custom Metrics in the Amazon CloudWatch User Guide .

            • Value (string) -- [REQUIRED]

              The value to use in the custom metric dimension.

• StatefulRuleGroupReferences (list) --

  References to the stateless rule groups that are used in the policy. These define the inspection criteria in stateful rules.

  • (dict) --

    Identifier for a single stateful rule group, used in a firewall policy to refer to a rule group.

    • ResourceArn (string) -- [REQUIRED]

      The Amazon Resource Name (ARN) of the stateful rule group.

type Description

string

param Description

A description of the firewall policy.

type Tags

list

param Tags

The key:value pairs to associate with the resource.

• (dict) --

  A key:value pair associated with an AWS resource. The key:value pair can be anything you define. Typically, the tag key represents a category (such as "environment") and the tag value represents a specific value within that category (such as "test," "development," or "production"). You can add up to 50 tags to each AWS resource.

  • Key (string) -- [REQUIRED]

    The part of the key:value pair that defines a tag. You can use a tag key to describe a category of information, such as "customer." Tag keys are case-sensitive.

  • Value (string) -- [REQUIRED]

    The part of the key:value pair that defines a tag. You can use a tag value to describe a specific value within a category, such as "companyA" or "companyB." Tag values are case-sensitive.

type DryRun

boolean

param DryRun

Indicates whether you want Network Firewall to just check the validity of the request, rather than run the request.

If set to TRUE , Network Firewall checks whether the request can run successfully, but doesn't actually make the requested changes. The call returns the value that the request would return if you ran it with dry run set to FALSE , but doesn't make additions or changes to your resources. This option allows you to make sure that you have the required permissions to run the request and that your request parameters are valid.

If set to FALSE , Network Firewall makes the requested changes to your resources.

  • FirewallPolicyChangeProtection (boolean) --

    A setting indicating whether the firewall is protected against a change to the firewall policy association. Use this setting to protect against accidentally modifying the firewall policy for a firewall that is in use. When you create a firewall, the operation initializes this setting to TRUE .

Modifies the flag, DeleteProtection , which indicates whether it is possible to delete the firewall. If the flag is set to TRUE , the firewall is protected against deletion. This setting helps protect against accidentally deleting a firewall that's in use.

type UpdateToken

string

param UpdateToken

An optional token that you can use for optimistic locking. Network Firewall returns a token to your requests that access the firewall. The token marks the state of the firewall resource at the time of the request.

To make an unconditional change to the firewall, omit the token in your update request. Without the token, Network Firewall performs your updates regardless of whether the firewall has changed since you last retrieved it.

To make a conditional change to the firewall, provide the token in your update request. Network Firewall uses the token to ensure that the firewall hasn't changed since you last retrieved it. If it has changed, the operation fails with an InvalidTokenException . If this happens, retrieve the firewall again to get a current copy of it with a new token. Reapply your changes as needed, then try the operation again using the new token.

type FirewallArn

string

param FirewallArn

The Amazon Resource Name (ARN) of the firewall.

You must specify the ARN or the name, and you can specify both.

type UpdateToken

string

param UpdateToken

[REQUIRED]

A token used for optimistic locking. Network Firewall returns a token to your requests that access the rule group. The token marks the state of the rule group resource at the time of the request.

To make changes to the rule group, you provide the token in your request. Network Firewall uses the token to ensure that the rule group hasn't changed since you last retrieved it. If it has changed, the operation fails with an InvalidTokenException . If this happens, retrieve the rule group again to get a current copy of it with a current token. Reapply your changes as needed, then try the operation again using the new token.

    These rules contain the inspection criteria and the action to take for traffic that matches the criteria, so this type of rule group doesn't have a separate action setting.

    You can provide the rules from a file that you've stored in an Amazon S3 bucket, or by providing the rules in a Suricata rules string. To import from Amazon S3, provide the fully qualified name of the file that contains the rules definitions. To provide a Suricata rule string, provide the complete, Suricata compatible rule.

        • PASS - Permits the packets to go to the intended destination.

        • DROP - Blocks the packets from going to the intended destination and sends an alert log message, if alert logging is configured in the Firewall LoggingConfiguration .

        • ALERT - Permits the packets to go to the intended destination and sends an alert log message, if alert logging is configured in the Firewall LoggingConfiguration . You can use this action to test a rule that you intend to use to drop traffic. You can enable the rule with ALERT action, verify in the logs that the rule is filtering as you want, then change the action to DROP .

            • DestinationPorts (list) --

              The destination ports to inspect for. If not specified, this matches with any destination port. This setting is only used for protocols 6 (TCP) and 17 (UDP).

              You can specify individual ports, for example 1994 and you can specify port ranges, for example 1990-1994 .

