“…The models for cyber security (malicious attacks initiated on the cyber infrastructure) are presented in [17]. The most common analytical method applied to cyber security threat models is the concept of the attack tree [18]. Attack trees work backwards from a goal that the attacker wishes to achieve, by identifying steps that lead to that goal.…”

“…To better represent the characteristics of cyber networks, a benchmark testbed with technical details on substation configuration, switch topology, and control scheme is needed. 10 To the best of our knowledge, such a testbed is not available. This creates the burden of developing a small and customized testbed whenever a new methodology is proposed.…”

Summary The functioning of communication and control networks inevitably impacts the reliability of power systems. However, due to the complex cyber‐power interdependencies and the unavailability of a benchmark testbed, developing feasible and effective models that incorporate the impact of cyber system failures on power systems is challenging in reliability studies. In this paper, we propose the framework of a benchmark testbed by extending the IEEE Reliability Test System (RTS) 79 with cyber configurations. A comprehensive methodology to model intra and inter substation malfunctions is also presented to quantitatively compute the impact of cyber failures on composite power system reliability. System‐wide reliability indices, such as the loss of load expectation and the expected energy not supplied, are obtained. Simulation results demonstrate that power system reliability is degraded due to cyber malfunctions. Furthermore, the extension of the IEEE RTS 79 with information and communication technology specifications provides a benchmark tool for researchers in future cyber‐physical reliability studies.

“…The vulnerability of the networked control system has been widely studied and discussed by both academia and industry, mainly including: information management vulnerability [9], operating system and database vulnerability [10,11], embedded control device vulnerability [11][12][13], and industrial communication protocol vulnerability [14][15][16]. As the major communication carrier for different industrial control devices, the industrial communication protocols are always utilized by malicious hackers as a breakout to perform various attacks.…”

Content-based deep communication control for networked control system

In smart cities, the networked control system plays a significant role in transportation systems, power stations or other critical infrastructures, and it is facing many security issues. From this point, this paper proposes a content-based deep communication control approach to guarantee its security. Based on the layer architecture, this approach analyzes the interactive content in depth according to different industrial communication protocols, and implements the access control between two distinct enclaves. For OPC Classic, we acquire the dynamic port provided by OPC server, and open a new connection belonging to this port; for Modbus/TCP, we not only analyze the ordinary function codes and addresses, but also check the register or coil values by using the multi-bit Trie-tree matching algorithm. Besides, the white-listing strategy is introduced to satisfy the special requirements of industrial communication. Our experiment results show that, on the one hand the proposed approach pro- vides OPC and Modbus/TCP defenses in depth; on the other hand it has less than 1 ms forwarding latency and 0 packet loss rate when the rule number reaches 200, and all these meet the availability requirements in the networked control system. In particular, this approach has been successfully applied in several real-world petrochemical control systems.
