Surveillance Detection in High Bandwidth Environments

Tags:
bandwidth issues

Overview This paper describes System Detection's surveillance detection techniques for enclave environments (ESD) and peering center environments (PSD) and evaluates each technique over data gathered from two different network environments. ESD is evaluated over 74 hours of tcpdump packet traces (344 million packets) from a large enclave; PSD is evaluated over 5 hours of tcpdump packet traces (110 million packets) gathered from a peering center. Both surveillance detection modules were executed over the audit data offline to generate surveillance detection alerts, though the systems can be run in real-time as well. The results show that both ESD and PSD accurately discover great quantities of surveillance activities (including long-lived and distributed scans) and can be tuned to reduce the volume of alerts.

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?

Telecom 2.0: Mind over matter

ntl:Telewest Business believes that the role of the telco is evolving. Gone are the days when it was enough to simply focus on circuits and minutes, customers now need a far higher degree of interaction and look for suppliers who will talk business solutions with them.
