A TSCM survey will provide a professional evaluation of the facility's technical security posture and normally will consist of a thorough visual, electronic, and physical examination in and about the surveyed facility.

The advent of multimedia devices and remote control technologies allow huge scope for removal of massive amounts of data in very secure environments by the staff employed within, with or without their knowledge.

Technical Surveillance Countermeasures (TSCM) can best be defined as The systematic physical and electronic examination of a designated area by properly trained, qualified and equipped persons in an attempt to discover electronic eavesdropping devices, security hazards or security weaknesses.

The reality:

  • We will be looking for what threats are potentially faced, where they may come from, and how to defend against them.
  • We will be looking at the potential to place a device or listening device in the office. We will look at the "in and out of hours" access to the office and assess the possibilities the access would provide for someone wishing to place a device.
  • We will also be looking at existing background transmissions that could hide or mask a device and make it more difficult to locate and many other important areas that need to be considered. 
  • We will assess the technical surveillance threat levels and, ascertain the products that could be placed and the threat level that exists.
  • We will look at background transmissions and electronic noise floor levels. We will evaluate computer hardware and telephone systems and the potential to place technical and listening devices.
  • We will take readings of the sound transference ability of connecting walls in all sensitive areas and evaluate potential devices based on the design and construction of the office, including some indication of how, where and what devices could be fitted.
