In TCP protocol, messages arriving at the destination will enter the buffer of the TCP stack and will not be forwarded to the receiving system until the buffer is full. This is to minimize the number of times the system empties the buffer. However, the sender can force the receiving system to clear the contents of the buffer by sending a TCP message with a PSH flag of 1. The TCP PUSH + ACK attack, like the TCP SYN attack, aims to deplete the resources of the victim system. When an attacker sends TCP messages with PSH and ACK flags set to 1 to the Target host, these messages will cause the Target system to clear all TCP buffers (whether the buffers are full or not) and respond with an acknowledgement message. If this process is performed by a large number of controlled hosts, the system will not be able to process normal data, resulting in denial of service.

1. Introduction to Publish and Subscribe Mode
When the SYN gateway receives the SYN packet from the client, it directly forwards it to the server. After receiving the SYN/ACK packet from the server, the SYN gateway forwards the packet to the client and sends the ACK confirmation packet to the server in the name of the client. At this time, the server enters the connected state from the semi-connected state. When the client confirms the arrival of the packet, it forwards if there is data, otherwise it discards it. In fact, the server has a connection queue in addition to maintaining the semi-connection queue. If SYN attack occurs, the number of connection queues will increase, but the number of connections that the general server can withstand is much larger than the number of semi-connections, so this method can effectively reduce the attack on the server.

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

LINUX: Linux uses the variable tcp_max_syn_backlog to define the maximum half number of connections that the backlog queue can hold. In Redhat 7.3, the value of this variable defaults to 256, which is far from enough. A low-intensity SYN attack can fill up the half-connection queue. We can modify the value of this variable with the following command:
