Abstract

The invention discloses a method and a device for startup information safety protection of a route switching device. In the method and the device, by controlling power supply circuits and reset circuits of a network switching element and / or a network transformer unit of the route switching device, the independence of each port is guaranteed on a physical level during a system startup process, the fact that interfaces cannot carry out data interaction with each other during the process is guaranteed, and therefore the safety system of the route switching device is relatively reliable.

Description

technical field [0001] The invention relates to the technical field of network security, in particular to a method and equipment for protecting startup information security of a routing switching device. Background technique [0002] With the rapid development of informatization construction, the bandwidth has become wider and wider, the network speed has doubled, and technologies such as IP voice and video have greatly enriched network applications. However, while the Internet is shortening the distance between people, viruses and hackers also come uninvited. The intelligence of viruses, rapid mutation and reproduction, the "fool" of hacking tools, and the flood-like flood trend make the information systems for enterprises and individuals vulnerable, facing the danger of paralysis or even permanent damage at any time. [0003] In existing routing and switching devices, the independence of each network interface is often configured by software. In a relatively short period...
