  • Further Discussion

    Ensure all employees who need access to CUI undergo organization-defined screening before being granted access. Base the types of screening on the requirements for a given position and role.

    The effective screening of personnel provided by this requirement, PS.L2-3.9.1, improves upon the effectiveness of authentication performed in IA.L2-3.5.2.


    You are in charge of security at your organization. You complete standard criminal background and credit checks of all individuals you hire before they can access CUI [a]. Your screening program follows appropriate laws, policies, regulations, and criteria for the level of access required for each position.
