- Abstract
- Although existing control systems have been developed and operated independently, the development of information technology has made access to control systems easier. Note, however, that such advancement of control systems gave rise to many security vulnerabilities; thus, the threat of cyber-attack is increasing as well. Since availability is the most critical factor in a control system, independent network security technology is most appropriate. The leading security device in such form is the firewall system. Therefore, this paper discusses the design and application of the IndusCAP-Gate (Industrial Cyber Attack Prevention?? Gate) system, an industrial firewall system that fundamentally prevents unauthorized access to a control system. It applies access control filters of various levels to provide flexible and clear access control functionality. Most of all, the proposed system?봴nlike an IT firewall that implements access control to an unspecified mass?봦as a structure that facilitates the provision of security policy specific to each zone of the control system intranet used for access control of the specific system and service.
