摘要
A system and method is disclosed for identification and response to an unauthorized transmission to a networked critical system. The invention employs a pre-defined parameter which matches trusted sources with defined destinations to enable secure access to the networked critical system. Once the method receives a transmission to the destination, it filters the transmissions based on specific architecture constraints. Should the transmission survive, the method continues with a plurality of layers of system level checks to verify the source matches the pre-defined parameter of a trusted source. Should the transmission fail any of the layers of system level checks, the method provides an appropriate response. Once the transmission survives, the method continuously monitors the data stream for possible threats and allows access the transmission to reach the destination and the networked critical system.
