What is Brute force attack A Brute force attack such as Smurf attack targets a feature in the IP specification known as directed or subnet broadcasting to quickly flood the target network with useless data A Smurf hacker flood a destination IP address of each packet is the broadcast address of the network the router will broadcast the ICMP echo request packet to all hosts on the network If there are numerous hosts this will create a large amount of ICMP echo request packet the resulting ICMP traffic will not only clog up the intermediary network but will also congest the network of the spoofed source IP address known as the victim network This flood of broadcast traffic consumes all available bandwidth making communications impossible What is IP Spoofing attack Many DoS attacks also use IP Spoofing as part of their attack IP Spoofing may be used to break into systems to hide the hacker s identity or to magnify the effect of the DoS attack IP Spoofing is a technique used to gain unauthorized access to computers by tricking a router or firewall into thinking that the communications are coming from within the trusted network To engage in IP Spoofing a hacker must modify the packet headers so that it appears that the packets originate from a trusted host and should be allowed through the router or firewall What are the default ACL firewall rules in Prestige There are two default ACLs pre configured in the Prestige one allo
