UBTU-16-020380 - Successful/unsuccessful uses of the mount command must generate an audit record - b64

Information

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).

Satisfies: SRG-OS-000037-GPOS-00015, SRG-OS-000042-GPOS-00020, SRG-OS-000062-GPOS-00031, SRG-OS-000392-GPOS-00172, SRG-OS-000462-GPOS-00206, SRG-OS-000471-GPOS-00215

Solution

Configure the operating system to generate audit records when successful/unsuccessful attempts to use the 'mount' command and syscall occur.

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

-a always,exit -F arch=b32 -S mount -F auid>=1000 -F auid!=4294967295 -k privileged-mount
-a always,exit -F arch=b64 -S mount -F auid>=1000 -F auid!=4294967295 -k privileged-mount
-a always,exit -F path=/bin/mount -F auid>=1000 -F auid!=4294967295 -k privileged-mount

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

# sudo systemctl restart auditd.service
