Grey space is a term used to describe the areas where the public and private environments overlap. These are places that appear normal and safe, but are often exploited by hostile individuals to plan or launch attacks. This module introduces the concept of grey space, explains why it matters in the modern terrorist threat landscape, and shows how Security Control Room (SCR) operators must recognise and respond to risks in these areas.
