Abstract

In a method and system for managing concurrent access to multiple resources, resources are assigned to sets in such a way that it is safe to concurrently access any combination of resources in a resource set. For each resource set, a virtual machine is defined and associated with the resource set. An application is assigned to a virtual machine. When an application requests access to a resource not in the application's virtual machine, access control lists are consulted to determine whether the access should be allowed, given the other resources already accessed by the application.

Description

[0001] This application is a divisional of a co-pending U.S. patent application Ser. No. 09 / 946,659, filed Sep. 5, 2001, and entitled “METHODS AND SYSTEMS OF MANAGING CONCURRENT ACCESS TO MULTIPLE RESOURCES”.TECHNICAL FIELD

[0002] This invention is related in general to the art of managing access to multiple resources, and, more particularly, to a method of managing concurrent access to multiple resources. BACKGROUND OF THE INVENTION

[0003] Restricting network access to only authenticated users protects confidential information on the network from being compromised. Restricting access using common user authentication techniques, however, does not address network integrity issues in situations when a computer connects to more than one network. FIG. 1 shows a typical setup of a computer 100 connected to a private corporate network 141 via an Ethernet card 111 and to the public Internet 161 via a modem 112. An application 120 running on the computer has access to the two networks. This...
