Description
Information stored in one location is vulnerable to accidental or incidental deletion or alteration. Off-loading is a common process in information systems with limited audit storage capacity. One method of off-loading audit logs in Oracle Linux is with the use of the audisp-remote dameon. Without the configuration of the "au-remote" plugin, the audisp-remote daemon will not off load the logs from the system being audited. Satisfies: SRG-OS-000342-GPOS-00133, SRG-OS-000479-GPOS-00224

ℹ️ Check
Verify the "au-remote" plugin is configured to always off-load audit logs using the audisp-remote daemon: # cat /etc/audisp/plugins.d/au-remote.conf \| grep -v "^#" active = yes direction = out path = /sbin/audisp-remote type = always format = string If "active" is not set to "yes", "direction" is not set to "out", "path" is not set to "/sbin/audisp-remote", "type is not set to "always", or any of the lines are commented out, ask the System Administrator to indicate how the audit logs are off-loaded to a different system or storage media. If there is no evidence that the system is configured to off-load audit logs to a different system or storage media, this is a finding.

✔️ Fix
Edit the /etc/audisp/plugins.d/au-remote.conf file and add or update the following values: active = yes direction = out path = /sbin/audisp-remote type = always The audit daemon must be restarted for changes to take effect: # service auditd restart
