ABSTRACT:
BACKGROUND OF THE INVENTION
This invention relates to security of computers on a network, including for example a wireless network of portable computers in a classroom environment, a wired local area network, a cable television system with settop boxes containing computing devices, a telephone system, either wireless or wired, having computer controlled devices coupled thereto, such as cellular telephones, computers and the like, and a satellite-based network.
One of the security concerns of valuable property, such as a computer, is theft. A network can be used to enhance security and prevent theft of the property, especially if the property has sufficient intelligence to participate in its own security without the knowledge of the thief.
SUMMARY OF THE INVENTION
In a network, a method is provided for controlling physical security of a computer removably coupled to a network. According to the invention, a security administrator associated with a server invokes a timer in a client computer and disables the client computer if the computer is not operated within the network within a time period preset by the security administrator. Techniques are provided in the client computer to inhibit breach of the security of the timer.
The invention will be better understood by reference to the following detailed description in connection with the accompanying drawings.
