SLES-15-030360 - The SUSE operating system must generate audit records for all uses of the umount system call.

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 of the "umount" and "umount2" system calls.

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

To reload the rules file, restart the audit daemon

> sudo systemctl restart auditd.service

or issue the following command:

> sudo augenrules --load
