AI Technical Summary
Existing network security protection solutions fail to detect attack behavior in the first session of a TCP connection due to resource limitations, leading to missed detections and compromised security when using the proxy mode.
The method involves quickly switching to the proxy mode by identifying the application layer protocol in the first session, performing security detection on subsequent packets, and managing packet transmission to ensure all traffic is fully detected, even in the first session, thereby avoiding missed attacks.
This approach ensures comprehensive security detection, reduces resource consumption, and improves detection performance by enabling the proxy mode for critical sessions, preventing threats from being overlooked.
