TestomatoBot and DDoS protection

What is DDoS (Denial-of-service attack)​

Denial-of-service attack (DoS attack) is a cyber-attack in which the perpetrator seeks to make a machine or network resource unavailable to its intended users by temporarily or indefinitely disrupting services of a host connected to the Internet. Denial of service is typically accomplished by flooding the targeted machine or resource with superfluous requests in an attempt to overload systems and prevent some or all legitimate requests from being fulfilled. DDoS attacks achieve effectiveness by utilizing multiple compromised computer systems as sources of attack traffic.
