1 Scope
This document provides guidelines to organizations for establishing the basic elements, strategies and processes for preventing and reducing crime and the fear of crime at a new or existing built environment. It recommends the establishment of countermeasures and actions to treat crime and security risks in an effective and efficient manner by leveraging environmental design. Within this document, the term “security” is used in a broad manner to include all crime, safety and security-specific applications, so it is applicable to public and private organizations, regardless of type, size or nature. While this document provides general examples of implementation strategies and best practices, it is not intended to provide an exhaustive listing of detailed design, architectural or physical security crime prevention through environmental design (CPTED) implementation strategies or restrict the potential applications to only those examples provided in this document.

3.1 crime prevention through environmental design
process for analysing and assessing crime and security risks to guide development, urban design, site management and the use of the built environment in order to prevent and reduce crime and the fear of crime, and to promote and improve public health, quality of life and sustainability
Note 1 to entry: Environmental design refers to the applied arts and sciences dealing with creating the human-designed environment.

5 Basics of CPTED
5.1 Key considerations of CPTED
The organization should:
— base its crime prevention and security strategies on understanding crime opportunities;
— identify the following four considerations at the beginning stage of a project:
— where: the exact location and the type of area;
— what: the crime problems occurring in the area now or in the future;
— who: the interested parties involved in the area;
— how: the treatment of crime and security risks (e.g. countermeasures) in an effective and efficient manner.
NOTE Annex A provides additional information on the key considerations of CPTED.
5.2 CPTED strategies
5.2.1 General
The organization should:
— understand that there are two different CPTED concepts:
— physical CPTED (or first generation CPTED) concept;
— social CPTED (or second generation CPTED) concept;
— consider physical CPTED strategies as well as social CPTED strategies.
