How to set up a CrowdSec multi-server installation
Learn how to set up a CrowdSec multi-server installation to secure Internet-exposed Linux services, servers, containers, or virtual machines in this tutorial.
CrowdSec is an open-source & collaborative security solution built to secure Internet-exposed Linux services, servers, containers, or virtual machines with a server-side agent. It is a modernized version of Fail2ban which was a great source of inspiration to the project founders.
CrowdSec is free (under an MIT License) and its source code available on GitHub. The solution is leveraging a log-based IP behavior analysis engine to detect attacks. When the CrowdSec agent detects any aggression, it offers different types of remediation to deal with the IP behind it (access prohibition, captcha, 2FA authentication etc.). The report is curated by the platform and, if legitimate, shared across the CrowdSec community so users can also protect their assets from this IP address.
