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.
