The Ubuntu operating system must be configured so that audit log files cannot be read or write-accessible by unauthorized users.
An XCCDF Rule
Description
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.

A Manual Procedure

First determine where the audit logs are stored with the following command:
# sudo grep -iw log_file /etc/audit/auditd.conf
log_file = /var/log/audit/audit.log
