Vulnerability Discussion

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.

Check

The chrony package can be installed with the following command:

$ sudo dnf install chrony

Fix

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

$ sudo dnf list --installed chrony

Example output:

chrony.x86_64 4.1-3.el9

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