Information

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

GROUP ID: V-234935
RULE ID: SV-234935r958412

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
