Select a well-known virus or malicious code attack, and prepare a summary report describeing what kind of malicious attack it was, how it spread and attacked other devices, and how it was mitigated. Indicate how you would defend the attack from recurring on a network you control. You may use the Internet for research.

Consider the following:

The severity of the outbreak
The propagation methods and speed
The targets of the attack
The success rate of the attack vector
Additional complexity: self-armoring, self-updating, and so on
The ways to defend infection in every domain
The ways to defend intrusion at every layer
