Practice of Using Threat Intelligence-Enabled DNS to Enhance Hospital Network Security
Objective To enhance hospital network security using threat intelligence and DNS. Methods Configure a threat intelligence-enabled secure DNS strategy at the hospital's internet exit,allowing hospital terminals and internet information systems to access the internet through the secure DNS. Results After implementing the secure DNS,the hospital has achieved a 100% interception rate for outbound malicious domain access. It can effectively intercept and block advanced persistent threats. Conclusion By utilizing a secure DNS based on threat intelligence,the hospital has strengthened its ability to locate security threats,shortened the time and cost of threat response. It is of reference significance for strengthening hospital network security and improving the overall level of hospital security.
