I self-host a couple of services, but I haven’t exposed anything outside my home network. I want to self-host my calendar, but not sure if I can do it without exposing it. Any recommendations on the best way to go about this? For those who do self-host a calendar service, how do you keep it secure?
You must log in or register to comment.
Radicale is the GOAT and supports authentication. Or you can just run it on a LAN behind a firewall.
VPN is the way to go if you’re not sharing it with a bunch of people
I think the general consensus for homelabbers is a mesh network – Tailscale and Netbird are the two most popular options
Or headscale.
Related question, what CalDAV server are you using? Been looking for something lightweight
I run nextcloud on my machine. If there’s a crack, there would be one in their hosted instance as well. There’s nothing really I can do about security of it.
I do not expose Nextcloud to the internet. I use dnsmasq to give LAN clients the private IP. If I need to access NC from elsewhere, there’s VPN for that.
Sounds like a good solution as well
mTLS with a reverse proxy!
What caldav clients supports that?
I’d recommend the Tailscale style approach. MTLS is a pain imo without infrastructure and especially on the app layers
This is the first time I’ve heard of mTLS. Sounds interesting, any tutorial recs?
Who do you want to have access to said calendar?
Just myself, but I would like to keep it synced between my phone and my laptop while also keeping a backup.
Then you should really look into setting up a personal VPN. After that what you use to do calendar becomes irrelevant in terms of access.
Could you set up a Cloudflare tunnel and make sure the security rules are tight enough to keep others out?
