crowdsec v1.3.4 releases: open-source and lightweight software
About the crowdsec project
Crowdsec is open-source and lightweight software that allows you to detect peers with malevolent behaviors and block them from accessing your systems at various levels (infrastructural, system, applicative).
To achieve this, Crowdsec reads logs from different sources (files, streams …) to parse, normalize and enrich them before matching them to threats patterns aka scenarios.
It is a modular and plug-able framework, it ships a large variety of well-known popular scenarios; users can choose what scenarios they want to be protected from as well as easily add new custom ones to better fit their environment.
Detected malevolent peers can then be prevented from accessing your resources by deploying blockers at various levels (applicative, system, infrastructural) of your stack.
One of the advantages of Crowdsec, when compared to other solutions, is its crowded aspect: Meta information about detected attacks (source IP, time, and triggered scenario) are sent to a central API and then shared amongst all users.
Besides detecting and stopping attacks in real-time based on your logs, it allows you to preemptively block known bad actors from accessing your information system.
Key points
Fast assisted installation, no technical barrier
User is assisted during setup, providing functional out-of-the-box setup
Out of the box detection
Baseline detection is effective out-of-the-box, no fine-tuning required 
Easy blocker deployment
It’s trivial to add blockers to enforce decisions of crowdsec 
Easy dashboard access
It’s easy to deploy a Metabase interface to view your data simply with cscli
This repository contains the code for the two main components of crowdsec :
- crowdsec : the daemon a-la-fail2ban that can read, parse, enrich, and apply heuristics to logs. This is the component in charge of “detecting” the attacks
- cscli: the cli tool mainly used to interact with crowdsec: ban/unban/view current bans, enable/disable parsers, and scenarios.
