Security Policy Framework
The Security Policy Framework is a set of high-level policies on security, mainly affecting the UK government and its suppliers.
The structure has changed over time. Version 11 was published in October 2013; it has 20 "Mandatory Requirements" grouped into four policy areas. Previously the SPF had as many as 70 Mandatory Requirements, which were more detailed, and which were grouped into 7 areas:
These mandatory requirements are a baseline which apply to all UK government departments; higher requirements may apply in some cases. Public-sector bodies are responsible for managing their own technical security risks, but can draw on expertise and guidelines provided by CESG and the Cabinet Office. The Centre for Protection of National Infrastructure also helps protect critical infrastructure. The Ministry of Defence has its own separate policies and systems.
The SPF superseded the Manual of Protective Security. Part of the SPF is produced by CESG, and part by the Cabinet Office's Security Policy Division.
