Safety immune system for intelligent power distribution terminal

Abstract

The invention discloses a security immune system for an intelligent power distribution terminal, and belongs to the field of power distribution terminal immune systems. The security immune system for the intelligent power distribution terminal adopts a security access technology based on a block chain technology to modify a system kernel; a security immune system aiming at the intelligent power distribution terminal is developed to ensure that a power distribution network is immune to attacks of malicious codes, viruses and the like, the coping capacity of the power grid to novel attacks is improved, safe and stable operation of the power grid is ensured, a mandatory access control model of a kernel-level HOOK technology is established, resource calling of malicious attacks is blocked and controlled, and the safety of the power distribution network is improved. According to the technical scheme, a white list ACL control method based on the block chain technology is established, the ACL tamper-proof and anti-repudiation ability is enhanced, the traditional security protection technology is not adopted, and the method naturally has the ability of resisting zero-day attacks, so that an operation system cannot be controlled, large-scale faults are avoided, and the security of the power Internet of Things is effectively guaranteed.

Description

A Safe Immune System for Intelligent Distribution Terminals technical field The present invention relates to the field of power distribution terminal immune system, more specifically, to a kind of intelligent power distribution terminal Safe immune system. Background technique With the deep integration of industrialization and informatization in the State Grid Corporation, and the rapid development of network communication technology in recent years [0002] rapid development. With the vigorous development of network applications, the openness of the network also brings huge security risks. With the network attack The trend of attack organization and nationalization is becoming more and more obvious, and the security risks faced by important information systems and industrial control fields are still high. However, the attack methods are becoming more and more complex, and the relatively lagging feature detection method currently used to prevent and control the sprea...

Problems solved by technology

Traditional embedded transmission and distribution terminal operating systems generally have security problems such as fragile access control, privileged users, and the inability to judge the legality and compliance of system commands. It is urgent to study a virus based on intelligent power distribution integrated terminals Security immune technology to realize endogenous security of IoT terminal system

[0005] Power smart terminals are often mass-produced by manufacturers and installed outdoors. Their functions are to ensure the power transmission, distribution, and transformation of basic power supply facilities. Once they are maliciously attacked, they may cause serious damage to the power system. Even caused large-scale power outages and paralyzed the power grid

Its potential safety hazards include: the device has an initialization password when it leaves the factory, which may be obtained and used, and the software configuration is the same. Once a vulnerability is found in one of the devices, it means that the same batch of products has the same vulnerability. Outdoor equipment is usually left unattended, and the equipment has common debugging ports such as Ethernet ports and serial ports, which are easy to be debugged by physical contact
