Problems solved by technology

Since the penetration of the industrial control system of the power grid often starts from the edge nodes of the entire network architecture (that is, the host node of the plant station system), the security prevention of the edge nodes is still relatively weak, resulting in the insecurity of the entire power grid

Abstract

The invention relates to a security defense method and device for a power grid plant station host, computer equipment, a storage medium and a computer program product. According to the invention, security defense of an edge node (i.e., a plant station host) level in the power network can be realized, and the security of the power network is further improved. The method comprises the steps of collecting input and output logs; performing static network security feature recognition on the input and output logs to obtain a static feature recognition result; performing dynamic behavior analysis on the input and output logs to obtain a dynamic behavior analysis result; and sending the static feature recognition result and the dynamic behavior analysis result to a master station system.

Description

technical field [0001] The present application relates to the technical field of network security, in particular to a security defense method, device, computer equipment, storage medium and computer program product for power grid plant hosts. Background technique [0002] With the development of information technology, network security has been paid more and more attention. In the power network, if the power network is attacked by hackers, it may cause the collapse of the power grid in an entire area, causing huge economic losses. [0003] The industrial control network is the network part of the industrial control system. It is a communication network that organizes various production processes and automation control systems in the factory through various communication devices. For the power grid, the communication network in the power grid is the industrial control network. The power grid industrial control network also includes multiple plant station systems. The plant s...
