The term ‘protective security’ is, in reality, an umbrella term for a multifaceted approach aimed at safeguarding society: communities, individuals, infrastructure; buildings and assets, information and knowledge from a range of threats including criminality, organised crime, cybercrime, violent protest, terrorism and hostile state activity.
Protective security encompasses the combination and multi-layering of appropriate and proportionate Physical, Personnel and Cyber Security measures to help identify and respond to any attack. Security requirements will change accordingly with the locally identified threats and vulnerabilities.

PSPF Standards detail additional mandatory requirements on specific PSPF topics. They are more granular and prescriptive in nature.
