Well, You al might find this interesting too:
E-mail filters are great for stemming the flow of unwanted
pornography and ads, but are they too good? We here at the
InformationWeek Daily last week got a peek at one possible filter
future when hundreds of our newsletters were bounced back because
of a story we wrote.
Software at Nortel Networks, Motorola, and Citicorp scanned our
March 7 Daily and said "no, thanks." And while we'd love to tell
you about the offending content, we really want loyal readers at
those companies to get this edition, too. Let's just say that one
of the words rhymes with "fire us." The story also mentioned,
shall we say, the L*ve B*g.
John Pescatore, a Gartner analyst, says even individual
characters and character strings are spooking the watchdogs. The
problem is that filters--increasingly common components in our
lives--are too unsophisticated, Pescatore says. Most see no
difference between a newsletter story about "uncouth coding" and
real, live "unrequested malicious programming," if you get our drift.
The solution is behavioral filters, or software that doesn't just
scan E-mail; it watches what it does or what its attachments do
once activated and (presumably) before any damage is done. "It's
almost like we are becoming Web psychologists," says Pete
Lindstrom, a Hurwitz Group analyst. The good news is that
behavioral software is already out from companies such as Finjan
Software, Pelican Security, Aladdin Knowledge Systems, and Okena,
he says.
The bad news is that IS departments literally don't know what
they're missing when using more dogmatic filters, says Tom
Bartel, Web-design director of E-mail-distribution house
MessageMedia Inc. In the meantime, bear with us when you read
sometimes-cryptic stories about "criminal cracker products" like
the most recent "rhymes-with-rude wife" outbreak. - Jim Nash
