UBTU-18-010007 - The Ubuntu operating system audit event multiplexor must be configured to off-load audit logs onto a different system in real time, if the system is interconnected.
Information
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.
Solution
Configure the audit event multiplexor to off-load audit records to a different system or storage media from the system being audited.Install the audisp-remote plugin:
# sudo apt-get install audispd-plugins -y
Set the audisp-remote plugin as active, by editing the /etc/audisp/plugins.d/au-remote.conf file:
# sudo sed -i -E 's/actives*=s*no/active = yes/' /etc/audisp/plugins.d/au-remote.conf
Set the address of the remote machine, by editing the /etc/audisp/audisp-remote.conf file:
# sudo sed -i -E 's/(remote_servers*=).*/1 <remote addr>/' audisp-remote.conf
where <remote addr> must be substituted by the address of the remote server receiving the audit log.
Make the audit service reload its configuration files:
# sudo systemctl restart auditd.service
