This makes DDoS attacks harder to block and more disruptive than a standard denial-of-service (DoS) attack.<\/p>\n<p>A <strong>DoS (denial-of-service) attack<\/strong> works similarly but uses a single source to flood a target with traffic or exploit vulnerabilities.

A DoS attack is launched from one source, while a DDoS attack comes from many, making it more difficult to mitigate and more damaging to the target.
