Risk3 Technical Surveillance Countermeasures Survey is a Local Technical Inspection of you business environment and assets

• We locate illicit listening devices placed to capture confidential, strategic or other business secrets.

• We work with clients and develop effective counter surveillance strategies.

• We identify those areas most vulnerable to espionage attack.

• We review any existing security policies and arrangements, to determine the level of threat from electronic surveillance.

• We assign a threat level to each location and devise a program to protect that area or asset.

A professional Technical Surveillance Countermeasures Survey should include at least the following:

Spectrum Analysis

A complete analysis of the radio frequency spectrum between 10kHz - 21Ghz, we offer various options depending on the threat level and are capable of performing a spectrum analysis above and beyond 40 GHz (40,000 MHz). A check for all types of transmitters and electro-magnetic radiating devices which transmit audio, video, or data signals, including free space transmissions and devices that utilize the power lines as a transmission media (carrier-current). Special techniques such as sub-carrier, spread spectrum and frequency hopping are also addressed during the RF spectrum analyses. If your current service provider can not cover to at least 18 GHz then they CANNOT BE SURE if there is a device present and they CANNOT protect, you or your business. Be particular wary of unqualified service providers whom can not confirm the presence of signals above 5 GHz.

We utilize various instruments such as computer-controlled spectrum analyzer, spectral correlator, wide band receivers and etc., to detect, demodulate and identify all radio frequency (RF) signals in the area under survey. A spectrum analyzer allows the operator not just to hear but also to see the signals detected. This is helpful in those instances where it is difficult to demodulate signals. The detected signals are also stored on the computer's hard drive for future surveys and comparisons.

Conducting a RF sweep without a spectrum analyzer can be compared to trying to run a computer without a monitor.

Telecommunications Systems Analysis

We are capable of testing digital, electronic and electro-mechanical single and multi-line telephone sets and lines for devices and modifications which would allow the interception of room audio and telephone conversation.

Tests include the use of Single and Multi-line Telephone Analyses designed to detect all known hook switch bypasses, including single and multi-tone, voltage driven and reverse polarity active bypasses.

We also test telephone lines and cable pairs for all known wiretapping techniques or cable pair modifications that would allow for the interception of telephone conversations and room audio. Tests are done to reveal all wire irregularities, including parallel bridge taps and split/re-split inductive wiretaps.

Telephone frame rooms and distribution panels in the area of concern are physically and electronically inspected. The equipment used is compatible with all three generations of telephones, electro-mechanical, electronic and digital systems.

We utilize a single line telephone analyzer and the most advanced computer driven multi-line telephone line analyzer with an oscilloscope, multi-meters, line tracers, etc. The multi-line telephone line analyzer can check up to 16 lines simultaneously. The software functions of the TLA allow the automatic generation of comprehensive test reports.

Physical Inspection

A detailed physical inspection is performed in all areas under investigation. The search includes all drop or feature ceilings, floor coverings, furniture, electronic appliances, and other general office equipment. Particular attention is paid to acoustic leakage to adjoining areas and rooms

The wiring exiting the areas under survey is visually inspected and electronically tested to verify that no room audio is present on the wires. Room surfaces are also examined with Non-Linear Junction Detectors (NLJD's). The NLJD is a microwave device that detects active or passive electronic circuitry that may be hidden in furniture, walls, ceilings, etc.

Risk3 are able to detect inert or dormant, as well as active surveillance devices. New developments are continually reviewed to maintain our superior detection capacity.
