Assessment Title

Rule Text

OL 9 must be configured to offload audit records onto a different system from the system being audited via syslog.

Description

Discussion Text

The auditd service does not include the ability to send audit records to a centralized server for management directly. However, it can use a plug-in for audit event multiplexor (audispd) to pass audit records to the local syslog server. Satisfies: SRG-OS-000342-GPOS-00133, SRG-OS-000479-GPOS-00224

How this relates to the STIG checklist: STIG vs SCAP benchmark.

Remediation

Configure OL 9 to offload audit records onto a different system from the system being audited via syslog.

Edit the /etc/audit/plugins.d/syslog.conf file and add or update the "active" option:

active = yes

The audit daemon must be restarted for changes to take effect.

Restart auditd:
$ sudo service auditd restart
