154+
## 🎓 Understanding the Security Improvements
155+
156+
### Before Hardening ❌
157+
```
158+
Internet → SQL Server (0.0.0.0/0 access)
159+
→ Key Vault (no network restrictions)
160+
→ Containers (running as root)
161+
→ Secrets (hardcoded in git)
162+
```
163+
164+
### After Hardening ✅
165+
```
166+
Internet ╳ SQL Server (private only)
167+
╳ Key Vault (private + RBAC)
168+
✓ Containers (non-root + security contexts)
169+
✓ Secrets (environment variables)
170+
✓ Audit Logs (90-day retention)
171+
✓ Automated Scanning (CI/CD integrated)
172+
```
173+
