<p>A method of the present invention includes a network security system (10) that has a single point of access control (24) to a source computer system (20). The network security system (10) provides various mechanisms for securing access to source computer systems (20) that includes generating single-use encryption keys, generating random port assignments for communication between devices, an asynchronous message protocol used in the security system and utilizing various levels of transaction tables to help secure and manage security parameters of the system. More particularly, the present invention provides a method for securing access to a plurality of computers (20) connected via a network (26, or 22). An indication is received that a first user of a first computer program module of a first computer (16) desires to communicate with a destination computer system (20). When this indication is received, a message is directed to a security computer system (24). The security computer system (24) determines whether the first user of the first computer (16) is authorized to access the destination computer program module of the destination computer system (20). If the security computer system (24) determines that the first user is authorized to access the destination computer system (20), the security computer system (24) sets up a communication protocol between the first computer program module and the destination computer program module.</p> |
