Problems solved by technology

[0004] It can be seen that the existing technology only evaluates the risk of the information system from the two dimensions of the terminal and the server, and only considers the security incidents that occur in the information system during the evaluation process, ignoring the threat factors in the information system, so the existing Technology cannot accurately assess the risk status of information systems

Abstract

The embodiment of the invention discloses an information security risk assessment method and device, equipment and a storage medium. The method comprises the following steps that: 1, the asset value and the vulnerability value of an information system are determined respectively; each influence factor threatening the information system is decomposed into a plurality of hierarchies according to different information attributes, a threat value of the information system is determined according to the relevance between the influence factors in the adjacent hierarchies, and the vulnerability valueis used for describing the weakness degree of the assets in the aspect of security; the risk possibility of the information system is calculated according to the threat value and the vulnerability value, and the risk consequence possibility of the information system is calculated according to the vulnerability value and the asset value; and an information security risk value of the information system is determined according to the risk possibility and the risk consequence possibility. According to the technical scheme of the embodiment of the invention, the security risk state of the information system can be accurately evaluated.

Description

technical field [0001] The present application relates to the technical field of information security, in particular to an information security risk assessment method, device, equipment and computer-readable storage medium. Background technique [0002] With the rapid development of network technology, a large number of information systems and related products are deployed in various industries, and the security issues faced by information systems have become the focus of attention in the industry. [0003] In order to assess the risk of information systems, the existing technology proposes a risk assessment method based on asset security events. Specifically, it is necessary to calculate the risk score and loss score of the server according to the number and probability of different security events occurring in the server, and according to the terminal Calculate the security score and loss score of the terminal based on the number of vulnerabilities, security baselines and ...
