Discussion

In addition to auditing new user and group accounts, these watches will alert the system administrator(s) to any modifications. Any unexpected users, groups, or modifications should be investigated for legitimacy.

Check Content

Verify TOSS 5 generates audit records for all account creations, modifications, disabling, and termination events that affect "/etc/security/opasswd" using the following command:

$ sudo auditctl -l | egrep '(/etc/security/opasswd)' 

-w /etc/security/opasswd -p wa -k identity

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

Fix Text

Configure TOSS 5 to generate audit records for all account creations, modifications, disabling, and termination events that affect "/etc/security/opasswd".

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

-w /etc/security/opasswd -p wa -k identity

Restart the audit daemon for the changes to take effect.
