The Cyber Security Body Of Knowledge

A comprehensive Body of Knowledge to inform and underpin education and professional training for the cyber security sector

The CyBOK project aims to bring cyber security into line with the more established sciences by distilling knowledge from major internationally-recognised experts to form a Cyber Security Body of Knowledge that will provide much-needed foundations for this emerging topic. The project, funded by the National Cyber Security Programme, is led by the University of Bristol's Professor Awais Rashid, along with other leading cyber security experts - including Professor Andrew Martin, Professor George Danezis, Professor Emil Lupu and Dr Howard Chivers.

Following wide community consultation with both academia and industry, key knowledge areas (KAs) have been identified to form the scope of the CyBOK. The Scope document provides an overview of these top-level KAs and the sub-topics that should be covered under each.

Draft Knowledge Areas (KAs) released for comment

We are very pleased to announce the release of further KAs, Cyber-Physical Systems Security, Malware and Physical Layer & Telecommunications Security for public review. You are invited to contribute to the development of the KAs by sending your comments to the CyBOK project team. All contributions, big or small, are welcomed so please input yourself and feel free to forward this invitation to any other interested parties.
