RHEL 10 must enforce mode "0640" or less for the "/etc/audit/auditd.conf" file to prevent unauthorized access.

STIG ID: RHEL-10-900000  |  SRG: SRG-OS-000063-GPOS-00032 |  Severity: medium (CAT II)  |  CCI: CCI-000171 |  Vulnerability Id: V-281364

Vulnerability Discussion

Without the capability to restrict the roles and individuals that can select which events are audited, unauthorized personnel may be able to prevent the auditing of critical events. Misconfigured audits may degrade the system's performance by overwhelming the audit log. Misconfigured audits may also make it more difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one.

Check

Verify RHEL 10 enforces the mode of "/etc/audit/auditd.conf" with the following command:

$ sudo stat -c "%a %n" /etc/audit/auditd.conf
640 /etc/audit/auditd.conf

If "/etc/audit/auditd.conf" does not have a mode of "0640", this is a finding.

Fix

Configure RHEL 10 to set the mode of the "/etc/audit/auditd.conf" file to "0640" with the following command:

$ sudo chmod 0640 /etc/audit/auditd.conf
