Hi Zentyal user's,
after reading the Zentyal documentation, having browsed the forum, I allow myself to come and ask my questions in this section.
Having carried out an installation without problems, today I want to secure this installation, and this by securing ports 22, 80 and 389.
By consulting the forum I found how to secure port 389 without disabling it, which is not recommended, do you have any suggestions for the other ports?
I'm not looking for a ready-made solution, just advice, a choice will be made if feasible or not
Wishing you many thanks in advance for your future contributions
