Abstract:
A method of providing secure access from a user system at a user location to a target system at a secure location, said method allowing access from said user location to a plurality of target locations including said secure location, wherein said secure access is provided on a telecommunication network capable of supporting connectivity to said plurality of target locations simultaneously from said user location, said method comprising the steps of:(a) configuring said telecommunication network to provide connectivity from said user location to each of said plurality of target locations, wherein said connectivity is provided via a switch at said user location, said switch having a first switch setting corresponding to said target system at said secure location and at least one other switch setting corresponding to said plurality of target locations other than said secure location; (b) enabling a user to select a desired target location to which access is to be provided; (c) disabling the connectivity between said user location and all of said plurality of target locations except said desired target location selected in step (b) by having said switch at said first switch setting if said desired target location corresponds to said secure location; and (d) transferring data between said user system and said desired target location to provide a virtual circuit between said user location and said desired target location, wherein said transferred data provides basis for access of said target system from said user system, wherein the disabling of step (c) ensures that said access from said user system to said target system at said desired secure location is secure.
