[4 minuty čtení] CrowdSec je bezpečnostní nástroj, jehož cílem je chránit služby a servery vystavené do internetu. Inspiroval se klasickým nástrojem Fail2ban, ale jednotlivé instance propojil a sází na sílu davu. Nástroj Fail2ban je tu s námi už téměř dvě dekády a jeho funkce je jednoduchá: démon sleduje vybrané logy a pokud se v nich objeví příliš mnoho neúspěšných pokusů o přihlášení, zablokuje dané IP adrese přístup pomocí systémového firewallu. Útočník tak z dané adresy už nemá šanci zkoušet například hádat hesla.
