An electronic device is protected from unauthorized access by use of a security wrap having a security screen (26) connected to an alarm circuit (17) of the electronic device. The security screen (26) has a pair of screen terminals (48) interconnected by a conductor (46). The conductor (46) is formed on a substrate (22). The substrate (22) is arranged such that attempts to remove the security wrap will result in the substrate (22) being torn and the conductor (46) being damaged or broken whereby the resistance of the conductive path formed by the conductor (46) changes to indicate an alarm condition. |
