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

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

Installing wireshark in centos is quite simple. Two commands are enough. Here, we mainly record the installation of writing usage: 1. yuminstallwireshark. Note that wireshark commands and graphical interfaces cannot be used. However, it provides basic packet capture functions. 2. yuminstallwireshark-gnome. This makes it easy to use. If you can log on to the graphic interface terminal, there is no difference

DDoS attack conceptThere are many types of Dos attacks, the most basic Dos attack is to use reasonable service requests to consume excessive service resources, so that legitimate users can not get the response of the service.DDoS attack is a kind of attack method based on traditional Dos attack. A single Dos attack is usually one-to-many, when the target CPU speed is low, the memory is small or the network bandwidth is small, and so on the performance
