[ aws . securitylake ]



Adds a third-party custom source in Amazon Security Lake, from the Amazon Web Services Region where you want to create a custom source. Security Lake can collect logs and events from third-party custom sources. After creating the appropriate IAM role to invoke Glue crawler, use this API to add a custom source name in Security Lake. This operation creates a partition in the Amazon S3 bucket for Security Lake as the target location for log files from the custom source. In addition, this operation also creates an associated Glue table and an Glue crawler.

--configuration (structure)

The configuration for the third-party custom source.

crawlerConfiguration -> (structure)

The configuration for the Glue Crawler for the third-party custom source.

roleArn -> (string)

The Amazon Resource Name (ARN) of the Identity and Access Management (IAM) role to be used by the Glue crawler. The recommended IAM policies are:

  • The managed policy AWSGlueServiceRole
  • A custom policy granting access to your Amazon S3 Data Lake

providerIdentity -> (structure)

The identity of the log provider for the third-party custom source.

externalId -> (string)

The external ID used to estalish trust relationship with the AWS identity.

principal -> (string)

The AWS identity principal.

Shorthand Syntax:


JSON Syntax:

  "crawlerConfiguration": {
    "roleArn": "string"
  "providerIdentity": {
    "externalId": "string",
    "principal": "string"

--event-classes (list)

The Open Cybersecurity Schema Framework (OCSF) event classes which describes the type of data that the custom source will send to Security Lake. The supported event classes are:




"string" "string" ...

--source-name (string)

Specify the name for a third-party custom source. This must be a Regionally unique value.

--source-version (string)

Specify the source version for the third-party custom source, to limit log collection to a specific version of custom data source.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json
  • text
  • table
  • yaml
  • yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64
  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.


source -> (structure)

The created third-party custom source.

attributes -> (structure)

The attributes of a third-party custom source.

crawlerArn -> (string)

The ARN of the Glue crawler.

databaseArn -> (string)

The ARN of the Glue database where results are written, such as: arn:aws:daylight:us-east-1::database/sometable/* .

tableArn -> (string)

The ARN of the Glue table.

provider -> (structure)

The details of the log provider for a third-party custom source.

location -> (string)

The location of the partition in the Amazon S3 bucket for Security Lake.

roleArn -> (string)

The ARN of the IAM role to be used by the entity putting logs into your custom source partition. Security Lake will apply the correct access policies to this role, but you must first manually create the trust policy for this role. The IAM role name must start with the text ‘Security Lake’. The IAM role must trust the logProviderAccountId to assume the role.

sourceName -> (string)

The name for a third-party custom source. This must be a Regionally unique value.

sourceVersion -> (string)

The version for a third-party custom source. This must be a Regionally unique value.
