Security: Attacks Exposed

How serious a particular attack type is depends on two things: how the attack is carried out, and what damage is done to the compromised system. An attacker being able to run code on his machine is probably the most serious kind of attack for a home user. For an e-commerce company, a denial of service (DoS) attack or information leakage may be of more immediate concern. Each vulnerability that can lead to compromise can be traced to a particular category, or class, of attack.The properties of each class give you a rough feel for how serious an attack in that class is, as well as how hard it is to defend against. In this article, we explain each of the attack classes in detail, including what kinds of damage they can cause the victim, as well as what the attacker can gain by using them.
