Detailed Policy Requirements: Note: This requirement does not apply to the SME PED. Note: This requirement does not apply to the SWLAN SecNet 11/54 equipment. The IAO will ensure wireless devices are not operated in areas where classified information is electronically stored, processed, or transmitted unless: - Approved by the DAA in consultation with the Certified TEMPEST Technical Authority (CTTA). - The wireless equipment is separated from the classified data equipment at the minimum distance determined by the CTTA and appropriate countermeasures, as determined by the CTTA, are implemented. Check Procedures: Review documentation. Work with the traditional security reviewer to verify the following: 1. If classified information is not processed at this site, mark as not a finding. 2. If the site has a written procedure prohibiting the use of wireless devices in areas where classified data processing occurs, mark as not a finding. Ask for documentation showing the CTTA was consulted about operation and placement of wireless devices. Acceptable proof would be the signature or initials of the CTTA on the architecture diagram or other evidence of coordination. IAW DoD policy, the CTTA must have a written separation policy for each classified area. 3. Review written policies, training material, or user agreements to see if wireless usage in these areas is addressed. 4. Verify proper procedures for wireless device use in classified areas is addressed in training program. Mark as a finding if any of the following is found: - CTTA has not designated a separation distance in writing. - DAA has not coordinated with the CTTA. - Users are not trained or made aware (using signage or user agreement) of procedures for wireless device usage in and around classified processing areas.
