Guideline for a healthy information system v.2.0 (EN)

/STANDARD
Implement a secure access gateway to the Internet : websites hosting malware, the downloading of "infected" files and, consequently, the possibility of devices being compromised, leaking of sensitive data, etc. To secure this use, it is therefore essential that the users’ devices do not have direct network access to the Internet. 

This is why it is advisable to implement a secure Internet access gateway, including, as a minimum, a firewall as close to the Internet access as possible to filter the connections and a proxy server with different security mechanisms. This ensures users are authenticated and requests are logged.
