Abstract

The System Access Monitor (SAM) provides system security and integrity of a data base. In a computer system in which remote users have access to the computer via a phone and data set connection, it is of prime importance that the user have access to only authorized data and that he cannot issue system commands which are honored. In other words, the system honors alphanumeric questions rather than control questions.

System Access Monitor

The System Access Monitor (SAM) provides system security and integrity of a data base. In a computer system in which remote users have access to the computer via a phone and data set connection, it is of prime importance that the user have access to only authorized data and that he cannot issue system commands which are honored. In other words, the system honors alphanumeric questions rather than control questions.

The system includes a phone 2 which uses a dedicated phone access number which is processed through a data set 3 to SAM 4 via an R5232 interface. SAM is hardwired to the computer 5.

In response to the dialing of the dedicated phone number, SAM connects the user to a QUERY System in the computer which sets forth a table, including subtables, of questions the user may ask.

In the event that the user issues a system command or some other unauthorized question not found in the table or subtables, the user is locked out and informed that the system does not honor such questions.

SAM includes a microprocessor for performing its functions, and accordingly the tables and subtables may be updated by reprogramming the microprocessor memory.
