Arbor Networks has launched the latest version of its Peakflow threat management system (TMS) with 40GB capacity added.

The company claimed that version 5.1 identifies and surgically removes network and application-layer attacks without interrupting the flow of legitimate traffic. It also includes new capabilities to secure DNS servers and infrastructures that are under a significant number of targeted application-layer attacks, and offers IPv6 visibility and security.

Rakesh Shah, project manager for Arbor Networks, explained that Peakflow operates with two essential components – Peakflow SP that collects and analyses IP flow, BGP and SNMP data and the TMS that is used for surgical mitigation of attack traffic and conducts service performance monitoring.

The SP will detect malicious traffic and send it to the TMS which also serves as a platform for in-cloud managed security services.

Shah said: “Most denial-of-service (DDoS) attacks can lead to collateral damage but because other customers or servers are on a shared platform you may have a shared service. The DDoS is the number one threat to data centres and the cloud, it can impact other organisations and even some infrastructure, and it can interrupt ‘always on' services.”

Shah explained that the next version moves it from 10GB to 40GB and is the first product to do DDoS mitigation as it deals with large attacks and does application layer attack mitigation.

For customers, version 5.1 allows capacity to be shared across different customer platforms, while Shah said that customers who already have the 10GB solution can remove the blade and put in the 40GB blade as this is viewed as an ‘investment product'.

Shah said: “We looked at IPv6 security insight and saw that global traffic grew by more than 1,400 per cent at a spectacular rate. We had requests to have visibility into traffic so we put in full visibility and security.”

Finally Shah said that DNS protection had also been added, and that in many cases if the DNS infrastructure goes down it means that all servers are down, so Arbor added a number of tools for DNS attacks.

Rob Malan, Arbor Networks co-founder and chief technology officer, said: “There are a couple of industry firsts in this release, including 40GB mitigation of distributed DDoS and application-layer attack traffic, as well as visibility and security into IPv6 traffic, which will become increasingly important to our service provider customers as they transition to IPv6 in the months and years ahead.”
