Assessment Title

Rule Text

Amazon Linux 2023 must have the chrony package installed.

Description

Discussion Text

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.

How this relates to the STIG checklist: STIG vs SCAP benchmark.

Remediation

Configure Amazon Linux 2023 to have the chrony package installed.

The chrony package can be installed with the following command:
 
$ sudo dnf install -y chrony
