Electronic elements of a substation control system have been recognized as critical cyber assets ... more Electronic elements of a substation control system have been recognized as critical cyber assets due to increasingly complex automation system that is further integrated with physical facilities. As this can be executed by unauthorized users, the security investment of cyber systems remains one of the most important factors for substation planning and maintenance. As a result of these integrated systems, intrusion attacks can impact operations. This work is to systematically investigate the intrusion resilience of the ten architectures between a substation network and others. In this paper, two network architectures comparing computer-based boundary protection and firewalldedicated virtual local area networks (VLANs) are detailed, i.e., architectures one and ten. A comparison on the remaining eight architecture models was performed. Mean time to compromise (MTTC) are used to determine the system operational period. Simulation cases have been set up with the metrics based on different levels of attackers' strength. These results as well as sensitivity analysis show that implementing certain architectures would enhance substation network security.
