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
  • Inspection of all furnishings (desks, chairs, plants etc)
  • Open ceilings and walls (move ceiling tiles and panels)
  • Thermal inspection
  • HVAC and duct work inspection
  • Acoustical leakage inspection
  • Borescope inspection of all electrical wall plates and boxes
  • Detailed inspection of all lighting fixtures
  • 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
  • TDR trace- Telephone system wiring
  • TDR trace- Computer network wiring
  • TDR trace- Cable television and CCTV
  • TDR trace- AC mains, all electrical wiring
  • TDR trace- AC mains, all light switches
  • TDR trace- HVAC controls
  • TDR trace- Alarm and access control senors
  • TDR trace- Fire and safety alarms
  • Other TDR trace
  • Voice mail system evaluation
  • Xerox machine inspection
  • Fax machine inspection
  • Wall, floor and ceiling cavity inspection
  • Intense physical inspection (every cubic centimeter)

Special inspecition activities

  • Non-linear junction detector inspection ( NLJD) - active and passive
  • X-ray, radiographic inspection
  • Magnetic anomaly inspection
