Before we look at this issue, let's talk about what DDoS is: What is DDoS: 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 t

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

Anti-DDoS SolutionDDoS attack defense scheme has a large number of recent DDoS attack events (Analysis of DDoS attack events in 2014). We are all thinking about how to defend against DDoS attacks in the face of ddos attacks? In the green alliance Technology Security + Techno

, please follow the AB tool or test script out of the results to view; Note: Because when we compile mod_evasive, we use the default configuration, so the logs are stored in the/tmp directory. If there is a DDoS attack, the log will be generated in/tmp. The log file begins with the dos-; vi. Detailed configuration Parameters Doshashtablesize 3097: Defines the hash table size.
