Before studying this issue, let's talk about DDOS: What is DDOS: DDoS (Distributed Denial of Service) attacks are simple and fatal network attacks by exploiting TCP/IP protocol vulnerabilities. Due to the session mechanism vulnerabilities of TCP/IP protocol, therefore, there is no direct and effective defense means. A large number of instances prove that the use

prevent legitimate users from accessing the normal network resources, so as to achieve the ulterior motives of the attackers. Although the same denial of service attack, however, DDoS and DOS are still different, DDoS attack strategy focused on many "zombie host" (by the attacker or indirect use of the host) to the victim host to send a large number of seemingly

1. Why DDoS attacks?With the increase in Internet bandwidth and the continuous release of a variety of DDoS hacking tools, DDoS denial-of-service attacks are becoming more and more prone, and DDoS attacks are on the rise. Due to business competition, retaliation, network extortion, and other factors, many network servi

In particular, for some large enterprises, their main businesses are accumulated in servers. If the servers are attacked, the loss of important information or con

DDoS (Distributed denial of service) attack is a simple and fatal network attack using TCP/IP protocol vulnerability, because the TCP/IP protocol is unable to modify the session mechanism, so it lacks a direct and effective defense method. A large number of examples prove that the use of traditional equipment passive defense is basically futile, and the existing firewall equipment will be paralyzed due to limited processing capacity, become a network

recently took a little time to "the King of Destruction-ddos attack and the depth of the prevention of the analysis" to read it, frankly, this book is relatively simple, can be said to be an introductory book, of course, for me this kind of DDoS smattering people, is also a good book, at least I learned something. DDoS is a shorthand for distributed denial-of-ser

How to solve the problems of switch DDoS attacks and Intranet server DDoS attacks Those who have experience in Internet cafes or data center management must know that computer viruses are a headache, especially intranet server DDoS attacks and switch DDoS attacks, which directly affect the security of Internet cafes,

1. Overview With the development of information technology, various network security problems are emerging. Although WLAN has the advantages of easy to expand, flexible to use and economical, it is particularly vulnerable to the security aspect because of its use of RF working mode. The wireless network based on ieee802.1l has been widely used, but it has also become an attractive target. Due to the serious defects of IEEE802.11 's WEP encryption mechanism and authentication protocol, a series

To go to the bank to do business examples:Network layer DDoS is to let the road to the bank become congested, unable to get the people who really want to go to the bank, often use the protocol as a network layer, such as TCP (using three handshake response to wait and limit the number of computer TCP connections), etc.The application layer DDoS is to consume the bank's business resources, such as using HTTP

Ddos (Distributed Denial of Service), commonly known as flood attacks. It is a new and more destructive attack method based on traditional DoS attacks. Distributed Denial of Service (DoS) attacks refer to the combination of multiple or even hundreds of thousands of computers as attack platforms by means of the customer/server technology to launch DoS attacks against one or more targets, this improves the attack power exponentially. The damage caused b

In linux, the most common way to defend against ddos attacks is to install DDoS deflate to prevent or mitigate ddos attacks. However, there are other methods to use. I will introduce them below. Introduction to DDoS deflate DDoS d

content of the site is the ISP (Network service provider) and WiFi provider's usual profit means.For example, some hotel networks, mobile networks will insert ads or other tracking cookies into the websites that users visit. Legitimate business typically does not inject malicious code into the site, but it does not mean that others on the Internet are not able to do so. If an attacker can obtain network location privileges like ISPs, such as network interconnection and switching nodes, an attac

As a powerful hacker attack method, DDoS is a kind of special denial of service attack. As a distributed, collaborative, large-scale attack, it often locks victim targets on large Internet sites, such as commercial companies, search engines, or government department sites. Because of the bad nature of DDoS attacks (often through the use of a group of controlled network terminals to a common port to launch a
