Assessment and Defense of Network Security Risks for Self-Service Terminals in the Hospital
Objective To reduce the network security risks of self-service terminal devices in the hospital,enhance the hospital's network security protection capabilities,and ensure the stable operation of information systems and the security of medical data.Methods Taking a large Grade hospital in Henan Province as an example,this paper analyzes the common security risks faced by self-service terminals and evaluates the security risks quantitatively based on the Common Vulnerability Scoring System(CVSS3.0).According to the quantitative results,the self-service terminals are classified into four categories:high risk,medium risk,low risk and no risk.Finally,strengthen security measures from the perspectives of personnel,technology and physical aspects to eliminate the medium and high risks of self-service terminal devices within the hospital.Results Complete a network security risk assessment of 948 self-services terminal devices,and reduce the number of medium and high-risk self-service terminal devices from 692 to 0 through security improvements and reinforcements.The statistical analysis of the number of self-service terminal devices with safety risks before and after rectification shows a significant difference(P<0.05).Conclusion Conducting network security risk assessments,security improvements and reinforcements on self-service terminal devices is beneficial for enhancing the hospital's network security protection level and ensuring the stable and secure operation of hospital information systems.
