Ddos

DDoS is a type of cyberattack where multiple compromised computers, known as a botnet, flood a target system, network, or website with a massive amount of traffic or requests. The overwhelming volume of traffic disrupts the target's normal operation, leading to service degradation or complete unavailability, denying legitimate users access to the targeted resource.
