Anti-DoS attack
The following functions are available to defend against DoS attacks:
SYN defence: When activated, the system discards SYN flood messages to counteract overload.
ICMP defence: The system detects unusually high amounts of ICMP packets and filters them so that
an overload is avoided.
Note: Activating the functions requires system performance and affects, among other things, the real-
time capability of the system.
Sync Time Whitelist
If the Sync-Time Whitelist is activated, time synchronisation only takes place with the listed devices.
Click on "Add" to add a device per IP or devices per IP circle to the list.