            • Protocols (list) --

              The protocols to inspect for, specified using each protocol's assigned internet protocol number (IANA). If not specified, this matches with any protocol.

              • (integer) --

            • TCPFlags (list) --

              The TCP flags and masks to inspect for. If not specified, this matches with any settings. This setting is only used for protocol 6 (TCP).

              • (dict) --

                TCP flags and masks to inspect packets for, used in stateless rules MatchAttributes settings.

                • Flags (list) -- [REQUIRED]

                  Used in conjunction with the Masks setting to define the flags that must be set and flags that must not be set in order for the packet to match. This setting can only specify values that are also specified in the Masks setting.

                  For the flags that are specified in the masks setting, the following must be true for the packet to match:

                  • The ones that are set in this flags setting must be set in the packet.

                  • The ones that are not set in this flags setting must also not be set in the packet.

                  • (string) --

                • Masks (list) --

                  The set of flags to consider in the inspection. To inspect all flags in the valid values list, leave this with no setting.

                  • (string) --

          • Actions (list) -- [REQUIRED]

            The actions to take on a packet that matches one of the stateless rule definition's match attributes. You must specify a standard action and you can add custom actions.

            Note

            Network Firewall only forwards a packet for stateful rule inspection if you specify aws:forward_to_sfe for a rule that the packet matches, or if the packet doesn't match any stateless rule and you specify aws:forward_to_sfe for the StatelessDefaultActions setting for the FirewallPolicy .

            For every rule, you must specify exactly one of the following standard actions.

            • aws:pass - Discontinues all inspection of the packet and permits it to go to its intended destination.

            • aws:drop - Discontinues all inspection of the packet and blocks it from going to its intended destination.

            • aws:forward_to_sfe - Discontinues stateless inspection of the packet and forwards it to the stateful rule engine for inspection.

            Additionally, you can specify a custom action. To do this, you define a custom action by name and type, then provide the name you've assigned to the action in this Actions setting. For information about the options, see CustomAction .

            To provide more than one action in this setting, separate the settings with a comma. For example, if you have a custom PublishMetrics action that you've named MyMetricsAction , then you could specify the standard action aws:pass and the custom action with [“aws:pass”, “MyMetricsAction”] .

            • (string) --

        • Priority (integer) -- [REQUIRED]

          A setting that indicates the order in which to run this rule relative to all of the rules that are defined for a stateless rule group. Network Firewall evaluates the rules in a rule group starting with the lowest priority setting. You must ensure that the priority settings are unique for the rule group.

          Each stateless rule group uses exactly one StatelessRulesAndCustomActions object, and each StatelessRulesAndCustomActions contains exactly one StatelessRules object. To ensure unique priority settings for your rule groups, set unique priorities for the stateless rules that you define inside any single StatelessRules object.

          You can change the priority settings of your rules at any time. To make it easier to insert rules later, number them so there's a wide range in between, for example use 100, 200, and so on.

    • CustomActions (list) --

      Defines an array of individual custom action definitions that are available for use by the stateless rules in this StatelessRulesAndCustomActions specification. You name each custom action that you define, and then you can use it by name in your StatelessRule RuleDefinition Actions specification.

      • (dict) --

        An optional, non-standard action to use for stateless packet handling. You can define this in addition to the standard action that you must specify.

        You define and name the custom actions that you want to be able to use, and then you reference them by name in your actions settings.

        You can use custom actions in the following places:

        • In a rule group's StatelessRulesAndCustomActions specification. The custom actions are available for use by name inside the StatelessRulesAndCustomActions where you define them. You can use them for your stateless rule actions to specify what to do with a packet that matches the rule's match attributes.

        • In a FirewallPolicy specification, in StatelessCustomActions . The custom actions are available for use inside the policy where you define them. You can use them for the policy's default stateless actions settings to specify what to do with packets that don't match any of the policy's stateless rules.

        • ActionName (string) -- [REQUIRED]

          The descriptive name of the custom action. You can't change the name of a custom action after you create it.

        • ActionDefinition (dict) -- [REQUIRED]

          The custom action associated with the action name.

          • PublishMetricAction (dict) --

            Stateless inspection criteria that publishes the specified metrics to Amazon CloudWatch for the matching packet. This setting defines a CloudWatch dimension value to be published.

            You can pair this custom action with any of the standard stateless rule actions. For example, you could pair this in a rule action with the standard action that forwards the packet for stateful inspection. Then, when a packet matches the rule, Network Firewall publishes metrics for the packet and forwards it.

            • Dimensions (list) -- [REQUIRED]

              • (dict) --

                The value to use in an Amazon CloudWatch custom metric dimension. This is used in the PublishMetrics CustomAction . A CloudWatch custom metric dimension is a name/value pair that's part of the identity of a metric.

