Title

The Ubuntu operating system must generate audit records when successful/unsuccessful attempts to use the kmod command. (Cat II impact)

Discussion

Without generating audit records that are specific to the security and mission needs of the organization, 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).

Check Content

Verify if the Ubuntu operating system is configured to audit the execution of the module management program "kmod". Check the currently configured audit rules with the following command: # sudo auditctl -l | grep kmod -w /bin/kmod -p x -k module If the command does not return a line, or the line is commented out, this is a finding. Note: The '-k' allows for specifying an arbitrary identifier and the string after it does not need to match the example output above.

Fix Text

Configure the Ubuntu operating system to audit the execution of the module management program "kmod". Add or update the following rule in the "/etc/audit/rules.d/stig.rules" file. -w /bin/kmod -p x -k modules Note: The "root" account must be used to view/edit any files in the /etc/audit/rules.d/ directory. In order to reload the rules file, issue the following command: # sudo augenrules --load
