What is DDos attack

DDoS attack

Distributed denial of service (DDoS) attacks vary from regular denial of service (DoS) attacks due mainly to the extra “D,” which stands for “distributed.” Typically, a DDoS attack is launched from many machines which are generally PC’s that have been infected with a virus or trojan allowing them to be controlled by a “bot herder,” who gathers the infected machines into a single collective. An attacker can then issue commands to the collective, transparently ordering the machines to attack a specific target.