                AWS Network Firewall sets the dimension name to CustomAction and you provide the dimension value.

                For more information about CloudWatch custom metric dimensions, see Publishing Custom Metrics in the Amazon CloudWatch User Guide .

                • Value (string) -- [REQUIRED]

                  The value to use in the custom metric dimension.

type Rules

string

param Rules

The name of a file containing stateful rule group rules specifications in Suricata flat format, with one rule per line. Use this to import your existing Suricata compatible rule groups.

Note

You must provide either this rules setting or a populated RuleGroup setting, but not both.

You can provide your rule group specification in a file through this setting when you create or update your rule group. The call response returns a RuleGroup object that Network Firewall has populated from your file. Network Firewall uses the file contents to populate the rule group rules, but does not maintain a reference to the file or use the file in any way after performing the create or update. If you call DescribeRuleGroup to retrieve the rule group, Network Firewall returns rules settings inside a RuleGroup object.

type Type

string

param Type

Indicates whether the rule group is stateless or stateful. If the rule group is stateless, it contains stateless rules. If it is stateful, it contains stateful rules.

Note

This setting is required for requests that do not include the RuleGroupARN .

type Description

string

param Description

A description of the rule group.

type DryRun

boolean

param DryRun

Indicates whether you want Network Firewall to just check the validity of the request, rather than run the request.

If set to TRUE , Network Firewall checks whether the request can run successfully, but doesn't actually make the requested changes. The call returns the value that the request would return if you ran it with dry run set to FALSE , but doesn't make additions or changes to your resources. This option allows you to make sure that you have the required permissions to run the request and that your request parameters are valid.

If set to FALSE , Network Firewall makes the requested changes to your resources.

Response Structure

• (dict) --

  • UpdateToken (string) --

    A token used for optimistic locking. Network Firewall returns a token to your requests that access the firewall policy. The token marks the state of the policy resource at the time of the request.

    To make changes to the policy, you provide the token in your request. Network Firewall uses the token to ensure that the policy hasn't changed since you last retrieved it. If it has changed, the operation fails with an InvalidTokenException . If this happens, retrieve the firewall policy again to get a current copy of it with current token. Reapply your changes as needed, then try the operation again using the new token.

      The key:value pairs to associate with the resource.

      • (dict) --

        A key:value pair associated with an AWS resource. The key:value pair can be anything you define. Typically, the tag key represents a category (such as "environment") and the tag value represents a specific value within that category (such as "test," "development," or "production"). You can add up to 50 tags to each AWS resource.

        • Key (string) --

          The part of the key:value pair that defines a tag. You can use a tag key to describe a category of information, such as "customer." Tag keys are case-sensitive.

        • Value (string) --

          The part of the key:value pair that defines a tag. You can use a tag value to describe a specific value within a category, such as "companyA" or "companyB." Tag values are case-sensitive.

  • FirewallPolicy (dict) --

    The policy for the specified firewall policy.

    • StatelessRuleGroupReferences (list) --

      References to the stateless rule groups that are used in the policy. These define the matching criteria in stateless rules.

        Identifier for a single stateless rule group, used in a firewall policy to refer to the rule group.

        • ResourceArn (string) --

          The Amazon Resource Name (ARN) of the stateless rule group.

        • Priority (integer) --

          An integer setting that indicates the order in which to run the stateless rule groups in a single FirewallPolicy . Network Firewall applies each stateless rule group to a packet starting with the group that has the lowest priority setting. You must ensure that the priority settings are unique within each policy.

    • StatelessDefaultActions (list) --

      The actions to take on a packet if it doesn't match any of the stateless rules in the policy. If you want non-matching packets to be forwarded for stateful inspection, specify aws:forward_to_sfe .

      You must specify one of the standard actions: aws:pass , aws:drop , or aws:forward_to_sfe . In addition, you can specify custom actions that are compatible with your standard section choice.

      For example, you could specify ["aws:pass"] or you could specify ["aws:pass", “customActionName”] . For information about compatibility, see the custom action descriptions under CustomAction .

      • (string) --

    • StatelessFragmentDefaultActions (list) --

      The actions to take on a fragmented packet if it doesn't match any of the stateless rules in the policy. If you want non-matching fragmented packets to be forwarded for stateful inspection, specify aws:forward_to_sfe .

      You must specify one of the standard actions: aws:pass , aws:drop , or aws:forward_to_sfe . In addition, you can specify custom actions that are compatible with your standard section choice.

      For example, you could specify ["aws:pass"] or you could specify ["aws:pass", “customActionName”] . For information about compatibility, see the custom action descriptions under CustomAction .

