In computer security a denial-of-service attack (DoS attack) is a computer crime that violates the Internet proper use policy as indicated by the Internet Architecture Board (IAB) and makes a computer resource unavailable to its intended users.
DoS attacks have two general forms:
- Make the victim computer(s) to reset or consume its resources such that it can no longer provide its intended service.
- Obstruct the comunication media between the intended users and the victim in such that they can no longer communicate adequately.
Methods of attack
Attacks can be directed at any network device, including attacks on routing devices and Web, electronic mail, or Domain Name System servers. More on [ Denial-of-service attack ]
