Vulnerability Discussion

Without generating audit records that 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.

Audit records can be generated from various components within the information system (e.g., module or policy filter).

Check

Verify the operating system generates audit records when successful account access events occur.

Check the file system rules in "/etc/audit/audit.rules" with the following commands:

# grep -i /var/log/lastlog /etc/audit/audit.rules

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

If the command does not return any output, this is a finding.

Fix

Configure the operating system to generate audit records when successful account access events occur.

Add or update the following rule in "/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.
