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 Content

Verify Amazon Linux 2023 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 Text

Configure Amazon Linux 2023 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

To load the rules to the kernel immediately, use the following command: 

$ sudo augenrules --load
