Hey all,
Hope this is the right place to be asking (Reddit refugee), but do any of you setup certs for inward facing services? For example, I run “Whoogle” on my proxmox server, which I then access from several other devices when performing searches.
The connection between my machines and that proxmox VM are not encrypted, however only my VLAN (for personal devices) is able to access it.
Is it good practice to create a certificate for those types of servers that can only be accessed within your own network, or overkill?
It is always good practice to set up certificates everywhere. I do it for all of my internal services. Each person has a different level of care for how important privacy and security are and some people have abnormal threat profiles.
With that being said, options are usually to run self signed certificates, roll your own certificate authority for your network, or get valid certificates from a service like letsencrypt.
I point my DNS at local IPs then use Let’s Encrypt with DNS validation.
