OL 9 must generate audit records for all account creations, modifications, disabling, and termination events that affect /var/log/tallylog.

Without generating audit records specific to the security and mission needs of the organization, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one.

Satisfies: SRG-OS-000392-GPOS-00172, SRG-OS-000470-GPOS-00214, SRG-OS-000473-GPOS-00218

Verify that OL 9 generates audit records for all account creations, modifications, disabling, and termination events that affect /var/log/tallylog with the following command:

$ sudo auditctl -l | grep /var/log/tallylog -w /var/log/tallylog -p wa -k logins

If the command does not return a line or the line is commented out, this is a finding.

Configure OL 9 to generate audit records for all account creations, modifications, disabling, and termination events that affect /var/log/tallylog.

Add or update the following file system rule to "/etc/audit/rules.d/audit.rules":

-w /var/log/tallylog -p wa -k logins

The audit daemon must be restarted for the changes to take effect.

Restart auditd: $ sudo service auditd restart