      • (string) --

    • StatelessCustomActions (list) --

      The custom action definitions that are available for use in the firewall policy's StatelessDefaultActions setting. You name each custom action that you define, and then you can use it by name in your default actions specifications.

      • (dict) --

        An optional, non-standard action to use for stateless packet handling. You can define this in addition to the standard action that you must specify.

        You define and name the custom actions that you want to be able to use, and then you reference them by name in your actions settings.

        You can use custom actions in the following places:

        • In a rule group's StatelessRulesAndCustomActions specification. The custom actions are available for use by name inside the StatelessRulesAndCustomActions where you define them. You can use them for your stateless rule actions to specify what to do with a packet that matches the rule's match attributes.

        • In a FirewallPolicy specification, in StatelessCustomActions . The custom actions are available for use inside the policy where you define them. You can use them for the policy's default stateless actions settings to specify what to do with packets that don't match any of the policy's stateless rules.

        • ActionName (string) --

          The descriptive name of the custom action. You can't change the name of a custom action after you create it.

          • PublishMetricAction (dict) --

            Stateless inspection criteria that publishes the specified metrics to Amazon CloudWatch for the matching packet. This setting defines a CloudWatch dimension value to be published.

            You can pair this custom action with any of the standard stateless rule actions. For example, you could pair this in a rule action with the standard action that forwards the packet for stateful inspection. Then, when a packet matches the rule, Network Firewall publishes metrics for the packet and forwards it.

            • Dimensions (list) --

              • (dict) --

                The value to use in an Amazon CloudWatch custom metric dimension. This is used in the PublishMetrics CustomAction . A CloudWatch custom metric dimension is a name/value pair that's part of the identity of a metric.

                AWS Network Firewall sets the dimension name to CustomAction and you provide the dimension value.

                For more information about CloudWatch custom metric dimensions, see Publishing Custom Metrics in the Amazon CloudWatch User Guide .

                • Value (string) --

                  The value to use in the custom metric dimension.

    • StatefulRuleGroupReferences (list) --

      References to the stateless rule groups that are used in the policy. These define the inspection criteria in stateful rules.

      • (dict) --

        Identifier for a single stateful rule group, used in a firewall policy to refer to a rule group.

        • ResourceArn (string) --

          The Amazon Resource Name (ARN) of the stateful rule group.

Deletes the specified Firewall and its FirewallStatus . This operation requires the firewall's DeleteProtection flag to be FALSE . You can't revert this operation.

You can check whether a firewall is in use by reviewing the route tables for the Availability Zones where you have firewall subnet mappings. Retrieve the subnet mappings by calling DescribeFirewall . You define and update the route tables through Amazon VPC. As needed, update the route tables for the zones to remove the firewall endpoints. When the route tables no longer use the firewall endpoints, you can remove the firewall safely.

To delete a firewall, remove the delete protection if you need to using UpdateFirewallDeleteProtection , then delete the firewall by calling DeleteFirewall .

    • FirewallName (string) --

      The descriptive name of the firewall. You can't change the name of a firewall after you create it.

    • FirewallArn (string) --

      The Amazon Resource Name (ARN) of the firewall.

    • FirewallPolicyArn (string) --

      The Amazon Resource Name (ARN) of the firewall policy.

      The relationship of firewall to firewall policy is many to one. Each firewall requires one firewall policy association, and you can use the same firewall policy for multiple firewalls.

    • VpcId (string) --

      The unique identifier of the VPC where the firewall is in use.

    • SubnetMappings (list) --

      The public subnets that Network Firewall is using for the firewall. Each subnet must belong to a different Availability Zone.

      • (dict) --

        The ID for a subnet that you want to associate with the firewall. This is used with CreateFirewall and AssociateSubnets . AWS Network Firewall creates an instance of the associated firewall in each subnet that you specify, to filter traffic in the subnet's Availability Zone.

        • SubnetId (string) --

          The unique identifier for the subnet.

    • DeleteProtection (boolean) --

      A flag indicating whether it is possible to delete the firewall. A setting of TRUE indicates that the firewall is protected against deletion. Use this setting to protect against accidentally deleting a firewall that is in use. When you create a firewall, the operation initializes this flag to TRUE .

    • SubnetChangeProtection (boolean) --

      A setting indicating whether the firewall is protected against changes to the subnet associations. Use this setting to protect against accidentally modifying the subnet associations for a firewall that is in use. When you create a firewall, the operation initializes this setting to TRUE .

    • FirewallPolicyChangeProtection (boolean) --

      A setting indicating whether the firewall is protected against a change to the firewall policy association. Use this setting to protect against accidentally modifying the firewall policy for a firewall that is in use. When you create a firewall, the operation initializes this setting to TRUE .

