Abstract

The invention provides a safety protection method, system and device for a terminal device and a readable storage medium. The method comprises the steps that the terminal device is online, and the IPand device fingerprint information of the terminal device is acquired; comparing and judging the equipment fingerprint information corresponding to the IP with the equipment fingerprint information and the IP in a fingerprint reference library; if the equipment fingerprint information corresponding to the IP is matched with the equipment fingerprint information and the IP in a fingerprint reference library, judging that the identity of the terminal equipment is legal, and allowing the terminal equipment to access a power information network; If the equipment fingerprint information corresponding to the IP is not matched with the fingerprint information and the IP in the fingerprint reference library, adding the terminal equipment corresponding to the IP into a blacklist, blocking the equipment from surfing the Internet, and carrying out early warning. The network safety is further reinforced through a device fingerprint mode, illegal invasion and MAC counterfeit devices are discovered,the device fingerprint mode basically has no influence on the system performance, and a part of network penetration attacks can be resisted.

Description

technical field [0001] The present invention relates to the technical field of terminal equipment security protection, in particular to a terminal equipment security protection method, system, equipment and readable storage medium. Background technique [0002] With the continuous advancement of the ubiquitous power Internet of Things construction, a large number of terminal devices are connected to the power information network, and illegal devices are counterfeited to break the system, which brings huge hidden dangers to the security management and control of the information network. [0003] At present, Radius authentication is widely used for information network security management and control. RADIUS authentication is a distributed client / server system, which realizes a secure network and opposes unauthenticated access. The specific implementation method is to open the protocol authentication mode on the switch side, and realize the information collection and verificati...
