Is there any point in using antivirus these days anyway? I'm open to being wrong here, but I'm under the impression that antivirus exists only to tick boxes in outdated security compliance checklists. How big of a threat are viruses compared to, say, rogue antivirus products themselves?
What happened to defense in depth with all of the layers you can introduce?
Surely if you run a Linux server, you might want a secure password for it, or better yet, key based authentication. Port knocking? Why not, throw it in there as another layer. Maybe deny authentication on an IP range basis? Why not. What about fail2ban or some other solution like that to disallow brute forcing? Sure. Or maybe require using a VPN to connect to it at all? Even better! Actually, even running your SSH server on a non-standard port will be enough to get rid of some attempts to brute force the password.
Sure, key based auth makes many of those moot points so i probably have the order of some of those steps wrong, but surely there's a lot of merit in combining whatever solutions you can to make the end result more secure, right? Hell, if you're running a web service of some sort or an application for yourself, adding basicauth in front of it at a web server level is enough to act as a safety net should the auth functionality of the actual application be broken, until you patch it.
So why should Windows be any different? If i'm stuck using that OS, i'd surely want to use whatever software is available to me to make the uphill battle towards something vaguely secure more doable, no?
