Database Security
Database security is a set of practices, tools, and policies designed to protect databases from unauthorized access, misuse, corruption, or theft. It encompasses measures to ensure data confidentiality, integrity, and availability, addressing threats like SQL injection, data breaches, and insider attacks. This involves implementing controls at multiple levels, including network, application, and database layers.
Developers should learn database security to build robust applications that safeguard sensitive data, comply with regulations like GDPR or HIPAA, and prevent costly breaches. It is essential for roles involving financial systems, healthcare applications, e-commerce platforms, or any system handling personal or proprietary information. Understanding security principles helps in designing secure schemas, writing safe queries, and integrating with authentication systems.