    • Description (string) --

      A description of the firewall.

    • FirewallId (string) --

      The unique identifier for the firewall.

    • Tags (list) --

      • (dict) --

        A key:value pair associated with an AWS resource. The key:value pair can be anything you define. Typically, the tag key represents a category (such as "environment") and the tag value represents a specific value within that category (such as "test," "development," or "production"). You can add up to 50 tags to each AWS resource.

        • Key (string) --

          The part of the key:value pair that defines a tag. You can use a tag key to describe a category of information, such as "customer." Tag keys are case-sensitive.

        • Value (string) --

          The part of the key:value pair that defines a tag. You can use a tag value to describe a specific value within a category, such as "companyA" or "companyB." Tag values are case-sensitive.

  • FirewallStatus (dict) --

    Detailed information about the current status of a Firewall . You can retrieve this for a firewall by calling DescribeFirewall and providing the firewall name and ARN.

    • Status (string) --

      The readiness of the configured firewall to handle network traffic across all of the Availability Zones where you've configured it. This setting is READY only when the ConfigurationSyncStateSummary value is IN_SYNC and the Attachment Status values for all of the configured subnets are READY .

    • ConfigurationSyncStateSummary (string) --

      The configuration sync state for the firewall. This summarizes the sync states reported in the Config settings for all of the Availability Zones where you have configured the firewall.

      When you create a firewall or update its configuration, for example by adding a rule group to its firewall policy, Network Firewall distributes the configuration changes to all zones where the firewall is in use. This summary indicates whether the configuration changes have been applied everywhere.

      This status must be IN_SYNC for the firewall to be ready for use, but it doesn't indicate that the firewall is ready. The Status setting indicates firewall readiness.

    • SyncStates (dict) --

      The subnets that you've configured for use by the Network Firewall firewall. This contains one array element per Availability Zone where you've configured a subnet. These objects provide details of the information that is summarized in the ConfigurationSyncStateSummary and Status , broken down by zone and configuration object.

      • (string) --

        • (dict) --

          The status of the firewall endpoint and firewall policy configuration for a single VPC subnet.

          For each VPC subnet that you associate with a firewall, AWS Network Firewall does the following:

          • Instantiates a firewall endpoint in the subnet, ready to take traffic.

          • Configures the endpoint with the current firewall policy settings, to provide the filtering behavior for the endpoint.

          When you update a firewall, for example to add a subnet association or change a rule group in the firewall policy, the affected sync states reflect out-of-sync or not ready status until the changes are complete.

          • Attachment (dict) --

            The attachment status of the firewall's association with a single VPC subnet. For each configured subnet, Network Firewall creates the attachment by instantiating the firewall endpoint in the subnet so that it's ready to take traffic. This is part of the FirewallStatus .

            • SubnetId (string) --

              The unique identifier of the subnet that you've specified to be used for a firewall endpoint.

            • EndpointId (string) --

              The identifier of the firewall endpoint that Network Firewall has instantiated in the subnet. You use this to identify the firewall endpoint in the VPC route tables, when you redirect the VPC traffic through the endpoint.

            • Status (string) --

              The current status of the firewall endpoint in the subnet. This value reflects both the instantiation of the endpoint in the VPC subnet and the sync states that are reported in the Config settings. When this value is READY , the endpoint is available and configured properly to handle network traffic. When the endpoint isn't available for traffic, this value will reflect its state, for example CREATING , DELETING , or FAILED .

          • Config (dict) --

            The configuration status of the firewall endpoint in a single VPC subnet. Network Firewall provides each endpoint with the rules that are configured in the firewall policy. Each time you add a subnet or modify the associated firewall policy, Network Firewall synchronizes the rules in the endpoint, so it can properly filter network traffic. This is part of the FirewallStatus .

            • (string) --

              • (dict) --

                • SyncStatus (string) --

Creates an AWS Network Firewall Firewall and accompanying FirewallStatus for a VPC.

The firewall defines the configuration settings for an AWS Network Firewall firewall. The settings that you can define at creation include the firewall policy, the subnets in your VPC to use for the firewall endpoints, and any tags that are attached to the firewall AWS resource.

After you create a firewall, you can provide additional settings, like the logging configuration.

To update the settings for a firewall, you use the operations that apply to the settings themselves, for example UpdateLoggingConfiguration , AssociateSubnets , and UpdateFirewallDeleteProtection .

To manage a firewall's tags, use the standard AWS resource tagging operations, ListTagsForResource , TagResource , and UntagResource .

To retrieve information about firewalls, use ListFirewalls and DescribeFirewall .

        • Value (string) --

          The part of the key:value pair that defines a tag. You can use a tag value to describe a specific value within a category, such as "companyA" or "companyB." Tag values are case-sensitive.

