So DNS Black-holing is not new obviously, and what stands out as the go to solution? Pihole probably... and yeah thats what im using because hey its a popular choice. Though I am running it in docker. Combining that with Unbound (also in docker), and configuring outbound DNS to use DNS over TLS, with a few additional minor tweaks, but otherwise mostly standard configuration on both.
Wondering what you guys might be using, and if you are using Pihole and/or Unbound if you have any tips on configuration.
Happy to share my config if there is interest.
"Dnsbl is only a small component of effective network security. Arguably the firewall is most important and so I have a default deny all for any device on my LAN trying to reach the Internet." 100%, I decided to break up my posts into sub components of the total stack, but to your point currently im enforcing a deny all inbound and outbound at the host level, as the network is shared with the fam and they are not ready for that level of learning (pain, lol)
I just learned about unbound, didnt realize it had a blocklist capability so thats great to know. Gotta dig into it.
I like that last bit, blocking DoT except for the one approved path. Much like TLS 1.3 it offers insider threat protection against inspection. So with that in mind when you said you are using unbound instead of using DoT forwarding, you mean instead of allowing clients to DoT forward, right? Thats what I am doing now as well, though I am not actively blocking it yet. Just currently enabling and testing feasibility on a single host to see the performance and operational impacts of privacy/security implementations.
Curious to your IDS solution, I gotta dig into opnsense. I know about it, its been around a long time, but havent touched it in so long I cant remember its capabilities.
