What are DDoS Attacks?
A DDoS (Distributed Denial of Service) attack attempts to overwhelm an Internet-connected asset with the aim of making it unavailable to legitimate users. It does this by exhausting a finite resource — usually the sheer volume of traffic an asset is capable of handling — over a prolonged period, making normal use impossible. In a typical DDoS attack, the attacker sends a large number of requests to the targeted asset, aiming to exceed the asset’s capacity to handle that type of request. Since the asset is now ‘exhausted’ in that area, legitimate users cannot interact with it properly.

How does DDoS work?
Classic flooding attacks that aim to exceed the maximum bandwidth of a targeted asset. These attacks take advantage of Internet protocols like UCP and ICMP, which don’t require the receiving asset to ‘accept’ each packet of data. Most modern volumetric attacks use botnets (armies of Internet-connected devices enslaved by malware) to overwhelm targets with a massive volume of data packets.
Also called ‘traffic attacks’, protocol attacks consume server resources rather than pure bandwidth. Unlike volumetric attacks, which rely on data volume, protocol attacks force target servers (and other equipment like firewalls) to respond to more data packets than they can handle. The targeted asset becomes overwhelmed and can no longer serve legitimate users.
Unlike volumetric and protocol attacks, which overwhelm the infrastructure responsible for serving a web asset, application attacks target the asset itself. Using a flood of application-layer requests (e.g., HTTP GET/POST requests) these attacks exhaust the capabilities of a targeted website or application.
Your advantages of the patented Link11 anti DDoS solution
Self-Learning AI Shield
One Step Ahead
All attacks that Link11 fends off are stored in a sequence database. The self-learning AI of the anti DDoS solution analyses each attack sequence and compares it in real time with threat patterns. All protected companies benefit from this, as similar incidents are anticipated, and an ever-faster response is achieved.
Always on – guaranteed
Real-time mitigation for a DDoS attack takes effect within 0 to 10 seconds – for each attack vector. If you choose the Always-On variant via BGP, Link11 offers 24/7 support and automatically detects and mitigates attacks. Human error can thus be excluded. With guaranteed protection bandwidths. Without any cost traps in case of long-lasting attacks.
Protection on all layers
Thanks to the intelligent architecture, all types of DDoS attacks are comprehensively fended off. Depending on connection and booked service with Web DDoS and/or infrastructure DDoS protection, Link11 offers reliable defense against DDoS attacks on layers 3 to 7 and is ready for use within minutes.
