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).

Use the following steps to start a manual image scan using the AWS Management Console.
|
