Time

All Security Management Servers, Security Gateways, and Cluster Members must synchronize their system clocks.

This is important for these reasons:

• SIC trust can fail if devices are not synchronized correctly.

• Cluster synchronization requires precise clock synchronization between members.

• SmartEvent Correlation uses time stamps that must be synchronized to approximately one a second.

• To make sure that cron jobs run at the correct time.

• To do certificate validation for applications based on the correct time.

You can use these methods to set the system date and time:

• Network Time Protocol (NTP).

• Manually, in the Gaia Portal, or Gaia Clish.

Network Time Protocol (NTP)

NTP runs as a background client program on a client computer. It sends periodic time requests to specified servers to synchronize the client computer clock.

Best Practice - Configure more than one NTP server for redundancy.
