Database Security Basics
Why Database Security Matters
A database holds an organization's most valuable data. Security protects it from unauthorized access, theft and corruption.
Key Security Measures
- Authentication — strong passwords, separate user accounts.
- Authorization — least-privilege GRANTs.
- Encryption — protect data at rest and in transit (SSL).
- Prepared statements — prevent SQL injection.
- Backups — recover from attacks or failures.
Summary
- Security = authentication, authorization, encryption, injection prevention, backups.
- Give minimum privileges and always use prepared statements.
