cross-account

Filter file systems whose policy grants access outside of allowed accounts or organizations.

A file system without a policy does not evaluate IAM for NFS access at all; combine with has-statement to require a policy to be attached.

example:

  - name: s3files-cross-account
    resource: aws.s3files-file-system

rename-tag

Rename an existing tag key to a new value.

example:

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.

- name: rename-tags-example
