Abstract
A method of protecting from modification computer apparatus comprising a plurality of functional modules by monitoring the configuration of functional modules within the computer apparatus. The method comprises: storing a module configuration of the computer apparatus; and checking the actual module configuration against the stored module configuration, and inhibiting function of the computer apparatus if the actual module configuration does not satisfactorily match the stored module configuration. Advantageously, the module configuration is stored on a security token, such as a smart card.
