3.5.7[a]

  • Determination Statement

    Password complexity requirements are defined.

  • Requirement

    Enforce a minimum password complexity and change of characters when new passwords are created.

  • Requirement Discussion

    This requirement applies to single-factor authentication of individuals using passwords as individual or group authenticators, and in a similar manner, when passwords are used as part of multifactor authenticators. The number of changed characters refers to the number of changes required with respect to the total number of positions in the current password. To mitigate certain brute force attacks against passwords, organizations may also consider salting passwords.
