The SYN-Flood attack is currently the most common DDoS attack on the network, It is also the most classic denial of service attack. It takes advantage of a defect in the implementation of TCP protocol. By sending a large number of attack messages with forged source addresses to the ports where the network service is located, it may cause the half-open connection queue in the target server to be full, thus preventing other legitimate users from accessing. This kind of attack was discovered as early as 1996, but it still shows great vitality. Many operating systems, even firewalls and routers, cannot effectively defend against this kind of attack, and it is very difficult to trace it because it can easily forge the source address. Its packet characteristics are usually that the source sends a large number of SYN packets and lacks the last handshake ACK reply of the three handshakes.

I. Introduction to BurpSuite Tools BurpSuite is an integrated platform for attacking web applications. It contains many tools and designs many interfaces for these tools to accelerate the process of attacking applications. All tools share a powerful and extensible framework that can process and display HTTP messages, persistence, authentication, proxies, logs, and alerts. BurpSuite can work efficiently with a single tool, including the following toolkit: Proxy-is a proxy server that intercepts HTTP/S, acting as a middleman between the browser and the target application, allowing you to intercept, view and modify the original data flow in both directions. Spider-is a web crawler that applies intelligent sensing. It can enumerate the content and functions of applications completely. Scanner [Professional only]--An advanced tool that, when executed, automatically discovers security vulnerabilities in web applications. Intruder-is a custom, highly configurable tool that automates attacks on web applications, such as enumerating identifiers, collecting useful data, and using fuzzing techniques to detect generic vulnerabilities. Repeater-is a tool that manually reissues individual HTTP requests and analyzes application responses. Sequencer-is a tool for analyzing unpredictable application session tokens and important data items
