Fail2ban Sucks
sounds fun; i see the arch aur has a few options as well. have you tried https://www.cipherdyne.org/fwknop/ ?
-
Has anyone ever had their homelab or network hacked? What happened?
Yes that's the basic idea, i tried to use fwknop first but it didn't do what i wanted it to do so i made my own

How to securely enable SSH access to my home network?
Port knocking. Or better yet FWKNOP. I'm disappointed I don't hear people talk about it more. The port isn't even open until you give the secret combination of knocks on a large number of ports. There's much more to it. I recommend listening to Episode 865 ofSecurity Now.

Show HN: Knockles – eBPF Port Knocking Tool
> Is this approach used elsewhere?
Yes, or at least in a similar fashion. An alternative variant of port knocking is SPA (Single Packet Authorization). Often SPA protocols use UDP and contain within the body field an encrypted payload containing all the required data to authenticate and authorize a particular request.
There are multiple different implementations of SPA: OpenSPA [1] (full disclosure: I am the author of OpenSPA), fwknop [2] just to name a few.
SDP (Software Defined Perimeter) often builds upon SPA technologies in order to achieve a form of zero trust access.

I am currently re-writting the OpenSPA protocol (version 2) and I plan on playing around with eBPF as well, so thanks eeriedusk for paving the way :)

Who's Attacking My Server?
An upgrade to port knocking is Single Packet Authorization [1]. It doesn’t suffer from the observability, and other, problems of port knocking.

How Self Hosting (and password reuse) led to the compromise of Linked In, Dropbox, & more.
Or keep the port closed like I do with my ssh port and use fwknop to open the port only when needed.

What service can I use to ban users?
You should check out https://crowdsec.net. More advanced, uses crowdsources cti to block attacks even before they happen. Also both nginx and captcha is supported. Disclaimer: I am head of community. Visit /r/CrowdSec or our Discord at https://discord.gg/crowdsec if you have questions :-)

Hardening exposed WireGuard ports
Do I need something like crowdsec, or is WireGuard secure enough on its own?

A 'leech-like' connection constantly established on my server
Before falling too much in love with Fail2Ban try taking a look at https://crowdsec.net. Similar functionality but way more advanced (but easier to configure). New project that leverages the power of the crowd and shares information of attacks among users so they help each other out protecting themselves.
What are some alternatives?
pfSense - Main repository for pfSense
Fail2Ban - Daemon to ban hosts that cause multiple authentication errors
Wazuh - Wazuh - The Open Source Security Platform. Unified XDR and SIEM protection for endpoints and cloud workloads.
OSQuery - SQL powered operating system instrumentation, monitoring, and analytics.
autoVPN - Create On Demand Disposable OpenVPN Endpoints on AWS.
ModSecurity - ModSecurity is an open source, cross platform web application firewall (WAF) engine for Apache, IIS and Nginx that is developed by Trustwave's SpiderLabs. It has a robust event-based programming language which provides protection from a range of attacks against web applications and allows for HTTP traffic monitoring, logging and real-time analysis. With over 10,000 deployments world-wide, ModSecurity is the most widely deployed WAF in existence.
Glastopf - Web Application Honeypot
Suricata - Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine developed by the OISF and the Suricata community.
trasa - Zero Trust Service Access
Nginx Proxy Manager - Docker container for managing Nginx proxy hosts with a simple, powerful interface
