ADVISORY...for Saturday, Aug. 31

--(BUSINESS WIRE)

Computerworld Security Reporter to Discuss Threat to the

Private Sector, Defense Strategies on "All Things Considered"

WHO:   Dan Verton,  senior writer for IDG's Computerworld,
       a weekly news magazine for IT leaders, and author of
       "The Hacker Diaries."

WHAT:  In a nationally broadcast segment of National Public
       Radio's (NPR) "All Things Considered" program,
       Verton will provide commentary on the threat
       cyberterrorism poses to the nation, with particular
       focus on risks facing the private sector. In
       addition to distinguishing between cyberterrorism
       and cyber-graffiti, Verton will outline what, if
       anything, can be done to defend against the danger
       of computer-based terrorism.

WHEN:  Saturday, August 31, 2002

WHERE: Tune in to:

       WBUR-FM 90.9 in Boston at 5 p.m. EDT

       WAMU-FM 88.5 in Washington, D.C. at 6 p.m. EDT

       WBEZ-FM 91.5 in Chicago at 4 p.m. CDT

       WQED-FM 88.5 in San Francisco at 5 p.m. PDT

WHY:   According to Verton, cyberterrorism is "the
       targeting of our nation's infrastructure at its
       weakest point - the computer networks that control
       and manage critical services, such as electrical
       power, telecommunications, emergency services, air
       traffic control, water systems, chemical facilities,
       etc. . . . However, cyberterrorism is not likely to
       occur in a vacuum. It will most likely be
       accompanied by a simultaneous physical attack
       against civilian population centers, where the loss
       of those critical services will significantly
       complicate search and rescue efforts."
