The acronym "DDoS" stands for Distributed Denial of Service, which refers to a type of cyber attack aimed at overwhelming a target's resources, such as a server, network, or service. By flooding the target with a massive volume of traffic from multiple compromised systems, attackers render the service unavailable to legitimate users. DDoS attacks can disrupt business operations significantly and may serve various malicious intentions, including financial extortion or competition sabotage. As a result, robust security measures are vital to mitigate the risk of such attacks.
