The Oracle Linux operating system must audit all uses of the mount command and syscall.

An XCCDF Rule

Description

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 mount commands. The organization must maintain audit trails in sufficient detail to reconstruct events to determine the cause and impact of compromise. When a user logs on, the auid is set to the uid of the account that is being authenticated. Daemons are not user sessions and have the loginuid set to -1. The auid representation is an unsigned 32-bit integer, which equals 4294967295. The audit system interprets -1, 4294967295, and "unset" in the same way. Satisfies: SRG-OS-000042-GPOS-00020, SRG-OS-000392-GPOS-00172

A Manual Procedure

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!=unset -k privileged-mount
-a always,exit -F arch=b64 -S mount -F auid>=1000 -F auid!=unset -k privileged-mount
