The DNS Protection is a cost-efficient solution especially designed to protect a company‘s web applications. The solution requires no extra server infrastructure, additional bandwidth or new router technology. All traffic will be routed to the Link11 filter center. Therefor, the DNS A record entries of the affected application are adapted.
In the first stage, all unwanted traffic types are filtered out by the DDoS filter cluster, based on customer specifications. Signature-based detection uses more than 100 validation features to protect against known Layer 2 and Layer 3 attacks. Customized configurability ensures a low rate of false positives.
After analyzing, the DDoS requests are blocked or sent to a customized Captcha site and only legitimate users are forwarded to the server. This protects the server against all DDoS attacks while giving all legitimate users access as normal.
The BGP protection provides comprehensive protection of the entire enterprise network. This solution requires a /24 (class C) or larger IP network for rerouting.
Link11’s DDoS protection via BGP can be used in a hot-standby variant and maintain the normal data flow as long as there is no attack. In the event of an attack, the data transfer is routed over the Link11 filter center. With the standby integration, both the customer and the Link11 security team can initiate in the case of an attack immediate protection by the announcement of the network. The filtered data packets are transmitted to the filter center through an encrypted tunnel (VPN, IPsec, GRE). After the DDoS attack is successfully repelled, the data transfer is rerouted back to its original route.
If the Link11 monitoring is added, the flow data of the local routers will be analyzed to determine when the Link11 protection should be automatically activated in the event of an attack
