The organization requires users to reauthenticate upon organization-defined circumstances or situations requiring reauthentication.

Enforce organization-defined circumstances and/or usage conditions for organization-defined system accounts.

Automatically lock the account or node for either an organization-defined time period, until the locked account or node is released by an administrator, or delays the next logon prompt according to the organization-defined delay algorithm when the maximum number of unsuccessful logon attempts is exceeded.

Only allow the use of organization-defined certificate authorities for verification of the establishment of protected sessions.

Disable accounts when the accounts have expired.

Disable accounts when the accounts are no longer associated to a user.

Disable accounts when the accounts are in violation of organizational policy.

Implement organization-defined mechanisms to authenticate organization-defined remote commands.

Require users to be individually authenticated before granting access to the shared accounts or resources.

For password-based authentication, update the list of passwords on an organization-defined frequency.

For password-based authentication, update the list of passwords when organizational passwords are suspected to have been compromised directly or indirectly.

For password-based authentication, 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).

For password-based authentication, store passwords using an approved salted key derivation function, preferably using a keyed hash.

For password-based authentication, require immediate selection of a new password upon account recovery.
