I’ve seen this listing Windows as the answer, which is also wrong. Bob, patching has nothing to do with ports being opened. It’s talking about firewalls and other preventative measures at that point. Also, nmap can’t guess the OS here, so that takes the OS answers invalid. I don’t like this question, as it does not include the actual command used, and I’m sure a diagram or something is missing from the question.
This assumes that if you don’t see somethings as ‘open|filtered’ or ‘filtered’, that there is no type of protections before the server, it’s just wide open for ports scanning and icmp messages back are not blocked either. You’d probably try to banner grab and enumerate to guess the OS at this stage (which is another question similar to this you might find) but they’re not asking you that.
