Please note that the NTP client is disabled by default in SIMA2 2. In case you must use the NTP server on an SIMA2, choose from the following options to reduce NTP-based risks: - Allow NTP traffic to/from trusted NTP clients only - Monitor the network for malicious NTP traffic going to/coming from the SIMA2 - Filter malicious NTP traffic going to/coming from the SIMA2 Monitor NTP server operations on your SIMA2 (server availability, correctness of advertised time, NTP-related log entries, etc.) 3.
