Remove the systemd_timesyncd Service

An XCCDF Rule

Description

The systemd_timesyncd service should not be installed.

Rationale

Inaccurate time stamps make it more difficult to correlate events and can lead to an inaccurate analysis. Determining the correct time a particular event occurred on a system is critical when conducting forensic analysis and investigating system events. Sources outside the configured acceptable allowance (drift) may be inaccurate.
