Dos attacks, DDoS attacks, and DrDoS attacks believe that everyone has already heard of it! DOS is the shorthand for denial of service, which is denial of services, and DDoS is the distributed denial of service is the short of distributed denial-of-service, and DrDoS is distributed Reflection denial Abbreviation for service, which is the meaning of distributed reflective denial of service. But the most pow

For application recognition, the data traffic generated is often used for analysis. Packet Capture uses Wireshark to filter sessions and find the key stream when extracting features. The basic syntax of Wireshark filtering is summarized here for future testing. (My mind cannot remember anything) Wireshark can be divided into protocol filtering and content filter

We also need a tool that can read this package, which is the Wireshark to be introduced.Wireshark is an open source tool, and powerful, easy to use, but under the Mac must have X11 to run, directly installed DMG is not able

To make a long story short, Wireshark has a follow TCP stream feature, which is handy. The drawback is that the extracted stream data does not have time stamps and other information, in the analysis of data delay and packet loss is somewhat inadequate. In this case, a simple follow TCP stream function is implemented with Python, while the TCP information is preserved.The principle is simple and is still based on W
