This article discloses a means to prevent the utilization of unauthorized dial-in ports to a computer. Access to mainframe computers by means of telephone dial-in ports provides users of those systems with substantially greater system availability and productivity. Dial-in ports, however, represent a risk to the security of programs and data stored and executed in these computers. The risk is presented by the opportunity that dial-in ports present to unauthorized users to gain access to these computing systems. The conventional solution to this problem is the use of a dial back system. Dial back systems only allow access from locations whose telephone numbers are stored on the mainframe.
