The Ubuntu operating system must allow only the Information System Security Manager (ISSM) (or individuals or roles appointed by the ISSM) to select which auditable events are to be audited.

Finding ID Version Rule ID IA Controls Severity
V-75647 UBTU-16-020150 SV-90327r1_rule Medium
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 Text ( C-75351r1_chk )
Verify that the /etc/audit/audit.rule and /etc/audit/auditd.conf file have a mode of 0640 or less permissive by using the following command:

# sudo ls -la /etc/audit/audit.rules

-rw-r----- 1 root root 1280 Feb 16 17:09 audit.rules
-rw-r----- 1 root root 621 Sep 22 2014 auditd.conf

If the "/etc/audit/audit.rule" or "/etc/audit/auditd.conf" file have a mode more permissive than "0640", this is a finding.
Fix Text (F-82275r1_fix)
Configure the /etc/audit/audit.rule and /etc/audit/auditd.conf file to have a mode of 0640 with the following command:

# sudo chmod 0640 /etc/audit/audit.rule
# sudo chmod 0640 /etc/audit/audit.conf
