Fix Recommendation

Configure TOSS to audit the execution of the module management program "kmod" by adding or updating the following line to "/etc/audit/rules.d/audit.rules":

-a always,exit -F path=/usr/bin/kmod -F perm=x -F auid>=1000 -F auid!=unset -k modules

The audit daemon must be restarted for the changes to take effect.

Check Contents

Verify that TOSS is configured to audit the execution of the module management program "kmod", by running the following command:

$ sudo grep "/usr/bin/kmod" /etc/audit/audit.rules

-a always,exit -F path=/usr/bin/kmod -F perm=x -F auid>=1000 -F auid!=unset -k modules

If the command does not return a line, or the line is commented out, this is a finding.
