Quality of password management policy

The use of passwords is the most common method to carry out the authentication of users in information systems. For this reason, quality in the password management is a need to reach reasonable levels in the typical objectives of security. In this paper, we propose a set of metrics of password policies based on the most outstanding factors in this authentication mechanism. Together with the metrics, we propose a quality indicator derived from these metrics that allows us to have a global vision of the quality of the password management policy used. Finally, we indicate the future works to be performed to check the validity and usefulness of the proposed metrics.
