Database Security — The Database Defense Stack

A hands-on mid-level course that secures the databases behind a payments platform. Work the database defense stack - eight layers: Access Control, Authentication, Encryption, Network Isolation, Query Defense, Auditing, Backup & Recovery, and Monitoring - applying least privilege, TDE, private networking, parameterized queries, and audit logging across PostgreSQL, MySQL, and SQL Server. Strictly defensive. Four hands-on activities in every lesson.

What you'll learn

• Grant least-privilege access and authenticate database users strongly.
• Encrypt data at rest and in transit and isolate the database network.
• Stop injection with parameterized queries and audit sensitive access.
• Secure backups and monitor for anomalous database activity.
