One of the most important issues that network specialists deal with is intrusionanalyzing and defending againstnetwork attacks. Most of the current intrusion detection mechanisms detect and report attacks after they occur, consequently effective protection is impossible. Therefore the issue of Attack Predictionemerges.In network security, it’s prevalent to useGame Theory in order to modelinteraction between attacker and defender, and to select best way of defense.
