With the deepening of information technology, risk assessment has become increasingly important in the field of information security. In view of the current situation that China lacks quantitative evaluation technology in terms of network terminal security status evaluation, this paper proposes a set of evaluation index system for network terminal security status, which covers network terminal assets, threats, vulnerabilities and other aspects. Based on the safety evaluation method, an evaluation model is established by using multi-level fuzzy comprehensive evaluation method, focusing on how to reduce human subjective factors and how to provide objective safety condition evaluation factors.
