I plan to run pormox on same computer with GUI. I have pfsense box separate. I will run guests for testing, opening maybe unsafe emails, browsing with privacy, run website, have mail server, note server, maybe more stuff that access from outside WAN.

I need good security against hacker and cyber attack. I will have same computer but different guest for my financial data and other important thing. What is best way tio secure my network? Here is what I think.

I have posted another topic for network set up and now I want to ask for Linux harden tips. I already read debian harden tip online and try it for chmod commands and other thing that is written about.

I also think it better install secure linux distribution and proxmox on top but it not work. So now I think install proxmox on debian or bare metal? Which is more safe when harden?

Additionally I want to know any tip or guide or anything on how make it more safe. I use it on same computer as host with GUI. Is there difference between GUI which is more or less safe? I cannot find information.

I too think keep host offline and only allow guest who need internet access to WAN. That way my main concern is hacker bread outside of guest. Because I will have websites and important data on different host then I want it to be safe as can be. How can I do it? I have little experience in Linux and am very eager to learn and quick study. Any tip or advice very appreciated. And ask me any question I will answer if it help you help me. Thank you all.
