Database Security and Performance Optimization in Modern Information Systems

Abstract

Database systems form the backbone of modern information systems by storing and managing critical organizational data. As the volume and complexity of digital information continue to grow, ensuring database security while maintaining high performance has become a strategic priority. Organizations face increasing threats such as unauthorized access, SQL injection, data breaches, ransomware, insider attacks, and system failures. At the same time, they must optimize database performance to support real-time applications, cloud services, and large-scale analytics. This paper discusses key database security mechanisms, performance optimization techniques, emerging challenges, and future directions for secure and efficient database management.
