Distributed Denial of Service attack, or shortly DDoS attack, is a cyber threat that aims to make an online service unavailable to users. Usually, it disrupts the performance of a website, server, or network. DDoS attacks are initiated with many compromised devices, known as a botnet. They flood the victim with malicious traffic. As a result, the target gets sluggish and eventually becomes unable to function. Learn more about DDoS attacks!
