A distributed denial of service (DDoS) attack overwhelms a server, service, or network with internet traffic to disrupt or halt normal operations. This is typically achieved by multiple compromised systems flooding the target with traffic. The result is that legitimate users cannot access the systems or services, causing significant operational and financial impact.
