    Presentation Overview

    Snort, Sourcefire, and Intrusion Detection Systems

    Our first presentation will be from Sourcefire, which was founded in 2001 by the original creators of the open-source Snort Intrusion Detection System (IDS), the industry's most widely deployed IDS, that forms the foundation for the Sourcefire product suite. Today, Sourcefire combines the Snort technology with sophisticated proprietary technologies, professional data analysis and management tools, along with best practices from respected security industry experts. Sourcefire is a privately held company headquartered in Columbia, MD.

    Martin Roesch is the author of Snort, and will discuss:

    • The genesis of Snort
    • Future directions in Intrusion Detection Systems (IDS)
    • Integrating open source and proprietary technologies into a product line

    Voice Authentication - Biometric Security With Just a Microphone

    Our second presentation covers voice authentication, which offers an exciting way to add a layer of biometric security to business applications without installing any additional hardware, by taking advantage of a standard computer microphone or the POTS (Plain Old Telephone System).

    Nuance is a leading supplier of speech recognition, voice authentication and text-to-speech software. Nuance was spun out of SRI in 1994, and its customers include British Airways, Nomura Securities, OnStar, Sprint PCS, United Parcel Service, and Vodafone.

    Laura Marino is an expert in speaker verification, and will discuss:

    • What are the best applications for speaker verification?
    • How much can voice authentication save by reducing fraud?
    • How secure is voice versus other biometric authentication technologies?
    • What are speaker verification technology limitations?
    • What are the latest technical advances?
    • What's the easiest way to integrate speaker verification into an existing web site?
