Abstract
Access point network equipment has communication ports that allow communications with other network components. Open ports can be accessed to the network by unauthorized devices creating a security breach. Filling the open ports with locking plugs can create a physical barrier preventing unauthorized connections to the access point network equipment. Two or more pairs of conductors in the locking plugs can be electrically coupled so that link down events can be detected by tamper detection software running on the access point network equipment. When a link down events is detected the tamper detection software can perform various possible security actions to protect the network.
