INTRUSION PREVENTION SYSTEM (IPS) MODE FOR A MALWARE DETECTION SYSTEM

Intrusion prevention system (IPS) mode is provided for a malware detection system. At least one staging server is provided for intercepting an incoming electronic message, making a copy of the intercepted incoming electronic message, and holding the intercepted incoming electronic message until an analysis of the copy of the intercepted incoming electronic message has been completed or until a timeout threshold has been exceeded. A malware detection system is coupled to the at least one staging server. The at least one malware detection system includes at least one decomposition server for receiving the copy of the intercepted incoming electronic message and processing the copy of the intercepted incoming electronic message to detect malware. Multiple mail queues, e.g., incoming, timeout, jail, decomposition, and outgoing, are used to manage message flows and delay messages while malware analysis is performed.
