Hi Mikael,
This document is fantastic (more so that it has been built in English!), thanks for pointing it out! There is a lot of information out there nowadays, some of it good, some of it bad - but it's not easy to find such hidden gems.
With the risk of sounding ungrateful and pedantic, I have one small issue with the website it's hosted on though, considering we're on the topic of security, MITM and best practices: the website is only available via HTTP and it's running an older version of Wordpress. Upon trying to access it via HTTPS, the certificate offered is for
interlan.se and the page is some admin login for Halon SP (whatever that is).
