The type of attack designed to overwhelm a server with traffic is known as a DDoS (Distributed Denial of Service) attack. In this attack, multiple compromised systems, often part of a botnet, flood a target server with excessive traffic, leading to service disruption and rendering the website or application inaccessible to legitimate users. DDoS attacks can target various services and are often used to extort organizations or as a form of protest. To mitigate these attacks, organizations implement traffic monitoring and filtering solutions to identify and block malicious traffic patterns.
