MESSAGING NEWS FEBRUARY 2010
"The problem with these
transient and dynamic
Web pages is that they
resist categorization,
which renders URL
filtering largely
ineffective. According
to Cisco Security
Intelligence Operations
(SIO), only 20 percent
of Web site addresses
can now be properly
categorized. The other
80 percent of Web site
pages are now referred to
as the "Dark Web"—that
is, Web pages that are
uncategorized, highly
dynamic or otherwise
unreachable."
