Discussion

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-000037-GPOS-00015, SRG-OS-000042-GPOS-00020, SRG-OS-000062-GPOS-00031, SRG-OS-000392-GPOS-00172, SRG-OS-000462-GPOS-00206, SRG-OS-000471-GPOS-00215, SRG-OS-000473-GPOS-00218, SRG-OS-000470-GPOS-00214

Check Procedure

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

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

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

Fix Action

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

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

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

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

$ sudo service auditd restart
