Overview

Colt IP Guardian is intended to help Colt customers reduce the impact of Denial of Service (DoS) and Distributed Denial of Service (DDoS) attacks.

When you experiences a DDoS attack, not only does the attack itself jeopardise IT infrastructure, but ISPs are often forced to discard all traffic to the affected address range in order to prevent network degradation from impacting others on the network.

Subscribing to the IP Guardian service removes this risk by ensuring that effective DDoS protection is in place, removing any threat or blackholing.

  • Ensure rapid detection of any abnormal activity

  • Near continuous uptime and the best possible round trip time (RTT)

  • Protect your assets as the mitigation happens upstream

  • Continue using its Internet service whilst under attack

How it works

In order to deliver the Colt IP Guardian service, Colt has implemented a state-of-the-art platform based on Arbor Threat Management System (TMS) and Arbor Peakflow monitors. These have been installed at strategic locations within Colt’s Tier 1 network (Frankfurt, London, Madrid, Milan, Paris and New York) and are available to protect your connectivity to the Internet.

The traffic to your network is constantly monitored while it follows its path in the network. The Arbor Peakflow SP Collectors gather traffic statistics (network telemetry data) from all peering and transit routers which it constantly analyses to construct a network-wide view of possible traffic and network anomalies. An alert is generated if the behaviour is found to be abnormal.

When an attack is detected by Arbor Peakflow SP, traffic is automatically diverted to Arbor TMS, which mitigates the attack based on traffic patterns learned by Arbor Peakflow SP. This means that only the cleaned traffic flows toward the customer, which will be provided with high levels of protection.

It is the tight integration between the Colt network and the Arbor platform that ensures customer traffic only needs to be rerouted when an actual attack is detected. When redirection does occur, the TMS devices traffic is redirected to are located as close to the upstream peering and transit connections as possible, which drastically reduces the additional latency overhead.
