cold, we can treat, but also can be prevented, but not cure, but if we take a positive and effective defense methods, can greatly reduce or slow down the chance of illness, to combat DDoS attacks, It is necessary to have sufficient bandwidth and high-level host hardware, so what is sufficient bandwidth? In general, it should be at least 100M shared, so what is the host hardware that is high enough to configure? In general, it should be at least P4 2.

find low-level DDoS is not working, they will increase the attack strength. At the beginning of our official website, the average number of concurrent only thousands of, then increased to an average of 16,000 concurrent, up to 70,000 concurrent, so that the CPU monitoring on top of the effect, because the w3wp.exe restart, in a very short period of time the CPU to reach 100%. Number of concurrent connecti

DDos (Distributed denial of service), distributed denial of service, often found such attacks in games, online business, and so on, are generally competitors. What are the ways of DDoS attacks?1 Traffic attack (four layers)Mainly for network bandwidth attack, that is, a large number of

DDoS attack tracking Distributed denial of service (DDoS) attacks are a serious threat on the internet. However, the memory-free functionality of the Internet routing mechanism makes it difficult to trace the source of these attacks. Therefore, there is no effective way to deal with this problem so far. The common way

Therefore, the method of attacking the city is the last resort. Know yourself, know yourself, do not know, do not fight -- Sun Tzu's Art of War We will implement a tool for DDoS attacks at the application layer. in comprehensive consideration, the CC attack method is the best choice. We will use the bash shell script to quickly implement and verify this tool. At the end, discusses how to defend against

be prevented, but not radical cure, but if we adopt a positive and effective defense methods, can greatly reduce or slow down the chance of illness, the prevention of DDoS attacks is also the case, It is necessary to have sufficient bandwidth and high enough host hardware to be configured, so what is sufficient bandwidth? In general, should be at least 100M sharing, then what is the configuration of high enough host hardware? In general, it should be

Today in order to rest, change the brain, so I found a previous collection of Python article, is about DDoS attack a script, just today is free, on the practice.

related to online games. Some players are dissatisfied with being killed or losing their favorite weapon in the game, thus initiating a denial of service attack, many of which are now the victims of such attacks. But now the intent to use denial is mostly simple extortion. More and more companies are beginning to rely on their IT infrastructure. Mail, key data, and even the telephone network to dispose of. Without these primary channels of communica

Anti-DDoS: CC attack defense system deployment1. System effect this DDOS Application Layer defense system has been deployed on the http://www.yfdc.org site (if access fails, please directly access the server in China http: // 121.42.45.55 for online testing ). The defense system is at the application layer, which effectively prevents the abuse of server resources

Common web attacks fall into two categories: one is to exploit the vulnerabilities of Web servers, such as CGI buffer overflow, directory traversal exploits and so on, and the other is to exploit the security vulnerabilities of Web pages, such as SQL injection, cross-site scripting attacks, etc. The following article mainly introduces the PHP security protection of the Web attack, the need for friends can r
