Vulnerability Number

V-279564

Group Title

SRG-OS-000477-GPOS-00222

Rule Version

Fix Recommendation

1. For AOS, configure the audit rules.

$ sudo salt-call state.sls security/CVM/auditCVM

2. For Prism Central, configure the audit rules.

$ sudo salt-call state.sls security/PCVM/auditPCVM

3. For Files, configure the audit rules.

$ sudo salt-call state.sls security/AFS/auditAFS

4. For AHV, configure the audit rules.

$ sudo salt-call state.sls security/KVM/auditKVM

Check Contents

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.
