Vulnerability Discussion

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).

Check

Verify OL 8 enables Linux audit logging of the USBGuard daemon with the following commands.

Note: If the USBGuard daemon is not installed and enabled, this requirement is not applicable.

$ sudo grep -i auditbackend /etc/usbguard/usbguard-daemon.conf

AuditBackend=LinuxAudit

If the "AuditBackend" entry does not equal "LinuxAudit", is missing, or the line is commented out, this is a finding.

Fix

Configure OL 8 to enable Linux audit logging of the USBGuard daemon by adding or modifying the following line in "/etc/usbguard/usbguard-daemon.conf":

AuditBackend=LinuxAudit
