TSCM- Protection from eavesdropping
Active inspection - non alerting
- Minor Noise is created, however, it should not alert the eavesdropping
- VLF/RF check- AC mains (all electrical outlets)
- VLF/RF check- AC mains (all light switches/fixtures)
- VLF/RF check- HVAC controls
- VLF/RF check- Alarm and access control sensors
- VLF/RF check- Fire and safety sensors/alarms
- VLF/RF check- Other
- All phone lines evaluated and traced back to central office
- All artifacts documented, recorded and inspected
- Oblique lighting inspection of all walls and artifact
- Initial inspection of base boards, windows frames and door jambs
- Initial inspection of all wall plate
- UV lighting sweep (below 400nm)
- IR lighting sweep (above 700nm)
- Visible spectrum light sweep (350nm to 750nm)
- Tuned forensic light source and filter sweep (250nm to 1750nm)
- Check for telephone set problems and phone tap
- Check for software and hardware anomalies
- Check for voice mail modifications
- Inspetion of all computer and LAN connections
- Inspection of all laser printers and computer output devices
- Law enforcement and professional bugs will be detected during this phase
- Typical threat level for most corporate offices
Active scan - alerting
- Chirp detection of hidden mircophones and other transducers
- IR, audio and ultrasonic wave jamming (as required)
- Render the eavesdropping device temporarily inoperative

- Inventory of all conductors, conduits, wall studs etc.
- Detailed electromagnetic energy search
- Professional eavesdropping devices will be detected during this phase
Active scan - alerting/evalution
- Verify and TDR/FEXT/NEXT trace all conductors
