6.3.4.17 Ensure audit log files group owner is root

Information

The operating system's audit log directory must be group-owned by root to prevent unauthorized read access.

Unauthorized disclosure of audit records can reveal system and configuration data to attackers, thus compromising its confidentiality.

Audit information includes all information (e.g., audit records, audit settings, audit reports) needed to successfully audit the operating system's activity.

Satisfies: SRG-OS-000057-GPOS-00027, SRG-OS-000058-GPOS-00028, SRG-OS-000059-GPOS-00029

Solution

Configure the audit log to be protected from unauthorized read access by setting the correct group-owner as "root" with the following command:

# chgrp root [audit_log_directory]

Replace "[audit_log_directory]" with the correct audit log directory path, by default this location is usually "/var/log/audit".
