The data capture mainly gathers the data from the network. Protocol analysis can analyse every segment of the data packet according to protocol standard. Data recover can recover all the data of the application layer of the TCP connection. IP spoofing can construct all kinds of packets and realize the network attack. Real-time interruption can interrupt the TCP connection of Both sides of communication as the third party. Fire wall can realize network access control. Then the system can protect the network information safety from many aspects.

数据捕获主要完成从网络采集数据的功能；分析还原包括协议分析和数据还原两部分内容，协议分析可以对捕获到的数据包按照网络协议规范分别进行各协议字段分析，数据还原功能可以将每条TCP连接中传输的所有应用数据进行重新组合，还原出原来数据的内容；IP欺骗指构造各种功能的数据包，实现网络攻击；实时阻断指第三方实时阻断通信双方的TCP连接，禁止他们进行数据通信；防火墙主要实现网络访问控制，保护内部子网的功能。
