It is all about the packet. After a packet is on the network wire, someone or something
somewhere has to either deliver or drop the packet.
In the context of an intrusion or attack, the question is who will drop the packet and where will the packet be
dropped?
Chapter 7. Attack Vectors and Mitigation Techniques
One of the biggest problems in network security today is that network managers think of security as something
to implement after a network is designed. Security, therefore, tends to be an afterthought at best and, in most
cases, is often forgotten completely. This has led to many insecure network designs and solutions.
An attack vector is a vulnerability, exploit, or mode that is open to abuse. Vulnerabilities, threats, and exploits
lead to network attacks and are problems that have no easy solution, mainly because they are native to the
design of the TCP/IP suite. Understanding how and why these attacks are launched, coupled with the proactive
prevention mechanisms, can help you protect the network from these malicious cloaking and cracking
techniques.
Effective mitigation of such attacks is an especially pressing problem on the Internet, and experts have
researched and proposed various methods to prevent them.
