DDoS (distributed denial of service) attacks have been a serious and persistent threat to the availability of networks, websites, and other internet-facing services for more than 25 years. And they are growing in intensity.
The steady and ongoing annual increase in the frequency, duration, and size of DDoS attacks is the product of multiple factors: rising broadband speeds available to home and mobile users; the ability for attackers to leverage amplification attacks to increase the effective available bandwidth; increasing numbers of vulnerable servers and web applications that can be combined into a botnet; and the proliferation of internet-connected devices.
