Network Vulnerability Analysis and Strengthening Strategy of Substation Monitoring System
Through experimental research,this paper evaluates the performance of Scapy framework in detecting network vulnerabilities and combining Advanced Encryption Standard(AES)and RSA encryption algorithm to protect the mixed encryption and decryption of General Object Oriented Substation Event(GOOSE)messages.The experiment successfully found and recorded a variety of network vulnerabilities in different degrees,and verified the accuracy and adaptability of Scapy framework.At the same time,the experimental results prove that the encryption and decryption scheme can effectively protect the communication content,and has little impact on the performance in the actual communication scenario.The comprehensive experimental results show that the scheme has certain practical application potential in substation monitoring system and provides a feasible solution for network vulnerability protection.
