Failban

Noun · Security & Infosec

Definitions

  1. Shorthand for automated banning based on repeated failed actions, often associated with tools like Fail2ban that watch logs and temporarily block abusive IPs. It is commonly used to slow password guessing and noisy scanning against services such as SSH.

    In plain English: Automatically blocking a source after too many failed or suspicious attempts.

    Example: "We put failban on the exposed SSH host so repeated bad logins triggered an automatic block."
