SLAMMER WORM: THE FASTEST SPREADING BOMBSHELL ON THE INTERNET

What is a computer virus?
Of primary concern is as to what a computer virus is. A virus is a computer program that by your help or by attaching itself to some other program is able to move from one computer to another. Typically these programs are often malicious rather than beneficial even if they have no payload associated with them as they snatch away the system resources. There are several classes of code that fall under the category “virus”. Not all of them are strictly virus in technical terms; some of them are Worms and Trojan horses.
What is a computer worm?
Worms are self replicating programs that do not infect other programs as viruses do; however they create copies of themselves which in turn create copies again, thus hogging the memory resources and clogging the network. Worms are usually seen on networks and multiprocessing OS’s.
What is a Trojan horse?
Trojan Horses are named after the mythical horse that delivered soldiers into the city of Troy. Thus they are programs acting as delivery vehicles; programs that do something undocumented, something that they conceal about at the time of delivery. Thus they disguise their real motive behind some seemingly showy one and ask user to do something at the execution of which some actions are taken which are desperately unwanted by the user.
Slammer Worm: A glance onto the facts.
Slammer (sometimes called Sapphire) was the fastest computer worm in history. As it began spreading throughout the Internet, the worm infected more than 90 percent of vulnerable hosts within 10 minutes, causing significant disruption to financial, transportation, and government institutions and precluding any human-based response. In this seminar, I wish to describe how it achieved its rapid growth, dissect portions of the worm to study some of its flaws, and look at the defensive effectiveness against it and its
