Technical Surveillance Countermeasures


What it is

As the value of information goes up, so does the risk of electronic eavesdropping, wiretapping, computer tampering, or even third-party video surveillance. Today, it is common practice for a business to perform a Technical Surveillance Countermeasure (TSCM). This is a thorough inspection conducted by professionals with the goal of finding and eliminating access points that could be used by a third party to intercept information.

How it works

The inspection typically includes:

  • A complete physical search
  • Radio frequency spectrum analysis to detect transmitters
  • Inspection of metallic cables for faults or anomalies using specialized equipment
  • Analysis of telephone sets and cabling for conductive, resistive, capacitive, or hookswitch bypass techniques
  • Analysis of electric circuits for carrier current transmitters
  • Other specialized detection techniques as circumstances dictate

At the end of the TSCM we will provide a detailed report that includes a description of the scope of work; specific findings for each analysis, test, and inspection; and recommendations for improving or correcting deficiencies.
