Document Summary
Less destructive than infrastructure attacks; data is altered or destroyed in a system, but physical and virtual systems are still preserved. Virus: piece of code that attaches itself to other instructions within a computer like booting system or application codes. When a user runs those instructions, virus does as well- performs a function and lets user resume control payload and spread. Virus is now in memory and will attach itself to other hosts, execute its. Worms: program that reproduces itself over a computer network. Does not need user to be unleashed- finds computer with vulnerability, carries out attack, then transfers replicated code to next target. Distributed denial of service attacks (data as noise to cover up bandwidth) For example groups like anonymous are classified here. Any set of actions with the intent to compromise inegrity, confidentiality or availability of computer resources. Attacks and release of credit card numbers not for personal gain, but to embarrass.
