after reading up on selfhosting for weeks now I finally decided to take the plunge today and tried setting up my own nextcloud & jellyfin instances. For this purpose I am using a mini PC. (similiar to an Intel NUC)
Now I would like to make both services available to the internet so I could show images to friends while I’m at their place / watch movies with them.
The problem is I am currently not very educated on which security measures I would have to take to ensure that my server / mini PC doesn’t immediately become an easy target for a hacker, especially considering that I would host private photos on the nextcloud.
After googling around I feel like I find a lot of conflicting information as well as write-ups that I don’t fully grasp with my limited knowledge so if you guys have any general advice or even places to learn about all these concepts I would be absolutely delighted!
Thank you guys sooo much in advance for any and all help, the c/selfhosted community has been nothing but a great resource for me so far!!!

If you are just exposing port 80 and 443 (standard web ports) cloudflare proxy is free and will work well to hide your IP.
Get yourself a domain name then use Cloudflare DNS to set an A record pointing to your home IP. If you have a dynamic IP (one that occasionally changes) you’ll want to read this: https://developers.cloudflare.com/dns/manage-dns-records/how-to/managing-dynamic-ip-addresses/
