SYSTEM INTRUSION PROCESSES - A SIMULATION-MODEL

In the past few years several break-ins to computer networks and compu ter systems have occurred, and break-ins are becoming more widespread. They may be the acts of external intruders (outsiders), internal intr uders (insiders) or both. More often than not, these intruders attack the system with malicious intent to affect system security attributes, namely secrecy, integrity and service availability. In our paper [1] (Computers & Security, 1995, 14, 621-631) we use a model to present an analytical study of computer system intrusions. This subsequent paper describes a fixed-increment, time-advance, ciscrete-event simulation study of system intrusion processes. The analytical model is subsequen tly used to validate the simulation study. (C) 1997 Elsevier Science L td.
