@kawaiipunk:

Currently our SSL Labs certs are only getting a B:

https://www.ssllabs.com/ssltest/analyze.html?d=autonomic.zone&hideResults=on
https://www.ssllabs.com/ssltest/analyze.html?d=git.autonomic.zone&hideResults=on

The two main issues are:

This server does not support Forward Secrecy with the reference browsers. Grade capped to B. MORE INFO »
This server supports TLS 1.0 and TLS 1.1. Grade capped to B.

We should add config options for improved security. Here is the Traefik docs. I feel like that page is missing details though.

We may need to look at other documentation. There are numerous blogposts.

Mozilla has some good guides too.

This is probablly what we want to be going by:
https://ssl-config.mozilla.org/#server=traefik&version=2.1.2&config=modern&guideline=5.6

Or intermediate to ensure compat with older clients:
https://ssl-config.mozilla.org/#server=traefik&version=2.1.2&config=intermediate&guideline=5.6

OK, achieved via https://git.autonomic.zone/coop-cloud/traefik/pulls/8.

Each app that wants to get the A+ rating needs to add the following labels to their compose.yml configuration so as to hook into Traefiks magic SSL configuration:

- "traefik.http.routers.traefik.tls.options=default@file"
- "traefik.http.routers.traefik.middlewares=security@file"

I have enabled that for https://autonomic.zone now.

I'm gonna close this off and add some follow up tickets.
