SLES-12-020300 - The SUSE operating system must generate audit records for all uses of the umount command.

Information

Reconstruction of harmful events or forensic analysis is not possible if audit records do not contain enough information.

At a minimum, the organization must audit the full-text recording of privileged commands. The organization must maintain audit trails in sufficient detail to reconstruct events to determine the cause and impact of compromise.

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

Solution

Configure the SUSE operating system to generate an audit record for all uses the 'umount' command.

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

-a always,exit -F arch=b32 -S umount -F auid>=1000 -F auid!=4294967295 -k privileged-umount
-a always,exit -F arch=b32 -S umount2 -F auid>=1000 -F auid!=4294967295 -k privileged-umount
-a always,exit -F arch=b64 -S umount2 -F auid>=1000 -F auid!=4294967295 -k privileged-umount

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

# sudo systemctl restart auditd.service
