Abstract
A method for controlling physical security of a computer removably coupled to a network wherein 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 with a frequency preset by the security administrator. Techniques are provided in the client computer to inhibit breach of the security of the timer.
Claims4
A method for controlling physical security of a slave device in a network having an administrator device and a slave device having an embedded timer, said method comprising the steps, in said slave, of:
- sensing whether said slave device is present within an authorized network;
- thereupon
- allowing operation of said slave device for a designated period delimited by a timeout of said timer;
- only upon receipt of a timer reset signal from an authorized administrator device of said authorized network by said slave device, resetting a timer register of said timer to allow continued operation of said slave device;
- otherwise
- causing said slave device to disable itself such that the slave device is rendered nonfunctional absent further authorized external intervention.
