Anti-DDoS, or Anti-Distributed Denial of Service, refers to a set of security measures and protocols designed to mitigate and counteract the effects of distributed denial-of-service (DDoS) attacks. These attacks involve multiple compromised computer systems targeting a single system, causing a disruption in its normal traffic and preventing legitimate users from accessing the service.

Anti-DDoS solutions typically involve various techniques and technologies aimed at identifying and blocking malicious traffic before it can overwhelm the targeted system. These measures often include advanced threat detection systems, real-time monitoring, and traffic analysis to distinguish between legitimate and malicious traffic. Additionally, Anti-DDoS strategies may utilize measures such as rate limiting, black-holing, or rerouting traffic to specialized scrubbing centers to filter out malicious data and ensure the continuity of regular operations.
