A method for detecting an attempted attack on a security system. In one preferred embodiment of the present invention, the method includes the step of retrieving a parameter from a hardware system, wherein the parameter changes during an operation of the hardware system. Then, comparing the retrieved parameter with a previously stored parameter; and, detecting a lack of change between the retrieved parameter and the previously stored parameter. An apparatus and an article of manufacture for detecting an attempted attack on a security system is also disclosed.
