Abstract

The present invention provides a security protection method, system, device and readable storage medium for terminal equipment. The terminal equipment goes online and obtains the IP and equipment fingerprint information of the terminal equipment; If the device fingerprint information corresponding to the IP matches the device fingerprint information and the IP in the fingerprint reference database, it is judged that the identity of the terminal device is legal, and the terminal device is allowed to connect. If the device fingerprint information corresponding to the IP does not match the fingerprint information and IP in the fingerprint reference database, the terminal device corresponding to the IP is added to the blacklist to block the device from accessing the Internet and give an early warning. The network security is further strengthened by means of device fingerprinting, and devices with illegal intrusion and MAC counterfeiting are also found. The device fingerprinting method basically has no effect on system performance, and can resist some network penetration attacks.

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...
