System updates over tor connecting to onion repos.
How does this help, assuming your DNS isn’t being spoofed?

Only remote access by wireguard and ssh on non standard port with key based access.
Fail2ban bans after 1 attempt for a year Logs are encrypted and mailed off site daily
System updates over tor connecting to onion repos.
Nginx only has one exposed port 443 that is accessible by wireguard or land. Certs are signed by letsencrypt. Paths are ip white listed to various lan or wireguard ips.
I dont allow devices I dont admin on the network so they go on their own subnet. This is guests phones and their windows laptops.
Linux only on the main network.
I also make sure to backup often.

Thanks, never thought of that before. I’ll certainly try it, great way to help the network!

Is that a security benefit?

If big corporations hoovering your data should be on everyone’s threat list, then yea, i’d say its a huge benefit.
JoeKrogan@lemmy.world 7 months ago
Well I dont trust closed source software and so what I can to avoid it when I can. At least foss can be audited. Also all the linux devices on the main network are devices I admin.

I guess it cuts the attack surface profile down a bit?

Fail2ban bans after 1 attempt for a year.
Fail2ban yes; one year, however, is IMO a bit excessive.
Most ISP IP assignments do tend to linger - even with DHCP the same IP will be re-assigned to the same gateway router for quite a number of sequential times - but most IPs do eventually change within a few months. I personally use 3 months as a happy medium for any blacklist I run. Most dynamic IPs don’t last this long, almost all attackers will rotate through IPs pretty quickly anyhow, and if you run a public service (website, etc.), blocking for an entire year may inadvertently catch legitimate visitors.
Plus, you also have to consider the load such a large blocklist will have on your system, if most entries no longer represent legitimate threat actors, you’ll only bog down your system by keeping them in there.
Fail2ban can be configured to allow initial issues to cycle back out quicker, while blocking known repeat offenders for a much longer time period. This is useful in keeping block lists shorter and less resource-intensive to parse.

My block list is very small actually due to the non standard ssh port. Everything else goes through wireguard.
If it was open to the public then yes I’d have to reconsider the ban length.

That makes a lot more sense for your setup, then.

Can you explain why you use onion repos? I’ve never heard of that, and I’ve heard of kind of a lot of things.
JoeKrogan@lemmy.world 7 months ago
Onion repositories are package repositories hosted on tor hidden services. The connection goes through six hops and is end to end encrypted. In addition to further legitimizing the tor network with normal everyday usage it has the benefit of hiding what packages have been installed on a system.
Whonix has some notes about it here if you want to read more.

That’s pretty neat. I might start doing that, just for kicks.

That is very interesting, thanks!

With Debian it’s just the apt-tor package, and the project maintains an official list at… onion.Debian.org iirc?
I don’t know if serving onion traffic is more expensive for Debian/mirror maintainers so idk if this is something everybody should use
