In this proceeding, the Commission proposes prohibiting the authorization of any communications equipment on the list of equipment and services  (Covered List) that the Commission maintains pursuant to the Secure and Trusted Communications Networks Act of 2019.  Such equipment has been found to pose an unacceptable risk to the national security of the United States or the security and safety of United States persons.  We also seek comment on whether and under what circumstances we should revoke any existing authorizations of such covered communications equipment.  We invite comment on whether we should require additional certifications relating to national security from applicants who wish to participate in Commission auctions.  In the Notice of Inquiry, we seek comment on other actions the Commission should consider taking to create incentives in its equipment authorization processes for improved trust through the adoption of cybersecurity best practices in consumer devices.
