Technical Surveillance Countermeasures | TSCM
What is Technical Surveillance Countermeasures
Technical Surveillance Countermeasures (TSCM) is a specialized examination that detects, locates and neutralizes bugging devices and identifies technical security vulnerabilities. The ultimate goal of Technical Surveillance Countermeasures is to defend and protect valuable, sensitive, trade secret and private information from illicit access. This is accomplished through a methodical, technical process by a skilled TSCM practitioner using specialized equipment.
A TSCM examination involves detecting and identifying signals emitted by active devices, detecting passive devices as well as identifying surreptitious networks and access points. A through technical surveillance countermeasures exam also includes identifying illicit IMSI catchers that are in use in the survey area. Authorized electronic devices, networks, access points and cellular towers are distinguished from their potentially surreptitious counterparts. Then, surreptitious devices, networks and access points are located and neutralized.
Physical, electronic and network inspections are all integral parts of professional Technical Surveillance Countermeasures. As well, the process includes identifying vulnerabilities that could cause or contribute to illicit electronic access to information. Ultimately, technical surveillance countermeasures must provide actionable intelligence to correct existing exposures. And, it should also identify preventive measures that can reduce the risk of future exposure.
Inspections & Examinations
Technical Surveillance Countermeasures examinations include a physical inspection, electronic inspection and network examination.
The physical inspection includes a visual inspection for the presence of bugs, or indications of tampering. Indications of tampering may include: dust, moved ceiling tiles, newly patched or painted surfaces, damaged or modified walls, misaligned electrical outlets, additional cables or cabling, etc.
The electronic TSCM inspection includes: radio frequency (RF) examination, hidden camera detection, detection of surreptitious networks and access points, detection of Wi-Fi, bluetooth and cellular devices, identification of illicit IMSI catchers, etc. We detect both active and passive electronics during the technical surveillance countermeasures inspection. This ensures bugs that may not be operating during the TSCM inspection, such as store and forward bugs, are also detected.
The network technical surveillance countermeasures inspection includes WiFi, Bluetooth and cellular networks, IoT devices, illicit IMSI catchers, etc. And, detection of personal electronics that are not designed or intended for surreptitious purposes, such as AirPods and AirTags which can used for surreptitious purposes, are also included.
Detection of spyware/malware programs in cell phones, laptops and computers is also important, since the camera and/or microphone of infected devices can be used for illicit purposes. And, GPS trackers, electronic eavesdropping devices and personal electronics (e.g. AirTags, AirPods, etc.) in/on vehicles must also be included since they are also used for illicit monitoring purposes.
