Abstract: With the digital transformation of geological exploration units and the continuous promotion of the intensive and unified construction of geological archives, it provides a new idea and platform for the management of geological archives in China. Currently, the digital construction of geological archives is advancing in an orderly manner, the business of geological exploration and geological data are moving from decentralized deployment to centralized management, and the geological archives data center has significantly promoted the development of the business of geological exploration units and effectively improved the The data center of geological archives has greatly promoted the business development of geological exploration units and effectively improved the efficiency and level of geological archives management in China, laying an important foundation for the next step of geological exploration and geological survey. However, at the same time, due to the reliance of data centers on open Internet networks, they bring convenience in application and also put forward higher requirements for security. This paper combines the functional attributes and business characteristics of the geological archives data center and constructs a set of security protection system for the geological archives data center based on the zero-trust security architecture, so that the geological archives data center can run in a safe environment and be protected from hacker attacks, viruses, Trojan horses and malicious programs.
