Summary: | 碩士 === 國立雲林科技大學 === 資訊管理系 === 107 === Industrial Control Systems (ICS) are widely used in critical infrastructure around the world to provide services that sustain people's livelihoods and economic operations, so security is important for these critical infrastructures. The security of ICS is still insufficient, and it will cause a certain degree of damage once it is attacked or intruded. ICS has been designed in a closed network in the past, so industrial facilities and transmission protocols lack security verification, and ICS's high requirements for availability make the facilities in ICS rarely replaced and upgraded. In recent years, in order to understand the real-time information of production, the company connects the ICS network with the company's internal network, making the company's network a way for attackers to enter ICS.In the past, although many scholars have proposed defense methods for ICS, but there is still a lack of testing tools for verifying these defense methods. The purpose of this study is to develop a security test system for ICS, using the currently theoreticalized Modbus attack method to test ICS security. It is expected that future related research will focus more on the development of defense methods to improve the security of ICS.
