info:
  name: Ensure audit-log-path set
  author: princechaddha
  severity: medium
  description: Checks if the audit-log-path argument is properly set in the Kubernetes API server configuration, which is essential for maintaining a reliable audit trail.
  impact: |
    Without the audit-log-path argument, Kubernetes does not record API server audit logs, reducing the visibility into operations and making it harder to detect and respond to malicious activities.
  remediation: |
    Configure the Kubernetes API server to include the audit-log-path argument pointing to a secure, writeable directory where audit logs will be stored. Ensure that this directory is properly secured and regularly monitored.
