What is DDoS Attack in cyber security?

An attack that overwhelms a network or website with excessive traffic, causing it to crash.

A Distributed Denial of Service (DDoS) attack occurs when multiple systems flood a targeted network or website with excessive traffic, overwhelming its capacity and causing it to crash or become inaccessible. Attackers often use botnets—a network of infected computers—to carry out these attacks. The goal is to disrupt services, harm the target's reputation, or extort money. To defend against DDoS attacks, organizations can use specialized security solutions that detect and mitigate excessive traffic in real time.
