Ubuntu 22.04

Ubuntu 22.04 LTS must permit only authorized groups to own the audit configuration files

STIG ID: UBTU-22-653075 | SRG: SRG-OS-000063-GPOS-00032 | Severity: Medium | CCI: CCI-000171 | Vulnerability ID: V-260603

Description

Without the capability to restrict which roles and individuals 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

C-64332r953620_chk

Verify that "/etc/audit/audit.rules", "/etc/audit/auditd.conf", and "/etc/audit/rules.d/*" files are owned by root group by using the following command: $ sudo ls -al /etc/audit/audit.rules /etc/audit/auditd.conf /etc/audit/rules.d/* | awk '{print $4, $9}' root /etc/audit/audit.rules root /etc/audit/auditd.conf root /etc/audit/rules.d/audit.rules If "/etc/audit/audit.rules", "/etc/audit/auditd.conf", or "/etc/audit/rules.d/*" files are owned by a group other than "root", this is a finding.

Fix

F-64240r953621_fix

Configure "/etc/audit/audit.rules", "/etc/audit/rules.d/*", and "/etc/audit/auditd.conf" files to be owned by root group by using the following command: $ sudo chown -R :root /etc/audit/audit.rules /etc/audit/auditd.conf /etc/audit/rules.d/*
