In view of the growing demand for mobile office remote access in meteorological departments, this paper studies the application of VPN access technology and remote secure desktop, integrates existing remote access methods, and optimizes mobile office access platform. This paper analyses the specific needs and network structure of meteorological service, studies the secure desktop based on SL VPN, provides a secure virtual working environment for remote access users, restricts users'access to resources within the secure desktop, protects the security of business system data, and solves security issues such as sensitive data leakage, transmission and copy. To study and build a special security zone for meteorology, to divide the rights and privileges, to ensure the security of important internal application systems, and to conveniently share other resources in the meteorological intranet, to provide safe and efficient remote access services for mobile office and meteorological emergency personnel to access the resources in the meteorological Intranet.
