Construction and Evaluation of Defense-in-Depth architecture in SCADA System

Abstract

The increasing use of common computer technologies in SCADA systems has brought convenience and at the same time introduced unprecedented security threats. SCADA system is becoming an attacker's target day by day. As attackers gain more understanding of industrial control systems, attacker's attack methods are more and more sophisticated, and the attack intensity is also increasing day by day. Faced with many security threats and risks, traditional security precautions cannot be effectively implemented. Therefore, this paper proposes an improved SCADA defense system, and evaluates it by using a variety of attacks. Experiments show that the defense-in-depth model we proposed is very effective against a variety of attacks.
