Production Security Practices

Introduction

A consolidated security checklist for production DBs — every box must be checked before any sensitive workload goes live.

Understanding the topic

Core concepts to understand:

• Parameterized queries everywhere.
• Least privilege roles per service.
• TLS in transit, encryption at rest.
• Secrets in a vault, rotated.
• Audit + alerting on sensitive actions.
• Backups tested monthly.
• Network isolation (VPC, no public IP).
• Patch + minor-version upgrades on a schedule.

Syntax reference

Visual workflow / architecture:

Production DB Hardening
 □ TLS + at-rest encryption
 □ Per-service roles (least privilege)
 □ Vaulted secrets, rotated
 □ Audit log, alerts
 □ Backups + restore drills
 □ Private network only
 □ Patch policy
 □ DR runbook

Real-world use

Compliance audits (SOC 2, PCI, HIPAA) walk through this exact checklist. Treat it as the bare minimum, not the goal.

Best practices

• Automate the checklist via IaC.
• Enforce reviews on schema/perm changes.
• Run incident drills at least quarterly.
