Various ICT features are being embedded in an industrial control system (ICS), in accordance with the advancement of information communication devices and an increase in convenience. ICS features and efficiency have been improved through a convergence with ICT technology but they are being exposed to external cyber attacks that take advantage of ICT technology vulnerabilities, and advanced persistent threats attack taking advantage of connectionless devices such as a USB. In particular, malwares that enter infrastructure control system through portable storage device are causing direct/indirect damages to infrastructure and becoming a significant social issue. This paper developed a security patch system for ensuring the stability of a portable storage device data. Specifically, it was designed to create an isolated space for a connectionless device and to execute a selective patch. Based on this study, a safe utilization of infrastructure will be expected.
