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.Synchronizing internal information system clocks provides uniformity of time stamps for information systems with multiple system clocks and systems connected over a network. Organizations should consider setting time periods for different types of systems (e.g., financial, legal, or mission-critical systems).Organizations should also consider endpoints that may not have regular access to the authoritative time server (e.g., mobile, teleworking, and tactical endpoints). This requirement is related to the comparison done every 24 hours in SRG-OS-000355 because a comparison must be done in order to determine the time difference.

Check content

Run the following command to determine the current status of the "ntpd" service: # service ntp status If the service is configured, the command should show a list of the ntp servers and the status of the synchronization. If it does not, this is a finding.

Fix text

The "ntp" service can be enabled with the following command: # chkconfig ntp on # service ntp start Configure the time server for the authoritative time source with the following steps: 1. Edit /etc/ntp.conf and locate the "server" entry. 2. Replace the address with the address of the authoritative time source. 3. Save the /etc/ntp.conf file. 4. Restart the ntp daemon with /etc/init.d/ntp start.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
