[0002] Computer network security refers to the use of network management controls and technical measures to ensure that the confidentiality, integrity and availability of data are protected in a network environment. Computer network security includes two aspects, namely physical security and logical security. Physical security means that system equipment and related facilities are physically protected from damage and loss. Logical security includes the integrity, confidentiality and availability of information. One of the existing ways to quickly disconnect the network for computer network security is to directly unplug the network cable, that is, unplug the cable end from the network cable interface.
