AWS CloudTrail

2015/12/17 - AWS CloudTrail - 3 updated api methods

CreateTrail (updated) Link ¶
Changes (both) 
{'IsMultiRegionTrail': 'boolean'}

Creates a trail that specifies the settings for delivery of log data to an Amazon S3 bucket. A maximum of five trails can exist in a region, irrespective of the region in which they were created.

Request Syntax

client.create_trail(
    Name='string',
    S3BucketName='string',
    S3KeyPrefix='string',
    SnsTopicName='string',
    IncludeGlobalServiceEvents=True|False,
    IsMultiRegionTrail=True|False,
    EnableLogFileValidation=True|False,
    CloudWatchLogsLogGroupArn='string',
    CloudWatchLogsRoleArn='string',
    KmsKeyId='string'
)
type Name

string

param Name

[REQUIRED]

Specifies the name of the trail. The name must meet the following requirements:

  • Contain only ASCII letters (a-z, A-Z), numbers (0-9), periods (.), underscores (_), or dashes (-)

  • Start with a letter or number, and end with a letter or number

  • Be between 3 and 128 characters

  • Have no adjacent periods, underscores or dashes. Names like my-_namespace and my--namespace are invalid.

  • Not be in IP address format (for example, 192.168.5.4)

type S3BucketName

string

param S3BucketName

[REQUIRED]

Specifies the name of the Amazon S3 bucket designated for publishing log files. See Amazon S3 Bucket Naming Requirements .

type S3KeyPrefix

string

param S3KeyPrefix

Specifies the Amazon S3 key prefix that comes after the name of the bucket you have designated for log file delivery. For more information, see Finding Your CloudTrail Log Files . The maximum length is 200 characters.

type SnsTopicName

string

param SnsTopicName

Specifies the name of the Amazon SNS topic defined for notification of log file delivery. The maximum length is 256 characters.

type IncludeGlobalServiceEvents

boolean

param IncludeGlobalServiceEvents

Specifies whether the trail is publishing events from global services such as IAM to the log files.

type IsMultiRegionTrail

boolean

param IsMultiRegionTrail

Specifies whether the trail is created in the current region or in all regions. The default is false.

type EnableLogFileValidation

boolean

param EnableLogFileValidation

Specifies whether log file integrity validation is enabled. The default is false.

Note

When you disable log file integrity validation, the chain of digest files is broken after one hour. CloudTrail will not create digest files for log files that were delivered during a period in which log file integrity validation was disabled. For example, if you enable log file integrity validation at noon on January 1, disable it at noon on January 2, and re-enable it at noon on January 10, digest files will not be created for the log files delivered from noon on January 2 to noon on January 10. The same applies whenever you stop CloudTrail logging or delete a trail.

type CloudWatchLogsLogGroupArn

string

param CloudWatchLogsLogGroupArn

Specifies a log group name using an Amazon Resource Name (ARN), a unique identifier that represents the log group to which CloudTrail logs will be delivered. Not required unless you specify CloudWatchLogsRoleArn.

type CloudWatchLogsRoleArn

string

param CloudWatchLogsRoleArn

Specifies the role for the CloudWatch Logs endpoint to assume to write to a user's log group.

type KmsKeyId

string

param KmsKeyId

Specifies the KMS key ID to use to encrypt the logs delivered by CloudTrail. The value can be a an alias name prefixed by "alias/", a fully specified ARN to an alias, a fully specified ARN to a key, or a globally unique identifier.

Examples:

  • alias/MyAliasName

  • arn:aws:kms:us-east-1:123456789012:alias/MyAliasName

  • arn:aws:kms:us-east-1:123456789012:key/12345678-1234-1234-1234-123456789012

UpdateTrail (updated) Link ¶
Changes (both) 
{'IsMultiRegionTrail': 'boolean'}

Updates the settings that specify delivery of log files. Changes to a trail do not require stopping the CloudTrail service. Use this action to designate an existing bucket for log delivery. If the existing bucket has previously been a target for CloudTrail log files, an IAM policy exists for the bucket. UpdateTrail must be called from the region in which the trail was created; otherwise, an InvalidHomeRegionException is thrown.

Request Syntax

client.update_trail(
    Name='string',
    S3BucketName='string',
    S3KeyPrefix='string',
    SnsTopicName='string',
    IncludeGlobalServiceEvents=True|False,
    IsMultiRegionTrail=True|False,
    EnableLogFileValidation=True|False,
    CloudWatchLogsLogGroupArn='string',
    CloudWatchLogsRoleArn='string',
    KmsKeyId='string'
)
type Name

string

param Name

[REQUIRED]

Specifies the name of the trail or trail ARN. If Name is a trail name, the string must meet the following requirements:

  • Start with a letter or number, and end with a letter or number

  • Be between 3 and 128 characters

  • Have no adjacent periods, underscores or dashes. Names like my-_namespace and my--namespace are invalid.

  • Not be in IP address format (for example, 192.168.5.4)

If Name is a trail ARN, it must be in the format arn:aws:cloudtrail:us-east-1:123456789012:trail/MyTrail .

type S3BucketName

string

param S3BucketName

Specifies the name of the Amazon S3 bucket designated for publishing log files. See Amazon S3 Bucket Naming Requirements .

type S3KeyPrefix

string

param S3KeyPrefix

Specifies the Amazon S3 key prefix that comes after the name of the bucket you have designated for log file delivery. For more information, see Finding Your CloudTrail Log Files . The maximum length is 200 characters.

type SnsTopicName

string

param SnsTopicName

Specifies the name of the Amazon SNS topic defined for notification of log file delivery. The maximum length is 256 characters.

type IncludeGlobalServiceEvents

boolean

param IncludeGlobalServiceEvents

Specifies whether the trail is publishing events from global services such as IAM to the log files.

type IsMultiRegionTrail

boolean

param IsMultiRegionTrail

Specifies whether the trail applies only to the current region or to all regions. The default is false. If the trail exists only in the current region and this value is set to true, shadow trails (replications of the trail) will be created in the other regions. If the trail exists in all regions and this value is set to false, the trail will remain in the region where it was created, and its shadow trails in other regions will be deleted.

type EnableLogFileValidation

boolean

param EnableLogFileValidation

Specifies whether log file validation is enabled. The default is false.

Note

When you disable log file integrity validation, the chain of digest files is broken after one hour. CloudTrail will not create digest files for log files that were delivered during a period in which log file integrity validation was disabled. For example, if you enable log file integrity validation at noon on January 1, disable it at noon on January 2, and re-enable it at noon on January 10, digest files will not be created for the log files delivered from noon on January 2 to noon on January 10. The same applies whenever you stop CloudTrail logging or delete a trail.

type CloudWatchLogsLogGroupArn

string

param CloudWatchLogsLogGroupArn

Specifies a log group name using an Amazon Resource Name (ARN), a unique identifier that represents the log group to which CloudTrail logs will be delivered. Not required unless you specify CloudWatchLogsRoleArn.

type CloudWatchLogsRoleArn

string

param CloudWatchLogsRoleArn

Specifies the role for the CloudWatch Logs endpoint to assume to write to a user's log group.

type KmsKeyId

string

param KmsKeyId

Specifies the KMS key ID to use to encrypt the logs delivered by CloudTrail. The value can be a an alias name prefixed by "alias/", a fully specified ARN to an alias, a fully specified ARN to a key, or a globally unique identifier.

Examples:

  • arn:aws:kms:us-east-1:123456789012:alias/MyAliasName

  • arn:aws:kms:us-east-1:123456789012:key/12345678-1234-1234-1234-123456789012
