content
security
is
the
main
concern
of
network
administrators
as
most
of
today's
threats
are
embedded
in
the
content

the
data
exchanged
between
systems
and
users.

order
to
protect
against
threats
a
group
of
tools
are
needed
to
provide
filtering
capabilities
against
spam
and
virus
mail. Intrusion
Detection
&
Prevention

and
firewall
functions
create
a defense
against hackers
and
blaster
attacks
from
Internet
or
Intranet.
