Explanation
A Denial-of-Service (DoS) attack is an attack meant to shut down a machine or network, making it inaccessible to its intended users. DoS attacks accomplish this by flooding the target with traffic, or sending it information that triggers a crash. In both instances, the DoS attack deprives legitimate users (i.e. employees, members, or account holders) of the service or resource they Denial of Service Attacks can take many forms. The most important ones are: SYN flood - SYN flood attacks send requests to connect to a server but don’t complete the handshake. The end result is that the network becomes inundated with connection requests that prevent anyone from connecting to the network. Teardrop Attack - During a teardrop DoS attack, an attacker sends IP data packet fragments to a network. The network then attempts to recompile these fragments into their original packets. The process of compiling these fragments exhausts the system and it ends up crashing. It crashes because the fields are designed to confuse the system so that it can not put them back together.
