A denial-of-service attack is an attack in which a company is deprived of its network/computer application or connection resources. The most common kind of denial-of-service attack is when the bad guys simply send more data traffic to a network Web site than its data buffers can handle. This may result in slower computers. Other times computers may crash outright. For example, a Web site accessed by millions of hits can be forced to temporarily cease operation.
This attack often can morph into a "distributed" threat, a distributed denial-of-service attack when the attacker's Bot network can number in the tens of thousands of slave computers, and are located anywhere in the world. Such an attack is harder to defend against because security firewalls need to be strong enough to decipher valuable data traffic--customer orders, for example--from malicious data. Herein lies the problem.
