Verify the audit event multiplexor is configured to off-load audit records to a different system or storage media from the system being audited. Check that audisp-remote plugin is installed: # sudo dpkg -s audispd-plugins If status is "not installed", this is a finding. Check that the records are being off-loaded to a remote server with the following command: # sudo grep -i active /etc/audisp/plugins.d/au-remote.conf active = yes If "active" is not set to "yes", or the line is commented out, this is a finding. Check that audisp-remote plugin is configured to send audit logs to a different system: # sudo grep -i ^remote_server /etc/audisp/audisp-remote.conf remote_server = 192.168.122.126 If the remote_server parameter is not set or is set with a local address, or is set with invalid address, this is a finding. |
