Databases Hold Crown Jewels
Customer data, financial records, intellectual property—databases contain your most valuable assets.
Access Control
Strong authentication for all access. Role-based permissions. Principle of least privilege. Regular access reviews.
Encryption
Encryption at rest protects stored data. Transparent Data Encryption is transparent to apps. Column-level encryption for sensitive fields. Key management is critical.
Network Security
Database firewalls filter traffic. Network segmentation isolates databases. VPN for remote access. No direct internet exposure.
Activity Monitoring
Audit logs capture all access. Anomaly detection identifies threats. Real-time alerting for suspicious activity. Forensic capabilities for investigation.
Patching and Updates
Regular security patches. Testing before production deployment. Emergency patching procedures. Version management.
SQL Injection Prevention
Parameterized queries eliminate injection. Input validation adds layer. Least privilege limits damage. Web Application Firewall provides defense.
Backup Security
Encrypted backups protect data. Separate credentials for backup systems. Regular restore testing. Offsite storage with protection.
Database Types
Relational databases: MySQL, PostgreSQL, SQL Server. NoSQL: MongoDB, Cassandra. Cloud managed: RDS, Cloud SQL. Specialized: Redis, Elasticsearch.
Security Testing
Vulnerability scans regularly. Penetration testing for critical systems. Configuration audits against benchmarks. Code review for database access.
