Abstract
The psychology and politics of ownership have historically dictated that individuals and groups tend to protect valuable resources. This grew out of the fact that once a resource has been judged to have value, no matter how much protection given to it, there is always a potential that the security provided for the resource will at some point fail. This notion has driven the concept of system security and defined the disciplines of computer and computer network security. Computer network security is made up of three principles: prevention, detection, and response. Although these three are fundamental ingredients of security, most resources have been devoted to detection and prevention because if we are able to detect all security threats and prevent them, then there is no need for response.
