An electronic device is protected from unauthorized access by use of a security wrap which comprises at least a substrate, a security screen, a layer of adhesive and decoy pattern. The security screen is disposed over one side of the substrate and includes a pair of screen terminals and a conductive path between the pair of screen terminals. The layer of adhesive bonds the first side of the substrate to the electronic component with the security screen sandwiched there between. The decoy pattern is at least partially impervious to X-ray and overlays said security screen.
