Abstract

EnFilter is a Proactive Password Checking System, designed to avoid password guessing attacks. It is made of a set of configurable filters, each one based on a specific pattern recognition measure that can be tuned by the system administrator depending on the adopted password policy. Filters use decision trees, lexical analysers, as well as Levenshtein distance based techniques. EnFilter is implemented for Windows 2000/2003/XP.
