  • FixedSIMA² Master Stationauma_psirt

    Upgrade your SIMA2 to software version 2.6 or above. The NTP service of the SIMA2 Master Station with software version V2.6 and above includes a current, supported version of ntpd.

  • MitigationSIMA² Master Stationauma_psirt

    1. If your SIMA2 does not need to provide time information to other systems or synchronize itself with an NTP server, disable the NTP client on those systems. 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. In case you must use the NTP client on an SIMA2, choose from the following options to reduce NTP-based risks: - Use trusted NTP servers only - Allow NTP traffic to/from trusted NTP servers only - Monitor the network for malicious NTP traffic targeting the SIMA2 - Filter malicious NTP traffic targeting the SIMA2 - Monitor NTP client operations on your SIMA2 (correctness of system time, NTP-related log entries, etc.)
