Understanding Victims: Six Principles for Systems Security: The success of many attacks on computer systems can be traced back to the security engineers not understanding the psychology of the system users they meant to protect. It examined a variety of scams and "Short Cons" that were investigated, documented and recreated for the BBC TV programme The Real...; Tags: University Of Cambridge, Security; White papers 2009-06-11
Stopping Spam by Extrusion Detection: End users are often unaware that their systems have been compromised and are being used to send bulk unsolicited email spam. This paper shows how automated processing of the email logs recorded on the "Smarthost" provided by an ISP for their customer's outgoing email can be used to detect this...; Tags: University Of Cambridge, Detection, E-mail, Online Communications; White papers 2009-01-01
Traffic Analysis of the HTTP Protocol Over TLS: The paper analyzes attacks that take advantage of the data length information leaked by HTTP transactions over the TLS protocol, in order to link clients with particular resources they might access on a web site.

Security Economics and European Policy: As Europe moves online, information security is becoming increasingly important: first, because the direct and indirect losses are now economically significant; and second, because growing public concerns about information security hinder the development of both markets and public services. While information security touches on many subjects from mathematics through law...; Tags: Information Security, University Of Cambridge, Security; White papers 2008-06-23
Cooperative Attack and Defense in Distributed Networks: Computer networks are becoming increasingly decentralized. No single entity controls the entire system; therefore, no entity can compel compliance. Peer-to-peer file sharing systems connect users to exchange information, yet lack a hierarchical organization so they can increase efficiency and avoid single points of failure. Wireless sensor networks are assembled from...; Tags: University Of Cambridge, Network, Distributed Network, Attack, Networking; White papers 2008-06-01
Leading University Creates UK's Fastest Academic Supercomputer Through Collaborative Partnership: Cambridge University has had supercomputers for use in complex research since 1992. Undertaking ground breaking research, users require cutting edge technology that provides optimum performance. At the end of a three-year system cycle, the university looked to implement a new system that would improve upon previous levels of high performance....; Tags: Dell Computer Corp., University Of Cambridge, Partnership, Supercomputer, High-performance, Leadership, Management; Case studies 2008-04-30
Honeycomb - Creating Intrusion Detection Signatures Using Honeypots: This paper describes a system for automated generation of attack signatures for network intrusion detection systems. The system applies pattern-matching techniques and protocol conformance checks on multiple levels in the protocol hierarchy to network traffic captured a honeypot system. This paper presents results of running the system on an unprotected...; Tags: Cable Modem, University Of Cambridge, Signature, Cable, Intrusion Detection, Modems, Broadband Internet, Network Technology, Security, Telecommunications, Personal Technology, Hardware, Components, Networking; White papers 2008-01-01
Policy-Controlled Event Management for Distributed Intrusion Detection: A powerful strategy in intrusion detection is the separation of surveillance mechanisms from a site's policy for processing observed events. The Bro intrusion detection system has been using the notion of policy-neutral events as the basic building blocks for the formulation of a site's security policy since its conception. A...; Tags: University Of Cambridge, Event, Bro Intrusion Detection System, Intrusion Detection, Network Security, Security, Networking; White papers 2008-01-01
Augmented Statistical Models for Speech Recognition: Recently there has been significant interest in developing new acoustic models for speech recognition. One such model, that allows complex dependencies to be represented, is the augmented statistical model. This incorporates additional dependencies by constructing a local exponential expansion of a standard HMM. Unfortunately, the resulting model often has an...; Tags: University Of Cambridge, Model, Speech Recognition, Emerging Technologies; White papers 2008-01-01
Architecture of a Network Monitor: This paper describes a system for simultaneously monitoring multiple protocols. It performs full line-rate capture and implements on-line analysis and compression to record interesting data without loss of information. The researchers accept that the balance must be maintained in such a system between disk-bandwidth, CPU-capacity and data-reduction in order to...; Tags: Monitor, University Of Cambridge, Researcher, Network, Monitoring; White papers 2007-12-01
Email Traffic: A Quantitative Snapshot: With unsolicited email costing businesses millions in wasted employee resources and productivity, and acting as the carrier for a host of potential security woes, spam and blended email threats are among the biggest problems facing enterprises today.
