VPN Traffic Detection Based on Behavioral Characteristics
摘要
In recent years, with the continuous advancement of network technologies, the encryption mechanisms of VPNs have become increasingly complex, rendering traditional traffic identification methods progressively ineffective. Conventional approaches based on port numbers and protocol characteristics are no longer sufficient to cope with the variability and encryption features of modern VPNs. Therefore, exploring how to accurately identify VPN servers through network traffic characteristics has become a critical issue in the field of cybersecurity. Identifying VPN servers through traffic analysis not only enables network security administrators to better manage network resources but also provides strong technical support for the secure operation of networks.
