The Ubuntu operating system must permit only authorized accounts ownership of the audit log files.
An XCCDF Rule
Description
<VulnDiscussion>If audit information were to become compromised, then forensic analysis and discovery of the true source of potentially malicious system activity is impossible to achieve. To ensure the veracity of audit information, the operating system must protect audit information from unauthorized modification. Audit information includes all information (e.g., audit records, audit settings, audit reports) needed to successfully audit information system activity.