  • FirewallStatus (dict) --

    Detailed information about the current status of a Firewall . You can retrieve this for a firewall by calling DescribeFirewall and providing the firewall name and ARN.

    • Status (string) --

      The readiness of the configured firewall to handle network traffic across all of the Availability Zones where you've configured it. This setting is READY only when the ConfigurationSyncStateSummary value is IN_SYNC and the Attachment Status values for all of the configured subnets are READY .

    • ConfigurationSyncStateSummary (string) --

      The configuration sync state for the firewall. This summarizes the sync states reported in the Config settings for all of the Availability Zones where you have configured the firewall.

      When you create a firewall or update its configuration, for example by adding a rule group to its firewall policy, Network Firewall distributes the configuration changes to all zones where the firewall is in use. This summary indicates whether the configuration changes have been applied everywhere.

      This status must be IN_SYNC for the firewall to be ready for use, but it doesn't indicate that the firewall is ready. The Status setting indicates firewall readiness.

    • SyncStates (dict) --

      The subnets that you've configured for use by the Network Firewall firewall. This contains one array element per Availability Zone where you've configured a subnet. These objects provide details of the information that is summarized in the ConfigurationSyncStateSummary and Status , broken down by zone and configuration object.

      • (string) --

        • (dict) --

          The status of the firewall endpoint and firewall policy configuration for a single VPC subnet.

          For each VPC subnet that you associate with a firewall, AWS Network Firewall does the following:

          • Instantiates a firewall endpoint in the subnet, ready to take traffic.

          • Configures the endpoint with the current firewall policy settings, to provide the filtering behavior for the endpoint.

          When you update a firewall, for example to add a subnet association or change a rule group in the firewall policy, the affected sync states reflect out-of-sync or not ready status until the changes are complete.

          • Attachment (dict) --

            The attachment status of the firewall's association with a single VPC subnet. For each configured subnet, Network Firewall creates the attachment by instantiating the firewall endpoint in the subnet so that it's ready to take traffic. This is part of the FirewallStatus .

            • SubnetId (string) --

              The unique identifier of the subnet that you've specified to be used for a firewall endpoint.

            • EndpointId (string) --

              The identifier of the firewall endpoint that Network Firewall has instantiated in the subnet. You use this to identify the firewall endpoint in the VPC route tables, when you redirect the VPC traffic through the endpoint.

            • Status (string) --

              The current status of the firewall endpoint in the subnet. This value reflects both the instantiation of the endpoint in the VPC subnet and the sync states that are reported in the Config settings. When this value is READY , the endpoint is available and configured properly to handle network traffic. When the endpoint isn't available for traffic, this value will reflect its state, for example CREATING , DELETING , or FAILED .

          • Config (dict) --

            The configuration status of the firewall endpoint in a single VPC subnet. Network Firewall provides each endpoint with the rules that are configured in the firewall policy. Each time you add a subnet or modify the associated firewall policy, Network Firewall synchronizes the rules in the endpoint, so it can properly filter network traffic. This is part of the FirewallStatus .

            • (string) --

              • (dict) --

                • SyncStatus (string) --

Response Structure

• (dict) --

  • UpdateToken (string) --

    A token used for optimistic locking. Network Firewall returns a token to your requests that access the rule group. The token marks the state of the rule group resource at the time of the request.

    To make changes to the rule group, you provide the token in your request. Network Firewall uses the token to ensure that the rule group hasn't changed since you last retrieved it. If it has changed, the operation fails with an InvalidTokenException . If this happens, retrieve the rule group again to get a current copy of it with a current token. Reapply your changes as needed, then try the operation again using the new token.

  • RuleGroup (dict) --

    The object that defines the rules in a rule group. This, along with RuleGroupResponse , define the rule group. You can retrieve all objects for a rule group by calling DescribeRuleGroup .

    AWS Network Firewall uses a rule group to inspect and control network traffic. You define stateless rule groups to inspect individual packets and you define stateful rule groups to inspect packets in the context of their traffic flow.

    To use a rule group, you include it by reference in an Network Firewall firewall policy, then you use the policy in a firewall. You can reference a rule group from more than one firewall policy, and you can use a firewall policy in more than one firewall.

    • RuleVariables (dict) --

      Settings that are available for use in the rules in the rule group. You can only use these for stateful rule groups.

              The list of IP addresses and address ranges, in CIDR notation.

              • (string) --

      • PortSets (dict) --

        A list of port ranges.

        • (string) --

          • (dict) --

            A set of port ranges for use in the rules in a rule group.

            • Definition (list) --

              The set of port ranges.

              • (string) --

    • RulesSource (dict) --

      The stateful rules or stateless rules for the rule group.

