Fix Recommendation

Configure Amazon Linux 2023 to generate an audit event for any successful/unsuccessful use of the "init_module" and "finit_module" system calls by adding or updating the following rule in the "/etc/audit/rules.d/audit.rules" file:

-a always,exit -F arch=b64 -S init_module,finit_module -F auid>=1000 -F auid!=unset -k module_chng

To load the rule to the kernel immediately, use the following command:

$ sudo augenrules --load

Check Contents

Verify Amazon Linux 2023 is configured to audit the execution of the "init_module" and "finit_module" system calls with the following command:

$ sudo auditctl -l | grep init_module
-a always,exit -F arch=b64 -S init_module,finit_module -F auid>=1000 -F auid!=unset -k module_chng

If audit rule is not defined for the "delete_module" system call, or the line returned is commented out, this is a finding.
