Technical Surveillance Counter-Measures (TSCM) Defense & Protocols

Systematic frameworks, physical sweep inspection standards, acoustic speech isolation, and electromagnetic shielding protocols designed to protect critical assets and confidential discussions.

Procedural Standard

Executive Room Inspection Protocol

End-to-end operational sweep methodology for boardrooms, sensitive meeting areas, and C-suite suites prior to critical negotiations.

  • Methodology: Systematic RF, Hardwire, Thermal, and Optical audit
  • Deployment Target: Corporate boardrooms, executive suites, hotels
  • Standard: Full visual, non-linear junction, and spectral deconfliction

Acoustic Hardening

Acoustic Leakage & Speech Protection

Preventing direct audio eavesdropping and laser microphone extraction through window transducers, HVAC masking, and white-noise generators.

  • Countermeasure: Vibroacoustic transducers & omnidirectional masking
  • Target Vectors: Window glass, HVAC ducts, thin partition walls
  • Key Metric: Speech Intelligibility Index (STI) degradation

Optical Defense

Optical & Infrared Sweeping Protocols

Methodologies for detecting pinhole lenses, covert fiber-optic channels, and free-space infrared audio transmitters behind semi-transparent fixtures.

  • Target Profile: Pinhole camera apertures, hidden optics, IR diodes
  • Inspection Mode: Coaxial optical retroreflection and thermal analysis
  • Physical Defense: IR-blocking window films and baffle designs

Electromagnetic Isolation

RF Shielding & Faraday Containment

Engineering architectural barriers to block incoming and outgoing RF signals, preventing wireless eavesdropping and unauthorized exfiltration.

  • Materials: Copper mesh, conductive fabrics, metallized glass coatings
  • Attenuation: >60 dB to 100 dB across 10 MHz – 18 GHz
  • Implementation: Secure SCIFs, shielded enclosures, executive conference pods

Physical Hardline

Physical Infrastructure & Cable Audits

Systematic inspection standards for telecommunications wiring, structured Ethernet, HVAC cavities, and high-voltage power distributions.

  • Audit Tools: TDR analyzers, high-voltage isolators, borescope optics
  • Inspection Target: Cable trays, raised floors, ceiling plenums, phone blocks
  • Defense: Sealed conduit systems and end-to-end loop impedance monitoring

Continuous Monitoring

Permanent In-Place Monitoring Systems (IPMS)

Autonomous 24/7 RF spectrum and signal monitoring arrays deployed inside critical rooms to detect unauthorized burst transmitters in real time.

  • Monitoring Scope: 24/7 RF baseline tracking and burst anomaly alerts
  • Target Vector: Micro-burst recorders, cellular devices brought into meetings
  • Integration: SIEM integration and automated perimeter RF logging
