TLS dan transport for PostgreSQL
high5 checks
TLS protects credentials and session cookies in transit. A valid chain, a modern protocol and no downgrade path are the baseline.
What PostgreSQL must have
- Certificate chain validates against public trust stores
- Expiry monitored automatically, no manual renewal
- TLS 1.2 and 1.3 only; 1.0 and 1.1 disabled
- HTTP redirects to HTTPS with a permanent redirect
- No mixed content on any page
How to fix it
- 1Enable auto-renewal with your host or CDN and alert at 21 days remaining
- 2Force HTTPS at the edge and remove any route that serves plain HTTP
PostgreSQL context
Relational database with strong SQL compliance.
Keep 5432 firewalled, require TLS, and never let the app connect as a superuser.
