Home Resource Center Glossary DDoS

DDoS is an acronym for Distributed Denial-of-Service. It’s a type of attack where hundreds or even thousands of client computers are hijacked by a hacker to strike against a single system, network or application. If an organization becomes compromised by a DDoS attack, whatever service it provides becomes unavailable to its employees and customers.

DDoS attacks are often perpetrated by an army of virus-laden, remotely controlled computers. Since there are so many inbound server requests coming from so many distributed computers, it’s difficult to distinguish these attacks from legitimate traffic. The goal of a DDoS attack is either to cause costly downtime or to extract some form of ransom from the victim organization.

To protect against DDoS attacks, organizations need to prevent advanced application layer attacks, such as HTTP floods or Slowloris, and large-scale volumetric attacks. This requires high-performance solutions that can intelligently inspect, stop, and redirect application traffic at networks speeds.

DDoS attacks are increasing in both frequency and scale and have left some of the world’s largest data center and network operators dealing with their costly aftermath. Virtually every commercial and government organization is reliant on the availability of their online services, and service availability is at risk from the rising tide of DDoS attacks. All organizations should be concerned about major service outages due to DDoS attacks and take measures to ensure that their DDoS mitigation solution can scale to handle the largest multi-vector attacks at their network edge.