      • RulesString (string) --

        Stateful inspection criteria, provided in Suricata compatible intrusion prevention system (IPS) rules. Suricata is an open-source network IPS that includes a standard rule-based language for network traffic inspection.

        These rules contain the inspection criteria and the action to take for traffic that matches the criteria, so this type of rule group doesn't have a separate action setting.

        You can provide the rules from a file that you've stored in an Amazon S3 bucket, or by providing the rules in a Suricata rules string. To import from Amazon S3, provide the fully qualified name of the file that contains the rules definitions. To provide a Suricata rule string, provide the complete, Suricata compatible rule.

      • RulesSourceList (dict) --

        Stateful inspection criteria for a domain list rule group.

                      For the flags that are specified in the masks setting, the following must be true for the packet to match:

                      • The ones that are set in this flags setting must be set in the packet.

                      • The ones that are not set in this flags setting must also not be set in the packet.

                      • (string) --

                    • Masks (list) --

                      The set of flags to consider in the inspection. To inspect all flags in the valid values list, leave this with no setting.

                      • (string) --

              • Actions (list) --

                The actions to take on a packet that matches one of the stateless rule definition's match attributes. You must specify a standard action and you can add custom actions.

                Note

                Network Firewall only forwards a packet for stateful rule inspection if you specify aws:forward_to_sfe for a rule that the packet matches, or if the packet doesn't match any stateless rule and you specify aws:forward_to_sfe for the StatelessDefaultActions setting for the FirewallPolicy .

                For every rule, you must specify exactly one of the following standard actions.

                • aws:pass - Discontinues all inspection of the packet and permits it to go to its intended destination.

                • aws:drop - Discontinues all inspection of the packet and blocks it from going to its intended destination.

                • aws:forward_to_sfe - Discontinues stateless inspection of the packet and forwards it to the stateful rule engine for inspection.

                Additionally, you can specify a custom action. To do this, you define a custom action by name and type, then provide the name you've assigned to the action in this Actions setting. For information about the options, see CustomAction .

                To provide more than one action in this setting, separate the settings with a comma. For example, if you have a custom PublishMetrics action that you've named MyMetricsAction , then you could specify the standard action aws:pass and the custom action with [“aws:pass”, “MyMetricsAction”] .

                • (string) --

            • Priority (integer) --

              A setting that indicates the order in which to run this rule relative to all of the rules that are defined for a stateless rule group. Network Firewall evaluates the rules in a rule group starting with the lowest priority setting. You must ensure that the priority settings are unique for the rule group.

              Each stateless rule group uses exactly one StatelessRulesAndCustomActions object, and each StatelessRulesAndCustomActions contains exactly one StatelessRules object. To ensure unique priority settings for your rule groups, set unique priorities for the stateless rules that you define inside any single StatelessRules object.

              You can change the priority settings of your rules at any time. To make it easier to insert rules later, number them so there's a wide range in between, for example use 100, 200, and so on.

        • CustomActions (list) --

          Defines an array of individual custom action definitions that are available for use by the stateless rules in this StatelessRulesAndCustomActions specification. You name each custom action that you define, and then you can use it by name in your StatelessRule RuleDefinition Actions specification.

          • (dict) --

            An optional, non-standard action to use for stateless packet handling. You can define this in addition to the standard action that you must specify.

            You define and name the custom actions that you want to be able to use, and then you reference them by name in your actions settings.

            You can use custom actions in the following places:

            • In a rule group's StatelessRulesAndCustomActions specification. The custom actions are available for use by name inside the StatelessRulesAndCustomActions where you define them. You can use them for your stateless rule actions to specify what to do with a packet that matches the rule's match attributes.

            • In a FirewallPolicy specification, in StatelessCustomActions . The custom actions are available for use inside the policy where you define them. You can use them for the policy's default stateless actions settings to specify what to do with packets that don't match any of the policy's stateless rules.

            • ActionName (string) --

              The descriptive name of the custom action. You can't change the name of a custom action after you create it.

            • ActionDefinition (dict) --

              The custom action associated with the action name.

              • PublishMetricAction (dict) --

                Stateless inspection criteria that publishes the specified metrics to Amazon CloudWatch for the matching packet. This setting defines a CloudWatch dimension value to be published.

                You can pair this custom action with any of the standard stateless rule actions. For example, you could pair this in a rule action with the standard action that forwards the packet for stateful inspection. Then, when a packet matches the rule, Network Firewall publishes metrics for the packet and forwards it.

                • Dimensions (list) --

                  • (dict) --

                    The value to use in an Amazon CloudWatch custom metric dimension. This is used in the PublishMetrics CustomAction . A CloudWatch custom metric dimension is a name/value pair that's part of the identity of a metric.

