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

the site as far as possible to make static pages, not only can greatly improve the anti-attack ability, but also bring a lot of trouble to hackers, at least until now, the overflow of HTML has not appeared, see it! Sina, Sohu, NetEase and other portals are mainly static pages, if you do not need dynamic script calls, it will get to another separate host to go, free from the

proposes a method of DDoS attack detection on the basis of HMM and source IP address monitoring. The method uses the source IP address information in the network data stream to express the characteristic of the network traffic state. First, the common source IP address library is studied according to the normal data flow, and then the statistical modeling of the dynamic IP address sequence of the network d

Preface As in the real world, the Internet is full of intrigue. Website DDoS attacks have become the biggest headache for webmasters. In the absence of hardware protection, finding a software alternative is the most direct method. For example, iptables is used, but iptables cannot be automatically blocked and can only be manually shielded. Today we are talking about a software that can automatically block the IP address of

shows that 80% of your website accesses by proxy are malicious.6. Enhance the TCP/IP stack of the Operating SystemAs a server operating system, Win2000 and win2003 have the ability to defend against DDoS attacks, but they are not enabled by default. If they are enabled, they can defend against about 10000 SYN attack packets, if it is not enabled, it can only defend against hundreds of attacks. For details

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

software to simulate a lot of this, the consequences can be imagined. A server consumes a lot of system resources and network bandwidth to handle these vast amounts of half-open information, so that the server will no longer be free to handle normal user requests (because the customer's normal request ratio is very small). This server will not work, this attack is called: Syn-flood

time is about 30 seconds-2 minutes. If a user encounters a connection problem and a thread on the server waits for one minute, it is not a big deal. However, if someone uses special software to simulate this situation, the consequences can be imagined. If a server processes a large amount of semi-connection information and consumes a lot of system resources and network bandwidth, in this way, the server will not be free to process normal requests of

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 deflate is a
