Zero day attacks are a growing
threat to corporate networks, because they pass undetected through
conventional signature-based defenses. Many, if not most, systems
are vulnerable to these attacks. The actual number of infections is
staggering, and dealing with them burdens IT departments and
impacts corporate bottom lines. The corporate losses are the
criminals’ gains, as compromised systems feed an underground
cyber-economy worth millions and millions of dollars. Rather than
relying solely on signatures, businesses need a security strategy
that also includes protection from zero day attacks. This white
paper explains the mechanisms of zero day threats and shows how the
WatchGuard approach of combining application proxy firewall and
intelligent layered security provides fundamentally stronger
protection for business networks.
