This is why I pay money to IPVM. Very well done. Do you think there will ever be a Cybersecurity for Access Control Guide? We're actually working a lot of these things into our security specifications.
We are not opposed to doing an access guide at all, but releasing one is not imminent.
However, the good news is that many of the recommendations here apply to IP access as well. Disabling unused switch ports, turning off Telnet/ SSH/ FTP, using VLANs, and using strong (non-default!) passwords is good practice for access too.
The "Dahua Best Practices" link returns a 404 error, "Page Not Found" message. Go To Homepage>Support>Cybersecurity will get one to the desired destination. I do highly recommend those who want a decent chuckle to click the link above in this article as Dahua's typed message above the search box should do the trick. Enjoy!
