remediation: |

|
|
Review the audit policy provided for the cluster and ensure that it covers
|
||
|
|
at least the following areas,
|
||
|
|
- Access to Secrets managed by the cluster. Care should be taken to only
|
||
|
|
log Metadata for requests to Secrets, ConfigMaps, and TokenReviews, in
|
||
|
|
order to avoid risk of logging sensitive data.
|
||
|
|
- Modification of Pod and Deployment objects.
|
||
|
|
- Use of `pods/exec`, `pods/portforward`, `pods/proxy` and `services/proxy`.
|
||
|
|
For most requests, minimally logging at the Metadata level is recommended
|
||
|
|
(the most basic level of logging).
