Nutanix OS must generate audit records for all kernel module load, unload, and restart actions, and also for all program initiations.
Overview
| Finding ID | Version | Rule ID | IA Controls | Severity |

| Description | ||||
| 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). | ||||

1. Verify Nutanix OS generates audit records for all kernel module load, unload, restart actions, and initiations using the following commands.
$ sudo grep -iw create_module /etc/audit/audit.rules
-a always,exit -F arch=b32 -S create_module -k module-change
-a always,exit -F arch=b64 -S create_module -k module-change
$ sudo grep -iw init_module /etc/audit/audit.rules
-a always,exit -F arch=b64 -S init_module -S delete_module -k modules
-a always,exit -F arch=b32 -S init_module -S delete_module -k modules
$ sudo grep -iw finit_module /etc/audit/audit.rules
-a always,exit -F arch=b32 -S finit_module -k module-change
-a always,exit -F arch=b64 -S finit_module -k module-change
$ sudo grep -iw delete_module /etc/audit/audit.rules
-a always,exit -F arch=b64 -S init_module -S delete_module -k modules
-a always,exit -F arch=b32 -S init_module -S delete_module -k modules
If both the "b32" and "b64" audit rules are not defined for the module(s) listed syscall, this is a finding.
2. Run the command:
$ sudo grep -iw kmod /etc/audit/audit.rules
-w /usr/bin/kmod -p x -F auid!=unset -k module-change
If the command does not return any output, this is a finding.
