best ddos program

the server may have to trace a record from tens of thousands of records to handle the request, a process that is expensive for resources, Common database servers rarely support hundreds of of simultaneous query execution, which is easy for the client, so the attacker can simply submit a query to the host server via proxy proxies, consuming server resources in minutes and causing a denial of service. Common phenomenon is that the site is slow, such as snail, ASP

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

1. Common DDos attack types SYN Flood: it is currently the most popular DoS (DoS attacks) and is a type of TCP connection request that uses TCP protocol defects to send a large number of forged TCP connection requests, so that the attacked party's resources are exhausted (the CPU is full or the memory is insufficient. Smurf: This attack sends a packet with a specific request (such as an ICMP Response Request) to a subnet broadcast address, and disguis

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

The internet is rich and colorful, basically able to find the resources we need, but also because so many friends are joined to the ranks of the webmaster. Among the many stationmaster also can exist infighting thing. In particular, our personal webmaster, due to limited technical and financial resources, very easy to use on the host, VPS after the attack did not have the ability to defend, leading to our host or VPS to our account suspension, IP hangs and so on. In particular, we are using the

1, Baidu search 360php-ddos script Kill tool we enter to 360 official to download this toolkit. 2, download the Good toolkit after we upload the 360doskill.php to your site root directory. 3, then we directly in the browser to access 360doskill.php, access to address: http://site domain name/360doskill.php 4, then we enter the default username and password login. 5, then we click on the scan can scan the entire directory, of course, you can al

DDoS deflate, ddosdeflate 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

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

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 free script for defending against

phenomena are website slowness, such as snail ing, ASP program failure, PHP database connection failure, and high CPU usage of the database master program. This attack is characterized by completely bypassing common firewall protection and easily finding some Proxy agents to launch attacks. The disadvantage is that the effect of websites with only static pages is compromised, in addition, some proxies expo

programs, and call MSSQLServer, MySQLServer, Oracle and other databases of the Web site system design, characterized by the server to establish a normal TCP connection , and constantly to the script to submit queries, lists, and so a large number of resource-consuming database resources, typical of a small broad attack method. In general, the cost of submitting a GET or post instruction to the client is almost negligible, and the server may have to trace a record from tens of thousands of reco

hard to find. The intruder controls some nodes and designs them into control points, controlling a large number of hosts on the internet, designing them as attack points, and loading the attacking program in the attack point, which is the attack that the computer attacks on the target. The prelude to DDoS attacks is the first to compromise some of the less secure computers as control point hosts. Because t

a DDoS master program on a computer, in which a set time master will communicate with a large number of agents, and the agent is already installed on many computers on the Internet. An agent launches an attack when it receives an instruction. With client/server technology, the master program can activate hundreds of agents within seconds.Iii. the phenomenon of b

I. Distributed blocking services (distributed denial of service) DDoS is a special case of DoS, hackers use multiple machines to attack at the same time to prevent normal users to use the service. After hackers have invaded a large number of hosts beforehand, to install DDoS attack on the victim host to attack the target; some DDoS tools use a multi-level archit
