Byeman Control System

The BYEMAN Control System (BCS), or simply BYEMAN (designated BYE, or B), was a security control system put in place to protect information about the National Reconnaissance Office (NRO) and its operations.

History

The BYEMAN Control System was put in place in 1961 by the Central Intelligence Agency (CIA).

Discussions regarding BCS retirement were held as early as 2003. DNRO Peter B. Teets spoke at a 2003 NRO Town Hall meeting, mentioning that retiring the BCS would remove barriers that prevented the NRO and U.S. Intelligence Community from working together as a team.

The use of BCS was so prevalent throughout the U.S. Intelligence Community, that a handful of websites were set up to direct users through the retirement process.

Origin of Name

An individual inside the CIA's Special Security Center chose the name from a random list of four words drawn from the CIA's codeword file. A byeman is a man who works underground; it is unknown if the individual knew the word's meaning before its selection.

Control system

A control system is a device, or set of devices, that manages, commands, directs or regulates the behaviour of other devices or systems. Industrial control systems are used in industrial production for controlling equipment or machines.

There are two common classes of control systems, open loop control systems and closed loop control systems. In open loop control systems output is generated based on inputs. In closed loop control systems current output is taken into consideration and corrections are made based on feedback. A closed loop system is also called a feedback control system.

Overview

The term "control system" may be applied to the essentially manual controls that allow an operator, for example, to close and open a hydraulic press, perhaps including logic so that it cannot be moved unless safety guards are in place.

An automatic sequential control system may trigger a series of mechanical actuators in the correct sequence to perform a task. For example various electric and pneumatic transducers may fold and glue a cardboard box, fill it with product and then seal it in an automatic packaging machine. Programmable logic controllers are used in many cases such as this, but several alternative technologies exist.
