DDoS deflate is actually a shell script that uses Netstat and iptables tools to block IP that has too many links, effectively preventing common malicious scanners, but it is not really an effective DDoS defense tool.
Work Process Description:
The same IP link to the number of connections to the server after the setting of the cut value, all over the cut value of the IP will be masked, while the shielding

Xoic is another good Dos attack tool. It performs Dos attacks on any server based on the port and protocol that the user chooses. Xoic developers also claim that Xoic is more powerful than Loic in many ways.
Generally speaking, the tool has three kinds of attack mode, the first is called Test mode, is very basic; The second is the normal Dos attack

I think now everyone contact with the VPS for a long time, also know that the Internet is ddos,cc is the norm, in the absence of hard defense, looking for software replacement is the most direct method, such as with iptables, but iptables can not be automatically shielded, can only be manually shielded, Today, I would like to introduce you to a software that can automatically block Ddos,cc,syn attacks:
April 19, 2010 Morning |VPS DetectiveObjectiveThe internet is as full of rivalry as the real world, and the site has become the most headache for webmasters.

What we're going to talk about today is a software that automatically shields DDoS attackers ' IPs:
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
The basis for successfully mitigating DDoS attacks includes: knowing what to monitor, monitoring these signs around the clock, identifying and mitigating DDoS attacks with technology and capabilities, and allowing legal communication to reach the destination, real-time skills and experience in solving problems. The best practices discussed below reflect these principles.

DDoS attack wave affects Enterprise Development
DDoS attacks cannot be ignored by enterprises nowadays. In particular, for some large enterprises, their main businesses are accumulated in servers. If the servers are attacked, the loss of important information or con
DDoS attacks are essentially time-series data, and the data characteristics of t+1 moments are strongly correlated with T-moments, so it is necessary to use HMM or CRF for detection! --and a sentence of the word segmentation algorithm CRF no difference!Note: Traditional DDoS detection is directly based on the IP data sent traffic to identify, through the hardware firewall. Big data scenarios are done for sl
Ddos-deflate Installation and Configuration
1, installation
The code is as follows
Copy Code
wget http://www.inetbase.com/scripts/ddos/install.shChmod 0700 install.sh./install.sh
2, configuration
The configuration file is/usr/local/ddos/ddos.conf and is configured as follows by default
The code is as follows
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

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
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
Ddos-deflate is a very small tool for defense and mitigation of DDoS attacks, which can be tracked by monitoring netstat to create IP address information for a large number of Internet connections, by blocking or blocking these very IP addresses via APF or iptables.We can use the Netstat command to view the status of the current system connection and whether it is compromised by a
