Anti-DDoS

Fending off distributed denial-of-service attacks

Many publicly available company websites are subjected to criminal attacks. One common scenario is the overloading of a website by flooding it with a large number of requests from different IP addresses within a short period of time, also known as a distributed denial-of-service (DDoS) attack. The sheer number of requests brings the website to its knees and the service becomes unavailable. This is a highly unpleasant scenario for the operator of a service. Website operators can protect themselves against DDoS attacks with a software-based security function: Anti-DDoS automatically detects DDoS attacks by checking incoming requests. In the event of an attack, it diverts the unwanted requests and ensures that the service remains available without any additional resources being required.

Anti-DDoS in the Open Telekom Cloud

Anti-DDoS is a free, additional component that complements the range of hardware security functions in Telekom data centers. The Open Telekom Cloud’s platform-wide and extensive runtime monitoring ensures that DDos attacks are automatically detected. The Anti-DDoS service enables users to define defense parameters and assign unused ports for redirecting the unwanted requests. Alternatively, it is also possible to use solutions from third-party providers that immediately dispose of undesired network traffic. The Open Telekom Cloud provides reports with detailed information on the attacks to allow users to gain a clear and comprehensive overview at any time.

The Anti-DDoS service has an “IP reputation service” that supports millions of IP addresses and monitors both incoming and outgoing traffic. Using these mechanisms, requests from botnets can be detected and filtered quickly and easily. The Anti-DDoS service ensures that only unwanted traffic is filtered out, for both UDP and TCP cleaning.
