To comply with the requirements of the Civil Contingency Act 2007 (the “Act”), a designated Operator of Essential Services (“OES”) must take appropriate and proportionate technical and organisational measures to manage the risks to the security of network and information systems, which support the delivery of essential services.

The Cyber Assessment Framework (“CAF”) was developed in accordance with section 54 of the Act, to provide guidance to OESs and particularly, to provide the GRA with the capability to assess the extent to which OESs are achieving the required levels of cyber security. The CAF is based on the UK’s framework and is used as a tool whereby the GRA liaises with the different OESs in order to tailor the CAF to each sector profile. 

The general CAF is based on the following four main objectives:

A: Managing security risk

B: Protecting against cyber attack

C: Detecting cyber security incidents

D: Minimising the impact of cyber security incidents

The CAF is further broken down into 14 specific principles that are based on sets of indicators of good practice.  These are:




Managing Security Risk

Risk Management

Asset Management

Supply Chain

Service Protection Policies and Processes

Defending systems against cyber attack

Identity and Access Control

Data Security

System Security

Resilient Networks & Systems

Staff Awareness & Training

Security Monitoring

Detecting cyber security events

Proactive Security Event Discovery

Response and Recovery Planning

Minimising the impact of cyber security incidents
