has-statement
Find resources with matching access policy statements.
If you want to return resource statements that include the listed Action or NotAction, you can use PartialMatch instead of an exact match.
- example:
policies:
- name: sns-check-statement-id
resource: sns
filters:
- type: has-statement
statement_ids:
- BlockNonSSL
policies:
- name: sns-check-block-non-ssl

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).

- previous

- 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 value: AWS
