One of the most prominent and advanced threats to government networks is advanced delivery and execution of zero-day malware. The adversary effectively utilizes technology and has enhanced their ability to create and deliver highly effective unknown or zero-day malware through advanced persistent threats (APTs). To improve defense and resilience, governments are creating their own private threat intelligence clouds based on Palo Alto Networks WildFire™. This architecture enables immediate analysis of the unknown threats and swiftly pushes prevention to all of the physical and virtual Palo Alto Networks platforms from data center to endpoint within the network.
