Description
For password-based authentication:
(a) Maintain a list of commonly-used, expected, or compromised passwords and update the list [Assignment: organization-defined frequency] and when organizational passwords are suspected to have been compromised directly or indirectly;
(b) Verify, when users create or update passwords, that the passwords are not found on the list of commonly-used, expected, or compromised passwords in IA-5(1)(a);
(c) Transmit passwords only over cryptographically-protected channels;
(d) Store passwords using an approved salted key derivation function, preferably using a keyed hash;
(e) Require immediate selection of a new password upon account recovery;
(f) Allow user selection of long passwords and passphrases, including spaces and all printable characters;
(g) Employ automated tools to assist the user in selecting strong password authenticators; and
(h) Enforce the following composition and complexity rules: [Assignment: organization-defined composition and complexity rules].
IA-5 (1) Additional FedRAMP Requirements and Guidance:
Guidance: Note that (c) and (d) require the use of cryptography which must be compliant with Federal requirements and utilize FIPS validated or NSA approved cryptography (see SC-13).
Requirement: Password policies must be compliant with NIST SP 800-63B for all memorized, lookup, out-of-band, or One-Time-Passwords (OTP). Password policies shall not enforce special character or minimum password rotation requirements for memorized secrets of users.
(h) Requirement: For cases where technology doesn't allow multi-factor authentication, these rules should be enforced: must have a minimum length of 14 characters and must support all printable ASCII characters.
For emergency use accounts, these rules should be enforced: must have a minimum length of 14 characters, must support all printable ASCII characters, and passwords must be changed if used.
