Hey guys,

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!!!
