At the beginning of this year, a piece of news entitled "8848 was under DDoS attack and suspected to be attacked by Baidu" attracted wide attention from users. In addition to the well-known enterprises on the Internet, the word "DDoS" has attracted the attention of the media and users. Today, we have a deep understanding of DDoS attacks and defense against indivi
First Look at DDoS:
Distributed denial of service (ddos:distributed denial of services) attack refers to the use of client/server technology to unite multiple computers as an attack platform to launch a DDoS attack on one or more targets, thereby multiplying the power of a denial of service attack. Typically, an attacker would use a theft account to install a DDoS
This topic is the content we shared in the OWASP Hangzhou region security salon at the end of 2013. Here we resummarized the overall content of this topic and formed a text version.
In this article, the case and response experience of DDoS come from the actual scenarios of a customer service system with a high market share, we analyze the costs, efficiency, and specific architecture design (selection, configuration, and optimization) to cope with diff
Welcome to subscribe to the public number: Python from the program Ape to the programmer.If you do not know can add: 49130.8659, code: Cauchy , code: Cauchy. There are learning materials and live learningDDoS attacks are not as simple as we think, and are not something that Python programmers can do.To understand the hacker's use of DDoS attacks, we must know what is the most difficult reason to implement a DDoS
First, the principle of DDoS incursion
DDoS is the abbreviation of the English Distributed denial of service, that is, "scatter denial of service", the DDoS invades the principle to roughly divide into the following three kinds:
1. After sending a large packet blocking the service bandwidth to form a service line paralysis;
2. After sending a special packet to
DDoS attacks are the use of a group of controlled machines to attack a machine, so that the rapid attack is difficult to guard against, and therefore has a greater destructive. If the former network administrator against DOS can take the filter IP address method, then face the current DDoS many forged out of the address is no way. Therefore, it is more difficult to prevent

A DoS (Denial of service) attack is a deliberate attack on a network protocol implementation flaw or a brutal means of ruthlessly depleting the object's resources, so that the target computer or network is unable to provide normal service or resource access, so that the target system service system stops responding or even crashes. However, with the increase of free DDoS

I scanned it with NMAP and found that most of them are[Url = http://www.microsoft.com/china/]Microsoft[/Url]It seems that all of them are "zombie" by OWN ". Zhang Damin estimated that there are about 40 thousands or 50 Thousands different IP addresses in the attack source. The log also contains many spoofed IP Source Address packets. For a mo
According to research reports from KasperskyLabs and Imperva in the third quarter of this year, DDoS attacks have become quite frequent topics and even mask many more serious attacks, it becomes an important means of extortion and interference to enterprises or competitors.

In the face of increasingly complex network environments, various potential security problems, and no-attack attacks, our network is at any time in a dangerous place. In today's information age, ensuring stable and efficient server operations and preventing and controlling these malicious attacks have overwhelmed network administrators. In particular, DDOS, a simple and very rapid attack method, has almost overwhelmed many webmasters and network admin

Introduction to DDoS denial of service attacks
A denial of service (Denial-of-service) attack is a resource that consumes a target host or network, thereby disrupting or disabling the services it provides to legitimate users. The definition given by the "security FAQ" of the international authoritative body.
DDoS is the use of multiple computer machines, the use of distributed to single or multiple targets
As for the current network environment, vro settings are becoming more and more important. So I have studied how to completely implement DDoS Defense in vro settings. Here I will share with you, hoping to help you. What are the operations on vro settings to implement DDoS defense? First, we need to understand what the principles of DDoS attacks are before we take
Article Title: Linux anti-DDOS-Deflate. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source.
DoS-Deflate is a free service for defending against and mitigating DDoS attacks. It uses netstat to monitor and track the IP addresses that create a large number of network connectio
Use the firewall function of Linux to defend against Network AttacksVM service providers may be attacked by hackers during operation. Common attacks include SYN and DDoS attacks. By changing the IP address, it is possible to find the attacked site to avoid the attack, but the service interruption takes a long time. A thorough solution is to add a hardware firewall. However, hardware firewalls are expensive. You can consider using the firewall function
"The King of Destruction--ddos attack and prevention depth analysis"The development of cyberspace brings opportunities and threats, and DDoS is one of the most destructive attacks. This book introduces DDoS from a variety of perspectives, in order to answer some basic questions from the perspective of the attacker: who is attacking me. What is the purpose of atta
