Title
The audit system must be configured to audit any usage of the insmod command. (Cat II impact)
Discussion
Without the capability to generate audit records, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. Audit records can be generated from various components within the information system (e.g., module or policy filter). The list of audited events is the set of events for which audits are to be generated. This set of events is typically a subset of the list of all events for which the system is capable of generating audit records. DoD has defined the list of events for which the Ubuntu operating system will provide an audit record generation capability as the following: 1) Successful and unsuccessful attempts to access, modify, or delete privileges, security objects, security levels, or categories of information (e.g., classification levels); 2) Access actions, such as successful and unsuccessful logon attempts, privileged activities or other system-level access, starting and ending time for user access to the system, concurrent logons from different workstations, successful and unsuccessful accesses to objects, all program initiations, and all direct access to the information system; 3) All account creations, modifications, disabling, and terminations; and 4) All kernel module load, unload, and restart actions.

Check Content
Verify if the Ubuntu operating system is configured to audit the execution of the module management program "insmod", by running the following command: # sudo grep "/sbin/insmod" /etc/audit/audit.rules -w /sbin/insmod -p x -k modules If the command does not return a line, or the line is commented out, this is a finding.
Fix Text
Configure the Ubuntu operating system to audit the execution of the module management program "insmod", by adding the following line to "/etc/audit/audit.rules": -w /sbin/insmod -p x -k modules The audit daemon must be restarted for the changes to take effect. To restart the audit daemon, run the following command: # sudo systemctl restart auditd.service
