A 5G network security risk assessment method

Abstract

The invention provides a 5G (5th-generation) network security risk assessment method, which can objectively reflect the 5G network security situation. The method comprises the steps of identifying assets in a network; assessing the attribute values of the assets in the aspects of confidentiality, integrity, availability, multiaspect trustworthiness and auditability, wherein the network is a 5G network; identifying the vulnerabilities in the network; assessing the influence values of the vulnerabilities on the aspects of confidentiality, integrity, availability, multiaspect trustworthiness and auditability; calculating the loss value of the network after the attack by an attacker according to the attribute values and the influence values obtained through assessment; calculating the attacked probability of the vulnerabilities in the network; calculating the security risk value of the network according to the loss value of the network after the attack by the attacker and the vulnerability attacked probability obtained through calculation. The 5G network security risk assessment method is applicable to the technical field of 5G network security.

Description

technical field [0001] The invention relates to the technical field of 5G network security, in particular to a 5G network security risk assessment method. Background technique [0002] The 5G network shoulders the heavy responsibility of meeting the new needs of future communications. It will be an important cornerstone for comprehensive connectivity and mobile informatization, and will change our lives through many new application methods. Obviously, under the new communication requirements and application environment, 5G networks will naturally have significantly different requirements in terms of security. [0003] In the traditional mobile communication network, the main communication purpose of people is to communicate with other terminals by voice, short message or video. People enjoy fast Internet services and use mobile APPs through smart phones. For the 5G era, mobile communication networks will not only serve individual consumers, but more importantly, will serve ...
