Vulnerability Discussion

Without establishing what type of events occurred, the source of events, where events occurred, and the outcome of events, it would be difficult to establish, correlate, and investigate the events leading up to an outage or attack.

Audit record content that may be necessary to satisfy this requirement includes, for example, time stamps, source and destination addresses, user/process identifiers, event descriptions, success/fail indications, filenames involved, and access control or flow control rules invoked.

Associating event types with detected events in audit logs provides a means of investigating an attack, recognizing resource usage or capacity thresholds, or identifying an improperly configured AlmaLinux OS 9 system.

Check

Verify that the audit package is installed with the following command:

$ dnf list --installed audit

Installed Packages
audit.x86_64 3.0.7-103.el9 @anaconda

If the "audit" package is not installed, this is a finding.

Fix

Install the AlmaLinux OS 9 audit package with the following command:

$ dnf install audit
