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).

  selector:
    enum:
    - previous
    - date
    - locked

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
