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

Welcome to CyBOK, the Cybersecurity 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.

Welcome to CyBOK with Awais Rashid

The purpose of this Secure Software Lifecycle knowledge area is to provide an overview of software development processes for implementing secure software from the design of the software to the operational use of the software.
We speak with CyBOK Secure Software Lifecycle Knowledge Area author Laurie Williams for an introductory overview of the topic.

After nearly 40 years of research and development, the Security Operations and Incident Management domain has reached a sufficient maturity to be deployed in many environments.
We speak with CyBOK Security Operations and Incident Management Knowledge Area author Hervé Debar for an introductory overview of the topic.

The purpose of this chapter is to explain the various aspects of cryptography which we feel should be known to an expert in cyber-security.

We speak with CyBOK Cryptography Knowledge Area author Nigel Smart for an introductory overview of the topic.

The purpose of the Software Security chapter is to provide a structured overview of known categories of software implementation vulnerabilities, and of techniques that can be used to prevent or detect such vulnerabilities, or to mitigate their exploitation.
We speak with CyBOK Software Security Knowledge Area author Frank Piessens for an introductory overview of the topic.

Cyber-Physical Systems Security are engineered systems that are built from, and depend upon, the seamless integration of computation, and physical components. While automatic control systems like the steam governor have existed for several centuries, it is only in the past decades that the automation of physical infrastructures like the power grid, water systems, or chemical reactions have migrated from analogue controls to embedded computer-based control, often communicating through computer-based networks.
We speak with CyBOK Cyber-Physical Systems Security author Alvaro Cardenas for an introductory overview of the topic.

The Forensics chapter provides a technical overview of digital forensic techniques and capabilities, and to put them into a broader perspective with regard to other related areas in the cybersecurity domain. The discussion on legal aspects of digital forensics is limited only to general principles and best practices, as the specifics of the application of these principles tend to vary across jurisdictions.
We speak with CyBOK Forensics author Vassil Roussev for an introductory overview of the topic.

The Risk Management and Governance chapter explains the fundamental principles of cyber risk assessment and management and their role in risk governance, expanding on these to cover the knowledge required to gain a working understanding of the topic and its sub-areas.
We speak with CyBOK Risk Management and Governance author Pete Burnap for an introductory overview of the topic.

The Authentication, Authorisation & Accountability (AAA) chapter presents the general foundations of access control and some significant instantiations that have emerged as IT kept spreading into new application areas. It will survey modes of user authentication and the way they are currently deployed, authentication protocols for the web, noting how new use cases have led to a shift from authentication to authorisation protocols, and the formalisation of authentication properties as used in today’s protocol analysis tools. On accountability, the focus is on the management and protection of audit logs.
We speak with CyBOK Authentication, Authorisation & Accountability (AAA) author Dieter Gollmann for an introductory overview of the topic.

The Human Factors chapter presents a foundational understanding of the role of human factors in cyber security. One key aspect of this is how to design security that is usable and acceptable to a range of human actors, for instance, end-users, administrators and developers. This knowledge area also introduces a broader organisational and societal perspective on security that has emerged over the past decade.
We speak with CyBOK Human Factors co-author Awais Rashid for an introductory overview of the topic.

The purpose of the Operating Systems & Virtualisation Security chapter is to introduce the principles, primitives and practices for ensuring security at the operating system and hypervisor levels. We see that the challenges related to operating system security have evolved over the past few decades, even if the principles have stayed mostly the same.
We speak with CyBOK Operating Systems & Virtualisation Security author Herbert Bos for an introductory overview of the topic.

The purpose of the Network Security chapter is to explain the challenges associated with securing a network under a variety of attacks for a number of networking technologies and widely used security protocols, along with emerging security challenges and solutions. This chapter aims to provide the necessary background in order to understand other knowledge areas. An understanding of basic networking protocol stack and TCP/IP suite is assumed.
We speak with CyBOK Network Security Knowledge Area author Sanjay Jha for an introductory overview of the topic.

The purpose of the Privacy and Online Rights chapter is to introduce system designers to the concepts and technologies that are used to engineer systems that inherently protect users’ privacy. We aim to provide designers with the ability to identify privacy problems, to describe them from a technical perspective, and to select adequate technologies to eliminate, or at least, mitigate these problems.
We speak with CyBOK Privacy and Online Rights Knowledge Area author Carmela Troncoso for an introductory overview of the topic.

The purpose of the Distributed Systems Security chapter is to introduce the different classes of distributed systems categorising them into two broad categories of decentralised distributed systems (without central coordination) and the coordinated resource/services type of distributed systems. Subsequently, each of these distributed system categories is expounded for the conceptual mechanisms providing their characteristic functionalities prior to discussing the security issues pertinent to these systems.
We speak with CyBOK Distributed Systems Security author Neeraj Suri for an introductory overview of the topic.

The purpose of the Distributed Systems Security chapter covers a broad range of topics from trusted computing to Trojan circuits. To classify these topics we follow the different hardware abstraction layers as introduced by the Y-chart of Gajski & Kuhn.
We speak with CyBOK Hardware Security author Ingrid Verbauwhede for an introductory overview of the topic.

The purpose of the Adversarial Behaviours chapter is to provide an overview of the malicious operations that are happening on the Internet today. The chapter discusses how these frameworks can be used by researchers and practitioners to develop effective mitigations against malicious online operations.
We speak with CyBOK Distributed Systems Security author Gianluca Stringhini for an introductory overview of the topic.

The purpose of the Law and Regulation chapter is to provide a snapshot of legal and regulatory topics that merit consideration when conducting various activities in the field of cyber security such as: security management, risk assessment, security testing, forensic investigation, research, product and service development, and cyber operations (defensive and offensive). The hope is to provide a framework that shows the cyber security practitioner the most common categories of legal and regulatory risk that apply to these activities, and to highlight (where possible) some sources of legal authority and scholarship..
We speak with CyBOK Law and Regulation author Robert Carolina for an introductory overview of the topic.
