Method and system for regulating entry of data into a protected system

A computer-based system for regulating entry of data into a protected system, the computer-based system comprising:

• a first processor configured to process and manage data for the computer-based system;
• at least one indelible memory communicatively linked with the first processor for the computer-based system;
• and
• a second processor configured to process and manage data for the protected system, wherein the second processor for the protected system is communicatively linked to the first processor for the computer-based system,
• wherein the first processor for the computer-based system is configured to:
• receive at least one parameter from the second processor, wherein the at least one parameter defines which data from a data stream can pass to the protected system;
• receive the data stream from at least one accessing system;
• filter the data stream based on the at least one parameter received from the second processor;
• and
• transmit the filtered data stream to the second processor, wherein at least one of the receiving, the filtering, and the transmitting is performed by utilizing the at least one indelible memory.

A computer-readable storage medium having stored therein computer-readable instructions, which, when loaded in and executed by a computer causes the computer to perform the steps of:

• receiving at a perimeter system at least one parameter from a protected system, wherein the at least one parameter defines which data from a data stream can pass to the protected system;
• receiving the data stream from at least one accessing system;
• filtering the data stream based on the at least one parameter received from the protected system;
• and,
• transmitting the filtered data stream to the protected system, wherein at least one of the receiving, the filtering, and the transmitting steps is performed by utilizing indelible memory.
