        statements:
          - Effect: Deny
            Action: 'SNS:Publish'
            Principal: '*'
            Condition:

json-diff

Compute the diff from the current resource to a previous version.

A resource matches the filter if a diff exists between the current resource and the selected revision.

Utilizes config as a resource revision database.

Revisions can be selected by date, against the previous version, and against a locked version (requires use of is-locked filter).

properties:
  selector:
    enum:
    - previous
    - date
    - locked
  selector_value:
    type: string
  type:
    enum:

Permissions - config:GetResourceConfigHistory

kms-key

Filter a resource by its associated kms key and optionally the aliasname of the kms key by using ‘c7n:AliasName’

example:

Match a specific key alias:

policies:
    - name: dms-encrypt-key-check
      resource: dms-instance
      filters:
        - type: kms-key
          key: "c7n:AliasName"
          value: alias/aws/dms

Or match against native key attributes such as KeyManager, which more explicitly distinguishes between AWS and CUSTOMER-managed keys. The above policy can also be written as:

policies:
    - name: dms-aws-managed-key
      resource: dms-instance
      filters:
        - type: kms-key
          key: KeyManager

Action to delete a SQS queue

To prevent unwanted deletion of SQS queues, it is recommended to include a filter

example:

policies:
  - name: sqs-delete
    resource: sqs
    filters:
      - KmsMasterKeyId: absent
    actions:
      - type: delete

rename Application, and Bap to App, if a resource has both of the old keys then we’ll use the value specified by Application, which is based on the order of values of old_keys.

policies:
- name: rename-tags-example
  resource: aws.log-group
  filters:
    - or:
      - "tag:Bap": present
      - "tag:Application": present

    filters:
      - KmsMasterKeyId: absent
