An organisation's most sensitive decisions are made in meetings, often in a handful of rooms. Protecting those conversations from unauthorised listening is the purpose of technical surveillance countermeasures (TSCM), a specialised discipline carried out by trained professionals.
What it addresses
TSCM is concerned with ensuring that sensitive spaces are free of unauthorised surveillance devices and that the environment around them does not leak information. It is a protective measure for the organisation, focused on keeping private discussions private.
When organisations consider it
- Around sensitive negotiations, decisions or announcements
- After moving premises or completing building works
- As part of a regular programme for sensitive facilities
- When there is reason to suspect a compromise
Part of a wider approach
TSCM is most effective alongside access control to sensitive areas, secure communications and staff awareness. Services and any related equipment are provided to authorised organisations under the applicable authorisations, and discussed confidentially.
Capabilities are shared confidentially, with authorised organisations only.
