Principles and defense methods of SYN flood Network Attacks Summary This paper introduces the basic principles of SYN Flood attacks, and describes in detail several effective defense measures: SYN-cookie technology and address status monitoring technology. 1 SYN Flood attack introduction: Denial of Service (DoS) is an effective and very difficult way to defend against, it aims to prevent the server from pr

Summary The author directly witnessed a hacker attack led by the hacker organization Anonymous. Here we mainly describe the main attack weapons they use and some countermeasures. One reason for hacking to gain greater visibility recently is that it is now easy to get and use attack tools, especially in DoS attacks. Hackers usually aim to protest or contribute to a special political issue, but these days everyone becomes the target of an attack, even i

Editor: a publicity draft From the beginning to the present, ARP attacks are everywhere, and LAN attacks are always prone to ARP attacks. For protection against ARP attacks, choose "two-way binding"> "one-way binding"> "loop binding"> "ARP locating interception". There are also a lot of ARP protection software in the

This article is provided by the famous German hacker Mixter (only 20 years old) who compiled Distributed Denial-of-Service attack tools TFN and TFN2K (these tools were used to attack large websites such as Yahoo. To put it simply, it is very complicated to master all the causes and security vulnerabilities that may cause intrusion and be used to launch DoS attacks. In detail, there is no simple or dedicated way to protect against these

IntroductionROP (return-oriented programming), or "return-oriented programming technology". The core idea is to find a suitable instruction fragment (gadget) in the existing function in the whole process space, and to splice each gadget through a well-designed return stack to achieve the purpose of malicious attack. The difficulty with constructing ROP attacks is that we need to search the entire process space for the gadgets we need, which can take a
