a. Establish rules that describe the responsibilities and expected behavior for system usage and protecting CUI.

b. Provide rules to individuals who require access to the system.

c. Receive a documented acknowledgement from individuals indicating that they have read, understand, and agree to abide by the rules of behavior before authorizing access to CUI and the system.

d. Review and update the rules of behavior [Assignment: organization-defined frequency].

Discussion:

Rules of behavior represent a type of access agreement for system users. Organizations consider rules of behavior for the handling of CUI based on individual user roles and responsibilities and differentiate between rules that apply to privileged users and rules that apply to general users.

Assessment Methods and Objectives

Examine [SELECT FROM: security planning policy and procedures; rules of behavior for system users; signed acknowledgements of rules of behavior; records for rules of behavior reviews and updates; system security plan; other relevant documents or records]

Interview [SELECT FROM: personnel with rules of behavior establishment, review, and update responsibilities; personnel with literacy training and awareness responsibilities; personnel with role-based training responsibilities; authorized users of the system who have signed rules of behavior; personnel with information security responsibilities]

Test [SELECT FROM: processes for establishing, reviewing, disseminating, and updating rules of behavior; mechanisms for supporting or implementing the establishment, dissemination, review, and update of rules of behavior]
