Not really -- security by obscurity is a re-statement of the idea that the security mechanism shouldn&#x27;t need to be secret for the security to have meaning.  You&#x27;re allowed to have secret data, just not secret mechanism.<p>And relying on what looks like secret data (changing the SSH port) where the number of bits of entropy is low enough that it&#x27;s plausible to try them all (16) probably still counts as security by obscurity -- it might hide you from many attackers, but it&#x27;s not enough to make you secure.<p>Relying on data that&#x27;s not actually secret, just hard to find, is just insecure.
