Abstract
Database security protection, database backup and disaster recovery are important tasks for all colleges and universities to ensure the safe and stable operation of information systems. Based on the operating environment of the Oracle production database in China University of Geosciences (Beijing), combined with the practical operation and maintenance experience, this paper provides a design and implementation case of Oracle database security protection system and disaster recovery architecture. The network security protection architecture of the three-layer firewall and fortress machine, the detection and repair of security vulnerabilities, the management of system accounts and permissions, data encryption and database audit constitute the security protection system of the database. Oracle RAC (Real Application Clusters), Oracle DataGuard, redundant backup management and backup recovery constitute the disaster recovery architecture of the database. The case has practical significance for database operation and maintenance management in other colleges and universities.
Highlights
With the rapid development of information technology in colleges and universities, the teaching, scientific research and management of colleges and universities are increasingly dependent on the information platform

The database is the foundation of the information platform, so ensuring the safe and stable operation of the database is the key to the normal operation of the information platform
Summary
With the rapid development of information technology in colleges and universities, the teaching, scientific research and management of colleges and universities are increasingly dependent on the information platform. A lot of research and practice on the security protection and disaster recovery of the Oracle database server have been done in many universities. Based on the operating environment of the Oracle production database in China University of Geosciences (Beijing), combined with the practical operation and maintenance experience, this paper provides a design and implementation case of Oracle database security protection system and disaster recovery architecture. In this case, a three-layer firewall is used, and the fortress machine and database audit are added for security reinforcement. On the data disaster recovery level, a redundant database recovery environment is constructed based on the simultaneous use of Oracle RAC and Oracle DG
