flow-logs

Are flow logs enabled on the resource.

ie to find all vpcs with flows logs disabled we can do this

example:

policies:
  - name: flow-logs-enabled
    resource: vpc
    filters:
      - flow-logs

or to find all vpcs with flow logs but that don’t match a particular configuration.

example:

policies:
  - name: flow-mis-configured
    resource: vpc
    filters:
      - not:
        - type: flow-logs
          enabled: true
          set-op: or
          op: equal
          # equality operator applies to following keys
          traffic-type: all
          status: active
          log-group: vpc-logs

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:
    - json-diff
required:
- type
