A smurf attack depends on misconfigured network equipment that permit packets for being sent to all computer hosts on a selected community by using the broadcast deal with in the network, instead of a selected machine. The attacker will send out huge figures of IP packets Along with the supply tackle faked to seem like the handle on the sufferer.
In the case of a straightforward attack, a firewall can be modified to deny all incoming site visitors in the attackers, according to protocols, ports, or maybe the originating IP addresses. A lot more complicated attacks will even so be really hard to dam with straightforward rules: one example is, if there is an ongoing attack on port 80 (Internet assistance), it is actually not possible to drop all incoming traffic on this port mainly because doing this will prevent the server from getting and serving authentic targeted visitors.
It is significant to observe your site visitors to be familiar with traffic peaks and DDoS attacks.
