Attack Resilient Cloud-Based Control Systems for Industry 4.0

Abstract

In recent years, since the cloud can provide tremendous advantages regarding storage and computing resources, the industry has been motivated to move industrial control systems to the cloud. However, the cloud also introduces significant security challenges since moving control systems to the cloud can enable attackers to infiltrate the system and establish an attack that can lead to damages and disruptions with potentially catastrophic consequences. Therefore, some security measures are necessary to detect these attacks in a timely manner and mitigate their impact. In this paper, we propose a security framework for cloud control systems that makes them resilient against attacks. This framework includes three steps: attack detection, attack isolation, and attack mitigation. We validate our proposed framework on a real testbed and evaluate its capability by subjecting it to a set of attacks. We show that our proposed solution can detect an attack in a timely manner and keep the plant stable, with high performance during the attack.

Performance Evaluation of QUIC Vs. TCP for Cloud Control Systems

“…Based on our previous study on CCSs [15], [16], where HTTP1.1 was mainly implemented in the systems, the payload size containing the plant state or control signal is typically small, ranging from 200-300 bytes. This is much smaller compared to payload sizes of web page or video downloads.…”
