Information Assurance - Unauthorized Wireless Devices - Portable Electronic Devices (PEDs) Used in Classified Processing Areas without Certified TEMPEST Technical Authority (CTTA) Review and Authorizing Official (AO) Approval.

Allowing wireless devices in the vicinity of classified processing or discussion could directly result in the loss or compromise of classified or sensitive information either intentionally or accidentally.

1. Check to ensure that unauthorized wireless devices (PEDs such as cellphones, BlackBerry devices, laptops, etc.) are not being used in areas where classified systems or machines (SIPRNet) are in use. 2. If PED usage in classified processing areas is permitted by the site, check to ensure there is specific written AO (formerly DAA) approval and that a CTTA has assessed the environment and that any resulting recommended TEMPEST countermeasures have been implemented. TACTICAL ENVIRONMENT: The check is applicable for ALL classified processing environments.

1. Unauthorized wireless devices (PEDs such as cellphones, BlackBerry devices, laptops, etc.) must not be permitted for use in areas where classified systems or machines (SIPRNet) are in use. 2. If PED usage in classified processing areas is permitted, there must be specific written AO (formerly DAA) approval and a CTTA assessment of the environment and any resulting recommended TEMPEST countermeasures must be implemented.
