Hi folks,
I'm new to debian and linux in general.
I have an old touch screen laptop that I recently installed debian on. I followed this tutorial at first as a proof of concept for pi hole and it worked great https://www.youtube.com/watch?v=roYduABVjo8
The main issue is I don't fully understand networking or linux and have some security concerns:
1. Does setting up a DNS server server like this cause any security vulnerabilities for the network? more so than normal operation?
2. If I'm logged in as the main user/leave the PC logged in running all the time, can anyone connect to it and wreak havoc on my network?
3. Is using sudo over su the better way to go for security in this config?
4. Is there a way to totally block remote logins/remote use so only I can control the server at the physical location?
Sorry if these questions are rudimentary, I am just very keen on getting some insight on how linux works.
Kind regards
