A Denial-of-Service (DoS) attack aims to make an application or website inaccessible by overwhelming it with excessive data, causing its network to overload.
A DoS attack originates from a single source.
Distributed Denial-of-Service (DDoS) attacks originate from multiple sources, unlike DoS attacks.
Similar to DoS, DDoS aims to make an application or website inaccessible.
The attack may involve multiple attackers or a single attacker using bots—infected computers that automatically overwhelm the target with excessive traffic.
