| type: "manual" | ||
| 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). | ||
