The following 21 compliance controls are associated with this Policy definition 'Manage Authenticators' (4aacaec9-0628-272c-3e83-0d68446694e0)
The organization manages information system authenticators by:
a. Verifying, as part of the initial authenticator distribution, the identity of the individual, group, role, or device receiving the authenticator;
b. Establishing initial authenticator content for authenticators defined by the organization;
c. Ensuring that authenticators have sufficient strength of mechanism for their intended use;
d. Establishing and implementing administrative procedures for initial authenticator distribution, for lost/compromised or damaged authenticators, and for revoking authenticators;
e. Changing default content of authenticators prior to information system installation;
f. Establishing minimum and maximum lifetime restrictions and reuse conditions for authenticators;
g. Changing/refreshing authenticators [Assignment: organization-defined time period by authenticator type];
h. Protecting authenticator content from unauthorized disclosure and modification;
i. Requiring individuals to take, and having devices implement, specific security safeguards to protect authenticators; and
j. Changing authenticators for group/role accounts when membership to those accounts changes.
Supplemental Guidance: Individual authenticators include, for example, passwords, tokens, biometrics, PKI certificates, and key cards. Initial authenticator content is the actual content (e.g., the initial password) as opposed to requirements about authenticator content (e.g., minimum password length). In many cases, developers ship information system components with factory default authentication credentials to allow for initial installation and configuration. Default authentication credentials are often well known, easily discoverable, and present a significant security risk. The requirement to protect individual authenticators may be implemented via control PL-4 or PS-6 for authenticators in the possession of individuals and by controls AC-3, AC-6, and SC-28 for authenticators stored within organizational information systems (e.g., passwords stored in hashed or encrypted formats, files containing encrypted or hashed passwords accessible with administrator privileges). Information systems support individual authenticator management by organization-defined settings and restrictions for various authenticator characteristics including, for example, minimum password length, password composition, validation time window for time synchronous one-time tokens, and number of allowed rejections during the verification stage of biometric authentication. Specific actions that can be taken to safeguard authenticators include, for example, maintaining possession of individual authenticators, not loaning or sharing individual authenticators with others, and reporting lost, stolen, or compromised authenticators immediately. Authenticator management includes issuing and revoking, when no longer needed, authenticators for temporary access such as that required for remote maintenance. Device authenticators include, for example, certificates and passwords. Related controls: AC-2, AC-3, AC-6, CM-6, IA-2, IA-4, IA-8, PL-4, PS-5, PS-6, SC-12, SC-13, SC-17, SC-28.

The organization maintains a list of commonly-used, expected, or compromised passwords, and updates the list (i) at least every 180 days and (ii) when organizational passwords are suspected to have been compromised (either directly or indirectly); allows users to select long passwords and passphrases, including spaces and all printable characters; employs automated tools to assist the user in selecting strong passwords and authenticators; and verifies, when users create or update passwords, that the passwords are not found on the organization-defined list of commonly-used, expected, or compromised passwords.

User registration and deregistration, at a minimum: (i) communicates relevant policies to users and require acknowledgement (e.g., signed or captured electronically); (ii) checks authorization and minimum level of access necessary prior to granting access; (iii) ensures access is appropriate to the business needs (consistent with sensitivity/risk and does not violate segregation of duties requirements); (iv) addresses termination and transfer; (v) ensures default accounts are removed and/or renamed; (vi) removes or blocks critical access rights of users who have changed roles or jobs; and, (vii) automatically removes or disables inactive accounts.
Authenticate (or verify) the identities of users, processes, or devices, as a prerequisite to allowing access to organizational systems.

Microsoft and the customer share responsibilities for implementing this requirement.
Individual authenticators include the following: passwords, key cards, cryptographic devices, and one-time password devices. Initial authenticator content is the actual content of the authenticator, for example, the initial password. In contrast, the requirements about authenticator content include the minimum password length. Developers ship system components with factory default authentication credentials to allow for initial installation and configuration. Default authentication credentials are often well known, easily discoverable, and present a significant security risk. Systems support authenticator management by organization-defined settings and restrictions for various authenticator characteristics including minimum password length, validation time window for time synchronous one-time tokens, and number of allowed rejections during the verification stage of biometric authentication. Authenticator management includes issuing and revoking, when no longer needed, authenticators for temporary access such as that required for remote maintenance. Device authenticators include certificates and passwords. [SP 800-63-3] provides guidance on digital identities.
