A security device for blocking a computer port such as a Universal Serial Bus (USB) port comprises a connector member 110 for fitting inside a USB port, wedge shaped projections 130 for securing the connector member to the USB port and a frangible (breakable) fascia 120. An attempt by a user to gain unauthorised access to the USB port by tampering with the device results in the fascia breaking off. The loss of the fascia provides clear evidence of tampering during a subsequent security audit. The fascia may be colour contrasted with the connector member to make unauthorised access readily visible during the audit. The device may be fitted with an identifier (600, fig. 6) and may include an RFID tag. A restrainer (1020, 1021, 1022, fig. 10) may be fitted to the device in order to prevent unauthorised disconnection of a peripheral such as a keyboard from a neighbouring port. The restrainer may be a steel wire in conjunction with a lead crimp to form a noose around the keyboard USB plug, or alternatively a cable tie may be used. |
