C-0160 - Ensure that a minimal audit policy is created
Description of the the issue
Logging is an important detective control for all systems, to detect potential unauthorised access.
What does this control test
Kubernetes can audit the details of requests made to the API server. The
--audit-policy-file flag must be set for this logging to be enabled.
How to check it manually
Run the following command on one of the cluster master nodes:
ps -ef | grep kube-apiserver
Verify that the
--audit-policy-file is set. Review the contents of the file specified and ensure that it contains a valid audit policy.
Create an audit policy file for your cluster.
Audit logs will be created on the master nodes, which will consume disk space. Care should be taken to avoid generating too large volumes of log information as this could impact the available of the cluster nodes.
--audit-policy-file flag is specified, no auditing will be carried out.
