RSA Conference 2003

--(BUSINESS WIRE)

Where:    Moscone Center
          San Francisco, CA

When:     11:15 AM, Wednesday April 16, 2003
          11:00 AM, Thursday April 17, 2003

What:     Martin Roesch, founder and CTO of Sourcefire, Inc., a leader
          in protecting enterprises and government organizations
          against the threat of network attacks and misuse, is
          presenting his insights on intrusion detection and corporate
          network security during several "class tracks" at next
          week's RSA Conference in San Francisco. Roesch will also
          provide insights and real world examples on detecting
          threats and protecting corporate networks against attacks,
          based on his experiences at Sourcefire and as creator of the
          Snort(TM) Intrusion Detection System.

          In the first session, "Using IDS Tagging to Nab Attackers"
          at 11:15 AM on Wednesday, April 16, Roesch will discuss how
          companies can use their Intrusion Detection System to track
          attackers by logging traffic after an initial exploit is
          detected. He will detail how the IDS can record all activity
          on a particular host or session for a definable number of
          seconds or packets, increasing the chances of stopping the
          attacker.

          During the second session, "IDS Challenges, Emerging
          Technology & Deployment Trends" at 11:00 AM on Thursday,
          April 17, Roesch will take part in a panel discussion that
          will address the shortfalls of Gigabit IDS, emerging
          alternative IDS strategies with active defense, and overall
          trends in the IDS implementation arena.

Who:      Martin Roesch is a respected authority on intrusion
          detection technology and forensics and is responsible for
          the technical direction and product development efforts at
          Sourcefire. He has 14 years of industry experience in
          network security and embedded systems engineering. Mr.
          Roesch is also the author and lead developer of the award
