crowdsec v1.5.4 releases: open-source and lightweight software
About the crowdsec project
Crowdsec is an 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.
Fast assisted installation, no technical barrier
Out of the box detection
Easy blocker deployment
Easy dashboard access
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.
