Selecting suitable industrial security systems based on current threats

Poster: Towards Selecting Threat Appropriate Industrial Intrusion Detection Systems

Cryptography and Security

Summary

Industrial control systems face many changing cyber threats that need quick and effective responses to keep operations safe. The authors propose a way to share threat information so that the best intrusion detector can be chosen for the specific situation. They tested different detectors on various attacks and found their effectiveness varies a lot depending on the attack type. This shows it could be helpful to pick detectors based on the current threat to improve industrial security.

Abstract

As the threat landscape against industrial control systems is dynamic, effective security requires detection strategies capable of timely reactions to these evolving threat situations. To address this problem, we propose the idea of a counter-threat intelligence sharing based mechanism to select appropriate detectors for current circumstances. To highlight the potential of this mechanism, we conduct attack-level performance evaluations of various intrusion detection systems. Results show the variance of intrusion detection performance depending on the attack scenario, emphasizing the benefits of such a mechanism for industrial control system security
