What "Zero Day" is All About
There's a lot of buzz in the security industry about "Zero Day" attack protection, but vendors differ substantially in the protection they really provide.

• Zero Day threats are new or unknown attacks for which a patch or signature has not been written
• Zero Day protection, therefore, means being protected against a new and unknown threat before the vulnerability is discovered and the exploit is created and launched

Zero day protection means being protected against a new and unknown threat during the window of vulnerability timeframe.

True Zero Day Protection is Built into the Firebox® X
The Intelligent Layered Security architecture of the Firebox X combines key security capabilities able to defend against whole classes of attacks. Some of these capabilities include:

• Protocol anomaly detection Blocks malicious traffic that does not conform to established protocol standards
• Pattern matching Flags and removes high-risk files, such as .exe and scripting files, viruses, spyware, and trojans from the system by fully inspecting the entire packet
• Behavior analysis Identifies and stops traffic from hosts exhibiting suspicious behaviors, including DoS and DDoS attacks, port scans, and address scans
