Adjusting Global Settings

DDoS Hybrid Defender™ uses reasonable default settings for the global system settings. Some environments may require adjustments to port numbers, allowed protocols, or thresholds that signal an attack. For example, you may use a different DNS or SIP port number from the one that is configured. In that case, you can change it.

Many of the thresholds indicate the value at which a packet, header, URI, or other setting is considered too large, too small, or not typical. This does not necessarily indicate an attack. It means that the value is unusual enough that you should take a look at what's happening on the system. You may want to change the global settings because the traffic should be allowed and should not cause alarm.

However, note that adjusting these settings should be needed only in rare cases. The changes should be made only by an administrator familiar with the applications, servers, or other network objects that DDoS Hybrid Defender is protecting.
