What type of pager is permitted in SAP areas?

• A. Two-way pagers
• B. Receive-only pagers
• C. Smart pagers
• D. Digital pagers

Answer: (B)

In SAP areas, receive-only pagers are permitted because they are designed to only receive messages and cannot transmit or send information back. This limitation is crucial in maintaining the security and integrity of sensitive information in Controlled Unclassified Information (CUI) fields, as they do not have the capability to interact with networked environments or potentially compromise the security of the systems in place.

Receive-only functionality minimizes the risk of unauthorized communication or data breaches, as these devices cannot inadvertently allow sensitive data to be sent out of the SAP area. This makes them a more secure option compared to two-way pagers and smart pagers, which have transmission capabilities and could introduce vulnerabilities.

Digital pagers may function similarly to receive-only ones, but the nuanced capability of transmitting over networks makes them less secure than strictly receive-only devices. Thus, the specific permission for receive-only pagers is to ensure compliance with security measures in sensitive environments.
