A Framework of Cyber-Security Protection for Warship Systems

Warship systems which belong to cyber-physical systems (CPSs) are facing severe cyber security challenges with the adoption of large amount of Information Technology. Security events happened in warship systems can cause serious consequences, such as death of person, destruction of warship and even the failure of the war, which are quite different from IT systems. This paper proposes a comprehensive resilient security protection framework which combines static security protection and dynamic security protection after analyzing warship systems security situation. In the framework, some prevention and isolation techniques are used for static protection to reinforce the security, and a close-loop based security protection with ability of intrusion tolerance is achieved for dynamic protection to realize active defense. This framework contributes to warship security design for designers and promote warship cyber security against cyber attacks.
