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;

Mod_evasive is a DDoS-resistant module for Apache (httpd) servers. For Web servers, it is now a good extension to protect against DDoS attacks. Although it is not completely defensive against DDoS attacks, under certain conditions, it is still the pressure to slow down the Apache (httpd) server. If you work with iptables, hardware firewalls, and other firewall de
Then, how can we determine whether the website is under DDOS attacks? In summary, when the website is under DDOS attacks, the following symptoms may occur: If the website server has all of the following symptoms, the website is basically determined to be under DDOS attacks.
1. The normal services provided by the website become abnormal.
This symptom is: The Webpa
When it comes to the ultimate weapon of hackers, it really has to be about DDoS. Can some users of this thing is not very know, but the people engaged in computer security is often heard this name, its degree than the fear of the grave. After all, this DDoS has some place to be so fearful, below will make some brief elucidation to you.
In general, the DOS approach is your network's TCP/IP interior layout,
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
Free DDoS attack test Tool Dahe Set
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

Popen (command, Shell=true)If command is not an executable file, Shell=true cannot be saved.Using the Subprocess module, you can create new processes that can connect to the input/output/error pipelines of the new process and get the return status of the new process execution. The purpose of using the Subprocess module is to replace old functions or m

The new project is about to be launched. This is the first project that you are responsible for, from development to implementation.
As soon as I got online, my mind would naturally imagine how I went to the client to get him xxxxxxx and so on. The process was first passed in my mind. In fact, I was familiar
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.
