ABSTRACT:
Accordingly, a computer implemented method, uniquely programmed computer system, and article of manufacture embodying computer readable program means all allow a customer on an external network to initiate an authorized business transaction utilizing internal business resources on an internal network without violating security firewalls. Specifically, the method directs an internal computer system to allow an external computer system to initiate a transaction request using internal resources without violating a security firewall between the internal computer system and the external computer system. The method includes a first step of authenticating a connection initiated by the internal computer system between the internal computer system and the external computer system, thereby establishing an authenticated connection. The second step includes calling by the external computer system a transaction request received by the external computer system. In response to calling the transaction request, the third step includes creating by the external computer system a string comprising the transaction request, arguments, and process environment variables for executing the transaction request. The fourth step includes transmitting by the external computer system the string to the internal computer system through the authenticated connection. The fifth step includes verifying by the internal computer system the transaction request. The sixth step includes recreating by the internal computer system the original process environment. The final step includes executing by the internal computer system the transaction request, thereby generating an output.
