Okay, enable the following:1. To defend against DDOS attacks, you m

Linux defense Small Scale DDoS attack configuration method

Defense principleThe principle of DDoS deflate is to use the netstat command to find a single IP that emits an excessive amount of connectivity and to reject the IP using the iptables firewall. Because the iptables firewall is far more efficient than the Apache-level connection, the iptables becomes the "filter" that runs on the Apache front end. Similarly, DDoS deflate can also be set up to use APF (advanc

How to deploy defense measures against DDos attacks

Author: Ion wing. sun Source: SCID DDoS (Distributed Denial-of-Service) attacks are mainly used to flood the pipeline by means of traffic that exceeds the pipeline's processing capability or by means of tasks that exceed the processing capability to paralyze the system, therefore, in theory, as long as attackers can gain more powerful "power" than the target, the target will be attacked. There are no 100% effective defense measures for

of the system. For example, we must clearly know which services are open to the system and which access is forbidden. At the same time, when there are signs of a DDoS attack, we should also determine which processing mechanisms the attack uses. Although we have heard of countless people repeatedly "shutting down unnecessary services", it is clear that its importance is not fully recognized. Sometimes, when a port is not opened, we think it is in a sa

The principle and prevention of distributed denial of service attack (DDoS)

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
