Relational Database Security
Relational Database Security is a set of principles, practices, and technologies focused on protecting data stored in relational database management systems (RDBMS) from unauthorized access, corruption, or loss. It encompasses authentication, authorization, encryption, auditing, and vulnerability management to ensure data confidentiality, integrity, and availability. This concept applies to systems like MySQL, PostgreSQL, Oracle, and SQL Server.
Developers should learn Relational Database Security to safeguard sensitive data such as user credentials, financial records, and personal information in applications, especially in industries like finance, healthcare, and e-commerce where data breaches can lead to legal penalties and reputational damage. It is essential for implementing compliance with regulations like GDPR, HIPAA, or PCI-DSS, and for preventing common threats like SQL injection, data leaks, and insider attacks.
