TSCM | Technical Surveillance Countermeasures Services | Telecommunications and Technical Security Consultation

The technical portion of the technical surveillance countermeasures (TSCM) survey consists of the following procedures:

Radio Frequency (RF) Detection:

Thorough RF analysis requires a variety of instruments. Our RF detection equipment includes two spectrum analyzers, an Omni Spectral Correlator (OSCOR), three communications receivers, three carrier current receivers, a digital and burst transmitter detector, and two near field transmitter detectors. Infrared transmitter detection falls under RF detection, and we use an Electrophysics infrared light viewer for that purpose.

RF analysis in commercial environments includes looking for rouge wireless access points attached to the company’s LAN or WAN. An ultra-mobile computer equipped with wireless network analysis software is used for this purpose. We also look for open Bluetooth™ devices.

Telephone Tap and Eavesdropping Modification Detection:

Telephone system inspections involve several pieces of test equipment. Instruments such as a Time Domain Reflectometer (TDR), digital oscilloscope, audio amplifiers, digital and analog telephone analyzers, fluoroscope (X-Ray), wire tracing equipment, and special telecommunications tools are used to inspect for eavesdropping devices.

Physical Search and Miscellaneous Equipment:

The physical search is augmented by the use of sophisticated instruments and equipment. Our nonlinear junction detector, for example, is engineered to detect components used in eavesdropping devices. If a device is not operating because the batteries have gone dead, the nonlinear junction detector will detect it because of its components. The use of a thermal imaging camera helps us to see minute temperature variations that might indicate the presence of a surveillance device. If an eavesdropper turned off his transmitter before the investigators entered the building, the heat caused by the power flowing through the device would be visible when using the thermal imaging camera.

The physical search can include the use of a metal detector, densimeter, x-ray, ultraviolet inspection lamp, camera lens detector, and a variety of hand tools.

Benefits of Regular TSCM Inspections

	Locate, identify and neutralize clandestine surveillance devices.
	Locate, identify and recommend corrections to office equipment which can be exploited for espionage purposes.
	Helps satisfy the obligation to protect confidential information as described in the Economic Espionage Act of 1996.
	Deterrent to future espionage attempts.
	Shareholders and employees appreciate management’s serious approach to protecting proprietary data or information critical to national security.
	Peace of mind that you have taken positive steps toward maintaining your competitive edge.
	Serves as an independent security audit.
