Title

RHEL 8 audit records must contain information to establish what type of events occurred, the source of events, where events occurred, and the outcome of events. (Cat II impact)

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 RHEL 8 audit logs provides a means of investigating an attack, recognizing resource utilization or capacity thresholds, or identifying an improperly configured RHEL 8 system.

Check Content

Verify the audit service is configured to produce audit records with the following command: $ sudo systemctl status auditd.service auditd.service - Security Auditing Service Loaded:loaded (/usr/lib/systemd/system/auditd.service; enabled; vendor preset: enabled) Active: active (running) since Tues 2020-12-11 12:56:56 EST; 4 weeks 0 days ago If the audit service is not "active" and "running", this is a finding.

Fix Text

Configure the audit service to produce audit records containing the information needed to establish when (date and time) an event occurred with the following commands: $ sudo systemctl enable auditd.service $ sudo systemctl start auditd.service
