Personal Network Attached Storage, basic approach questions
I am often seen as "the it desk" for relatives and friends but as an F5 employee I am not even close.
I work with experts who know security, know networking, and grew up with (or invented) tech generally.
I don't have any F5 equipment at home...but this is sorta home-lab-ish for someone who "plays IT Support on TV."
I bit off a lot of tech (at least for me) when I bought a Synology NAS DS720+ to manage my personal machine backups and then also the HUGE amounts of photos my family is producing on their phones. I grow weary of paying [insert service provider here] $XX/month to synch that stuff when I have a perfectly capable 4TB NAS in my home. I'm slowly getting used to how it works (I bought it one year ago) and it's doing the basics but I have a few other basic questions that may help me move forward.
Security - I changed the default Admin password but I can't figure out how to *CONFIRM* that my NAS is not open to the internet. My queries to the excellent Synology KB site (https://kb.synology.com/en-us/DSM) are sorta the OPPOSITE of what a NAS is supposed to be for. Until this point I only want Local Network access secure from anyone scanning the internet and using my NAS for their bot army. My DSM (the OS for Synology NAS) version is 7.0+.
How do I confirm this device isn't connected to the open internet but still handling local traffic?
(I have more next-steps-questions like, What is the basics about then turning around and enabling remote Phone backups? How often do I need to look at this system to deal with security patches (the tension between ease of use and security) but..is it weird to ask this here?
