Design and Research of Network Security System Based on Unknown Application Layer Protocol Identification Method
With the explosive growth of network traffic,identifying unknown application layer protocols and managing network security have become an urgent problem to be solved.Therefore,in order to improve the accuracy and efficiency of protocol recognition,this article studied unknown application layer protocols,classified protocol loads at multiple levels,and used slid-ing window technology to segment the same group of data to improve data processing efficiency and accuracy.In terms of fea-ture extraction,this study innovatively employed the GramMatch algorithm to address changes in protocol transmission ports.The results show that after the protocol transmission port is modified,the recognition rate of the GramMatch algorithm only decreases by 0.14％,demonstrating its higher robustness.At the same time,the recognition rate of traditional nDPI technolo-gy significantly decreases by 75.52％in similar tests.In summary,this study not only demonstrates the effectiveness of net-work security system design based on unknown application protocol recognition methods,but also demonstrates excellent rec-ognition performance in practical applications.
