ABSTRACT:
On a network, access to individual data processing systems is remotely controlled from a host data processing system. A security request is provided at the host data processing system. The security request specifies the target data processing systems, whether those systems are to be locked or unlocked, the peripherals of the specified data processing systems that are affected and a password. The security request is communicated to all data processing systems in communication with the host data processing system. Each data processing system processes the security request to determine if it is a target. If so, then a lock status of a target set of data processing systems is changed in response to the security request. The change in lock status of the target set of data processing systems either facilitates or prohibits use of the target set of data processing systems.
