基于HTTP协议的POST请求的文档传输渠道有很多,传送的具体文档格式更是千变万化,但是其传输过程是一样的。通过对各种POST数据格式通信特征的分析,提出了一种在Linux平台下的数据包分析与还原模块,具体针对各种数据格式归纳总结出其各自的特征,形成特征库,然后借助于现有的网络安全开发包,实现对网络上以POST方式传输的信息的实时捕获、分析与还原,再辅之以文本内容查询子模块,从而实现对网络传输信息监管能力的促进与提高。
There are many document transmission channels for HTTP requests based on the HTTP protocol. The format of the specific document transmitted is ever-changing, but the transmission process is the same. Based on the analysis of communication features of various POST data formats, a data packet analysis and reduction module based on Linux platform is proposed. The specific characteristics of each data format are summarized, and the feature database is formed. Some network security development kits enable the real-time capture, analysis and restoration of information transmitted via the network on a POST basis, and the sub-modules of text content inquiry, so as to promote and improve the information supervision capability of network transmission.
