Advice & Guidance

Our advice & guidance outlines the steps to take when implementing protective security measures.

Last Updated 24 November 2018

The most effective way for an organisation to protect itself against national security threats is to use a combination of physical, personnel and people, and cyber security measures. For example an expensive swipe-card and PIN access control system is of little use if there are inadequate checks on who is given a pass in the first place. It will also fail if the system can be remotely accessed or bypassed.

CPNI’s protective security advice to the organisations that deliver the UK’s essential services is based on this principle. Multi-layering the different measures will provide the best mixture of deterrence and detection, and help to delay any attack.
