Properties for defining a CfnAccountPolicy.

Example

// The code below shows an example of how to instantiate this type.
// The values are placeholders you should change.
import { aws_logs as logs } from 'aws-cdk-lib';
const cfnAccountPolicyProps: logs.CfnAccountPolicyProps = {
  policyDocument: 'policyDocument',
  policyName: 'policyName',
  policyType: 'policyType',

  // the properties below are optional
  scope: 'scope',
  selectionCriteria: 'selectionCriteria',
};

Properties

Name	Type	Description
policyDocument	`string`	Specify the policy, in JSON.
policyName	`string`	A name for the policy.
policyType	`string`	The type of policy that you're creating or updating.
scope?	`string`	Currently the only valid value for this parameter is `ALL` , which specifies that the policy applies to all log groups in the account.
selectionCriteria?	`string`	Use this parameter to apply the new policy to a subset of log groups in the account.

policyDocument

Type: string

Specify the policy, in JSON.

Data protection policy

A data protection policy must include two JSON blocks:

The first block must include both a DataIdentifer array and an Operation property with an Audit action. The DataIdentifer array lists the types of sensitive data that you want to mask. For more information about the available options, see Types of data that you can mask .

The Operation property with an Audit action is required to find the sensitive data terms. This Audit action must contain a FindingsDestination object. You can optionally use that FindingsDestination object to list one or more destinations to send audit findings to. If you specify destinations such as log groups, Firehose streams, and S3 buckets, they must already exist.

The second block must include both a DataIdentifer array and an Operation property with an Deidentify action. The DataIdentifer array must exactly match the DataIdentifer array in the first block of the policy.

The Operation property with the Deidentify action is what actually masks the data, and it must contain the "MaskConfig": {} object. The "MaskConfig": {} object must be empty.

The contents of the two DataIdentifer arrays must match exactly.

In addition to the two JSON blocks, the policyDocument can also include Name , Description , and Version fields. The Name is different than the operation's policyName parameter, and is used as a dimension when CloudWatch Logs reports audit findings metrics to CloudWatch .

The JSON specified in policyDocument can be up to 30,720 characters long.

Subscription filter policy

A subscription filter policy can include the following attributes in a JSON block:

DestinationArn The ARN of the destination to deliver log events to. Supported destinations are:
An Kinesis Data Streams data stream in the same account as the subscription policy, for same-account delivery.
An Firehose data stream in the same account as the subscription policy, for same-account delivery.
A Lambda function in the same account as the subscription policy, for same-account delivery.
A logical destination in a different account created with PutDestination , for cross-account delivery. Kinesis Data Streams and Firehose are supported as logical destinations.
RoleArn The ARN of an IAM role that grants CloudWatch Logs permissions to deliver ingested log events to the destination stream. You don't need to provide the ARN when you are working with a logical destination for cross-account delivery.
FilterPattern A filter pattern for subscribing to a filtered stream of log events.
Distribution The method used to distribute log data to the destination. By default, log data is grouped by log stream, but the grouping can be set to Random for a more even distribution. This property is only applicable when the destination is an Kinesis Data Streams data stream.

Field index policy

A field index filter policy can include the following attribute in a JSON block:

Fields The array of field indexes to create.

The following is an example of an index policy document that creates two indexes, RequestId and TransactionId .

"policyDocument": "{ \"Fields\": [ \"RequestId\", \"TransactionId\" ] }"

Transformer policy

A transformer policy must include one JSON block with the array of processors and their configurations. For more information about available processors, see Processors that you can use .

policyName

Type: string

A name for the policy.

This must be unique within the account.

policyType

Type: string

The type of policy that you're creating or updating.

scope?

Type: string (optional)

Currently the only valid value for this parameter is ALL , which specifies that the policy applies to all log groups in the account.

If you omit this parameter, the default of ALL is used. To scope down a subscription filter policy to a subset of log groups, use the SelectionCriteria parameter.

selectionCriteria?

Type: string (optional)

Use this parameter to apply the new policy to a subset of log groups in the account.

You need to specify SelectionCriteria only when you specify SUBSCRIPTION_FILTER_POLICY , FIELD_INDEX_POLICY or TRANSFORMER_POLICY for PolicyType .

If PolicyType is SUBSCRIPTION_FILTER_POLICY , the only supported SelectionCriteria filter is LogGroupName NOT IN []

If PolicyType is FIELD_INDEX_POLICY or TRANSFORMER_POLICY , the only supported SelectionCriteria filter is LogGroupNamePrefix

The SelectionCriteria string can be up to 25KB in length. The length is determined by using its UTF-8 bytes.

Using the SelectionCriteria parameter with SUBSCRIPTION_FILTER_POLICY is useful to help prevent infinite loops. For more information, see Log recursion prevention .
