Objectives: * Identify what Malicious code is * Know the categories of Malicious code * Introduce you to the parts of Malicious software * Know similarities between computer virus and biological virus * Identify the 4 Phases of a Virus * Briefly review the anatomy of a Virus Objectives: * Identify what Malicious code is * Know the categories of Malicious code * Introduce you to the parts of Malicious software * Know similarities between computer virus and biological virus * Identify the 4 Phases of a Virus * Briefly review the anatomy of a Virus

* Modifies or destroys data * Steals data * Allows unauthorized access, * Exploits or damages a system

A Computer Program is designed to achieve a particular function Malicious when the designed to cause adverse effects

Independent: Self contained program that can be scheduled and ran by the operating system Needs Host Program: essential fragments of programs that can not exist independently of some actual application program, utility, or system program

* Trap Doors: Secret entry * Logic Bombs: code embedded in a program * Trojan Horses: security breaking program * Zombies: takes over another internet- attached computer * Viruses: Infects other programs

1. Dormant Phase 3. Triggering Phase 2. Propagation Phase 4. Execution Phase

Virus Structure has four ports 1- Mark can prevent re-infection attempts 2- Infection Mechanism causes spread to other files 3- Trigger are conditions for delivering payload 4- Payload is the possible damage to infected computer
