Title

The operating system must for password-based authentication, require immediate selection of a new password upon account recovery. (Cat II impact)

Discussion

Password-based authentication applies to passwords regardless of whether they are used in single-factor or multifactor authentication. Long passwords or passphrases are preferable over shorter passwords. Enforced composition rules provide marginal security benefits while decreasing usability. However, organizations may choose to establish certain rules for password generation (e.g., minimum character length for long passwords) under certain circumstances and can enforce this requirement in IA-5(1)(h). Account recovery can occur, for example, in situations when a password is forgotten. Cryptographically protected passwords include salted one-way cryptographic hashes of passwords. The list of commonly used, compromised, or expected passwords includes passwords obtained from previous breach corpuses, dictionary words, and repetitive or sequential characters. The list includes context-specific words, such as the name of the service, username, and derivatives thereof.

Check Content

Verify the operating system is configured to require immediate selection of a new password upon account recovery for password-based authentication. If the operating system is not configured to require immediate selection of a new password upon account recovery for password-based authentication, this is a finding.

Fix Text

Configure the operating system to require immediate selection of a new password upon account recovery for password-based authentication.
