A system and method for providing external data-signal isolation, and signal-level information-preserving-data-transformations, to enable safe, operationally efficient, information sharing between protected information systems and networks and external, potentially hostile, information systems and networks which neutralizes any imbedded hostile executable codes such as viruses that may be in data-signals incoming from the external systems and networks. The system and method prevent untransformed external data-signals from entering protected systems and/or networks using an intermediate screen which is a computer hardware device. The intermediate screen is deployed between the protected systems and external systems and is used to process all incoming signals from the external system to obtain transformed data sets from which information is extracted before it is passed to the protected system.
A method of enabling information exchange between a protected system and an external information source wherein the information is contained in an initial data set carried by a signal while preventing any hostile data carried by the signal and which is executable in a first format of the signal from reaching the protected system in an executable format, including the steps of:
A system for enabling information exchange between a protected system and an external information source wherein the information is contained in an initial data set carried by a signal while preventing any hostile data carried by the signal and which is executable in a first format of the signal from reaching the protected system in an executable format, the system including:
A method of enabling secure information exchange between a protected system and an external information source on the internet wherein the information is contained in an initial data set carried by a signal while preventing any hostile data carried by the signal and which is executable in a first format of the signal from reaching the protected system in an executable format, including the steps of;
