• CCI-000169 - The information system provides audit record generation capability for the auditable events defined in AU-2 a. at organization-defined information system components.
• CCI-000130 - The information system generates audit records containing information that establishes what type of event occurred.
• CCI-000172 - The information system generates audit records for the events defined in AU-2 d. with the content defined in AU-3.

Fix Recommendation

Configure the SUSE operating system to generate an audit record for all uses of the "init_module" system call.

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

-a always,exit -F arch=b32 -S init_module -F auid>=1000 -F auid!=4294967295 -k module-load
-a always,exit -F arch=b64 -S init_module -F auid>=1000 -F auid!=4294967295 -k module-load

To reload the rules file, restart the audit daemon

> sudo systemctl restart auditd.service

or issue the following command:

> sudo augenrules --load

Check Contents

Verify the SUSE operating system generates an audit record for all uses of the "init_module" system call.

Check that the system call is being audited by performing the following command:

> sudo auditctl -l | grep -w 'init_module'

-a always,exit -F arch=b32 -S init_module -F auid>=1000 -F auid!=-1 -k module-load
-a always,exit -F arch=b64 -S init_module -F auid>=1000 -F auid!=-1 -k module-load

If both the "b32" and "b64" audit rules are not defined for the "init_module" syscall, this is a finding.

Note:
The "-k" allows for specifying an arbitrary identifier. The string following "-k" does not need to match the example output above.
