Abstract: With the deep integration of Internet technology, the automation and intelligent construction of power systems are becoming more perfect. It can not only monitor the entire power network in real time, but also detect faults and make corresponding decisions and treatments. However, it also induced many privacy leaks and malicious attacks. Vulnerability detection of transformer substation hosts has become the top priority of the entire power grid system. This paper designed a vulnerability detection system for transformer substation hosts based on port scanning. It used TCP/UDP connection to detect the open status of the port, and used third-party tools to detect whether there are potential or existing vulnerabilities in the open port service. The main method is to test the response of the port by simulating attack and then compare it with the existing vulnerability database, and finally generate a vulnerability scanning report in HTML format. Experiments have verified the availability and robustness of the system.
