Exploit Curity

R ecent years have seen an explosive growth of the Internet.

Its explosive growth, flaws in its basic structure, its facilitation of instant access to infor- mation repositories, and its widespread availability has made it increasingly vulnerable. There have been many malicious attempts, or attacks to exploit this vulnerability of the Internet from all over the world; the attacks on the Internet have kept pace with the growth of the Internet.
