Before an effective defence can be put in place you must identify which areas and which information in an organisation are under threat. Then an effective TSCM strategy can be planned and implemented. Key questions are: how do you prevent installation and access to the site? How do you determine the effectiveness of existing security measures? And what action is required to promote overall security.
'How To Combat The Threat' covers the three main areas for planning a practical defence against technical surveillance: Surveying The Site, Assessing The Threat, The Plan of Action.
