The acronym "DDoS" stands for Distributed Denial of Service in the context of cybersecurity. A DDoS attack involves overwhelming a targeted server, service, or network with a flood of traffic from multiple sources, rendering it inaccessible to legitimate users. Attackers typically exploit compromised devices, known as a botnet, to carry out these attacks, making it challenging to distinguish between harmful and legitimate traffic. DDoS attacks have significant implications for organizations, often resulting in financial losses and damage to reputations.
