A correct statement about technical security countermeasures (TSCM) is that they:

Technical Security Countermeasures (TSCM) are a critical, specialized component within a comprehensive security program. They are not a standalone solution but are integrated into an organization's overall protection strategy to mitigate the specific risk of electronic eavesdropping and technical surveillance. A successful information protection program relies on a layered approach, combining physical, personnel, procedural, and technical controls. TSCM addresses the technical surveillance threat vector as part of this holistic framework, complementing other security measures designed to protect sensitive information and assets.

A. TSCM requires highly specialized training, sophisticated equipment, and expertise in electronics and radio frequency theory, which is beyond the qualifications of an average security supervisor.

B. While government entities have their own TSCM programs and standards, private sector TSCM services do not generally require specific government approval to operate, though licensing may apply.

D. The core function of a TSCM survey involves a meticulous on-site physical and electronic examination of a space; it cannot be conducted effectively from a remote location.

"General

" states

"The TSCM program should be an integral part of the organization’s overall security program and risk management process." This directly supports the correct answer (C). Section 5

"TSCM Personnel

" details the extensive knowledge and skills required

refuting option A. Section 6

"TSCM Operations

" describes the on-site process

refuting option D.

Chapter 3

"Protecting Sensitive Information

" discusses TSCM as one of several countermeasures within a broader program designed to protect proprietary and sensitive information

reinforcing that it is part of an overall strategy.

T. J. (2010). Building a Corporate TSCM Program. Security Management. ASIS International. This publication emphasizes that "a TSCM program must be part of a larger security effort that includes information

physical

and personnel security... Without the support of these other disciplines

a TSCM program will fail." This highlights the integrated nature of TSCM.
