CMMC Practice Requirement:
Allow temporary password use for system logons with an immediate change to a permanent password.
CMMC Requirement Explanation:
Temporary passwords often follow a consistent style (e.g. ChangeMe2020!), this means that they can be more easily guessed by an attacker. If users are forced to change their password upon receiving a temporary one you can reduce this risk. For added security you can provide employees with a randomly generated password when they request a reset.
Example CMMC Implementation:
When providing a temporary password to a user set their account to require a password reset upon login. An example of when this will need to be done is when providing a password to a new employee or when an employee requests a password reset.
Scenario(s):
- Scenario 1:
Example:
John has requested a new password. Alice resets his password and sets his account to require a new password upon login. Alice provides John with the password, when John logs in he is required to set a new one.
