Distributed Denial-of-Service (DDoS) Attacks

Distributed denial-of-service (DDoS) attacks attempt to render a website or network resource unavailable by overwhelming it with a flood of traffic from multiple sources. These malicious attacks rely on computers and similar devices (such as IoT devices) that are infected with malware. The threat actor will instruct this network of infected devices to target the victim’s IP address, resulting in a “denial of service” to normal site visitors, as the server or network has become overwhelmed.

Large-scale DDoS attacks can bring down servers and networks, interrupting business operations and causing significant economic damage. To defend against DDoS attacks, organizations will often overprovision bandwidth and implement anti-DDoS hardware. Cloud-based DDoS mitigation services offer continuous monitoring and real-time response, helping ensure services remain available to legitimate users.
