Abstract
Description
technical field
[0001] The invention belongs to the technical field of network data packet analysis, and in particular relates to a method for monitoring a WEB service of a server protection device in a bypass mode. Background technique
[0002] Common network monitoring modes can be divided into two types: one is serial monitoring mode, and the other is bypass monitoring mode. The series mode is generally monitored through the mode of gateway, bridge or proxy server. Since the monitoring device is used as a gateway or bridge in the network connected in series, all data must first pass through the monitoring system, and only after the analysis and inspection of the monitoring system. It can be sent to each client, so there will be a certain delay in the network speed. Bypass monitoring mode refers to monitoring through the port mirroring function of network devices such as switches. In this mode, the monitoring device only needs to be connected to the designated mirroring p...

Embodiment
[0017] Such as figure 1 As shown, the client establishes a virtual connection process diagram with the Apache server, which specifically includes the following steps:
[0018] Step 101: The client sends a TCP SYN (s=100, a=0) request to the WEB server, and the request enters a switch with a mirror port, and the mirror port copies a copy of the data and sends it to the server protection device.
[0019] Step 102: The server protection device judges whether the packet destination address of the SYN request is the protected WEB server address, and if so, modifies the destination address and port of the SYN request packet to be the address and port of the Apache server.
[0020] Step 103: After the Apache server receives the SYN request packet, the first handshake is successful, and replies with a SYN-ACK packet, adding a seq value of 500 to the packet and sending it to the server protection device.
[0021] Step 104: The server protection device records the data packet and does ...
