OL 9 must have the chrony package installed.

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.

Verify that OL 9 has the chrony package installed with the following command:

$ dnf list --installed chrony Installed Packages chrony.x86_64 4.5-1.0.2.el9 @ol9_baseos_latest

If the chrony package is not installed, this is a finding.

Install the chrony package with the following command:

$ sudo dnf install -y chrony
