Not Using Password Aging

If no mechanism is in place for managing password aging, users will have no incentive to update passwords in a timely manner.


Description

Security experts have often recommended that users change their passwords regularly and avoid reusing passwords. Although this can be an effective mitigation, if the expiration window is too short, it can cause users to generate poor or predictable passwords. As such, it is important to discourage creating similar passwords. It is also useful to have a password aging mechanism that notifies users when passwords are considered old and requests that they replace them with new, strong passwords. Companion documentation which stresses how important this practice is can help users understand and better support this approach.

Demonstrations

The following examples help to illustrate the nature of this weakness and describe methods or techniques which can be used to mitigate the risk.

Note that the examples here are by no means exhaustive and any given weakness may have many subtle varieties, each of which may require different detection methods or runtime controls.

Example One

A system does not enforce the changing of passwords every certain period.
