Database Encryption
Database encryption is a security technique that transforms data stored in databases into an unreadable format using cryptographic algorithms, protecting it from unauthorized access. It involves encrypting data at rest (stored on disk), in transit (during network transmission), or in use (during processing). This ensures confidentiality and compliance with data protection regulations like GDPR or HIPAA.
Developers should implement database encryption when handling sensitive information such as personal data, financial records, or healthcare information to prevent data breaches and meet legal requirements. It is crucial for applications in finance, healthcare, and e-commerce to secure data against threats like hacking or insider attacks, especially in cloud environments or multi-tenant databases.
