Canonical Ubuntu 20.04 LTS STIG:
UBTU-20-010300
(in versions v1 r12 through v1 r1)
Title
The Ubuntu operating system must have a crontab script running weekly to offload audit events of standalone systems. (Cat III impact)
Discussion
Information stored in one location is vulnerable to accidental or incidental deletion or alteration. Offloading is a common process in information systems with limited audit storage capacity.
Check Content
Note: If this is an interconnected system, this is Not Applicable. Verify there is a script that offloads audit data and that script runs weekly. Check if there is a script in the "/etc/cron.weekly" directory that offloads audit data: # sudo ls /etc/cron.weekly audit-offload Check if the script inside the file does offloading of audit logs to external media. If the script file does not exist or does not offload audit logs, this is a finding.
Fix Text
Create a script that offloads audit logs to external media and runs weekly. The script must be located in the "/etc/cron.weekly" directory.
