TIME-3104 - Running NTP daemon

(Time)

This information is provided as part of the Lynis community project. It is related to Lynis control TIME-3104 and should be considered as-is and without guarantees. Any advice and commands should be tested before implementing them in production environments.

Description

Proper time synchronization is important for authentication services, forensics and troubleshooting. Therefore a time daemon (like ntpd) should be running, or a scheduled task to sync time (like ntpdate).

How to solve

Configure a NTP daemon to keep the time in sync with a time server. Most distributions have a "ntp" package available, which can be configured to regularly update the time. If you don't have an internal time server, we suggest to have a look at the ntp.org website, for time servers in your region.