                    AWS Network Firewall sets the dimension name to CustomAction and you provide the dimension value.

                    For more information about CloudWatch custom metric dimensions, see Publishing Custom Metrics in the Amazon CloudWatch User Guide .

                    • Value (string) --

                      The value to use in the custom metric dimension.

  • RuleGroupResponse (dict) --

    The high-level properties of a rule group. This, along with the RuleGroup , define the rule group. You can retrieve all objects for a rule group by calling DescribeRuleGroup .

    • RuleGroupArn (string) --

      The Amazon Resource Name (ARN) of the rule group.

      Note

      If this response is for a create request that had DryRun set to TRUE , then this ARN is a placeholder that isn't attached to a valid resource.

    • RuleGroupName (string) --

      The descriptive name of the rule group. You can't change the name of a rule group after you create it.

    • RuleGroupId (string) --

      The unique identifier for the rule group.

    • Description (string) --

      A description of the rule group.

    • Type (string) --

      Indicates whether the rule group is stateless or stateful. If the rule group is stateless, it contains stateless rules. If it is stateful, it contains stateful rules.

    • Capacity (integer) --

      The maximum operating resources that this rule group can use. Rule group capacity is fixed at creation. When you update a rule group, you are limited to this capacity. When you reference a rule group from a firewall policy, Network Firewall reserves this capacity for the rule group.

      You can retrieve the capacity that would be required for a rule group before you create the rule group by calling CreateRuleGroup with DryRun set to TRUE .

    • RuleGroupStatus (string) --

      Detailed information about the current status of a rule group.

    • Tags (list) --

      The key:value pairs to associate with the resource.

      • (dict) --

        A key:value pair associated with an AWS resource. The key:value pair can be anything you define. Typically, the tag key represents a category (such as "environment") and the tag value represents a specific value within that category (such as "test," "development," or "production"). You can add up to 50 tags to each AWS resource.

        • Key (string) --

          The part of the key:value pair that defines a tag. You can use a tag key to describe a category of information, such as "customer." Tag keys are case-sensitive.

        • Value (string) --

          The part of the key:value pair that defines a tag. You can use a tag value to describe a specific value within a category, such as "companyA" or "companyB." Tag values are case-sensitive.

Sets the logging configuration for the specified firewall.

To change the logging configuration, retrieve the LoggingConfiguration by calling DescribeLoggingConfiguration , then change it and provide the modified object to this update call. You must change the logging configuration one LogDestinationConfig at a time inside the retrieved LoggingConfiguration object.

You can perform only one of the following actions in any call to UpdateLoggingConfiguration :

• Create a new log destination object by adding a single LogDestinationConfig array element to LogDestinationConfigs .

• Delete a log destination object by removing a single LogDestinationConfig array element from LogDestinationConfigs .

• Change the LogDestination setting in a single LogDestinationConfig array element.

You can't change the LogDestinationType or LogType in a LogDestinationConfig . To change these settings, delete the existing LogDestinationConfig object and create a new one, using two separate calls to this update operation.

Creates or updates an AWS Identity and Access Management policy for your rule group or firewall policy. Use this to share rule groups and firewall policies between accounts. This operation works in conjunction with the AWS Resource Access Manager (RAM) service to manage resource sharing for Network Firewall.

Use this operation to create or update a resource policy for your rule group or firewall policy. In the policy, you specify the accounts that you want to share the resource with and the operations that you want the accounts to be able to perform.

When you add an account in the resource policy, you then run the following Resource Access Manager (RAM) operations to access and accept the shared rule group or firewall policy.

• GetResourceShareInvitations - Returns the Amazon Resource Names (ARNs) of the resource share invitations.

• AcceptResourceShareInvitation - Accepts the share invitation for a specified resource share.

For additional information about resource sharing using RAM, see AWS Resource Access Manager User Guide .

type UpdateToken

string

param UpdateToken

An optional token that you can use for optimistic locking. Network Firewall returns a token to your requests that access the firewall. The token marks the state of the firewall resource at the time of the request.

To make an unconditional change to the firewall, omit the token in your update request. Without the token, Network Firewall performs your updates regardless of whether the firewall has changed since you last retrieved it.

To make a conditional change to the firewall, provide the token in your update request. Network Firewall uses the token to ensure that the firewall hasn't changed since you last retrieved it. If it has changed, the operation fails with an InvalidTokenException . If this happens, retrieve the firewall again to get a current copy of it with a new token. Reapply your changes as needed, then try the operation again using the new token.

type FirewallArn

string

param FirewallArn

The Amazon Resource Name (ARN) of the firewall.

You must specify the ARN or the name, and you can specify both.
