Fix Recommendation

Configure the operating system to generate audit records when successful/unsuccessful attempts to use the "init_module" syscall occur.

Add or update the following rules in "/etc/audit/rules.d/audit.rules":

Note: The rules are duplicated to cover both 32-bit and 64-bit architectures. Only the lines appropriate for the system architecture must be configured.

-a always,exit -F arch=b32 -S init_module -k module-change

-a always,exit -F arch=b64 -S init_module -k module-change

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

Check Contents

Verify the operating system generates audit records when successful/unsuccessful attempts to use the "init_module" syscall occur.

Check the auditing rules in "/etc/audit/audit.rules" with the following command:

Note: The output lines of the command are duplicated to cover both 32-bit and 64-bit architectures. Only the line appropriate for the system architecture must be present.

# grep -iw init_module /etc/audit/audit.rules

-a always,exit -F arch=b32 -S init_module -k module-change

-a always,exit -F arch=b64 -S init_module -k module-change

If there are no audit rules defined for "init_module", this is a finding.
