Title

Ubuntu OS must permit only authorized accounts to own the audit configuration files. (Cat II impact)

Discussion

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 Content

Verify "/etc/audit/audit.rules", "/etc/audit/auditd.conf", and "/etc/audit/rules.d/*" files are owned by root account by using the following command: $ sudo ls -al /etc/audit/audit.rules /etc/audit/auditd.conf /etc/audit/rules.d/* | awk '{print $3, $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 user other than "root", this is a finding.

Fix Text

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