� TCP Port Scan � UDP Port Scan � Incoming rules � Incoming IP protocol rule � Outgoing rules � Buttons to manage the rules ICMP protocol Reference: Configuration options The Internet Control Message Protocol (ICMP) is used to exchange error and information messages on networks. The protocol is also used for status messages with ping or tracer. With this rule, you can define the incoming and outgoing blocked message types, the behavior in case of flooding and the reaction to fragmented ICMP packets. This rule serves for preventing so-called ICMP flood attacks, which results in an increase of the CPU load of the attacked machine as it responds to every packet. Predefined rules for the ICMP protocol Setting Rules Low Incoming blocked types: no type. Outgoing blocked types: no type. Assume flooding if delay between packets is less than 50 ms. Reject fragmented ICMP packets. Medium Same rule as for the low level. High Incoming blocked types: several types Outgoing blocked types: several types Assume flooding if delay between packets is less than 50 ms. Reject fragmented ICMP packets. Incoming blocked types: no types/several types With a mouse click on the link a list of ICMP packet types is displayed. From this list you can specify the desired incoming ICMP message types you want to block. Avira Professional Security - User Manual (Status: 30 Mar. 2012) 145
