CyBOK - Security Informed Safety with Victor Lough
In this topic guide we set out the present state of thinking on how to combine the perpectives of cyber security and safety and reliability cultures. In particular, we focus on a structured approach to defending safety critical systems, with mechanisms already in place for safety and reliability. In other words, we do not start with the assumption of greenfield sites and recognise that security cu
CyBOK - Cloud Security with Mark Buckwell
Adoption of cloud computing has accelerated the digital transformation of organisations globally, supported by a corresponding transformation in cybersecurity. With the migration of applications from on-premise data centres to the public cloud and their integration with edge environments, the threats to processing sensitive data have changed. The cloud platform's built-in security has mitigated th
CyBOK - AI for Security with Matilda Rhode
Cybersecurity, like other industries, has seen an explosion in the use of artificial intelligence (AI) and machine learning (ML) technologies in recent years. AI and ML can help to automate tasks. Data-driven approaches in general can draw patterns from vast volumes of data far quicker than humans are can. This episode summarises the state of AI for security at the time of writing and highlights s
CyBOK - Security Economics with Tyler Moore
The Security Economics Knowledge Guide introduces some of the most impactful ways economics has helped to shed light on cybersecurity problems and frame solutions that blend private and public action. The guide focuses on the organizational, rather than individual, perspective, which is where the majority of scholarly activity has focused.

CyBOK - Network Security 2.0 with Christian Rossow
The ubiquity of networking allows us to connect all sorts of devices and gain unprecedented access to a whole range of applications and services anytime, anywhere. However, our heavy reliance on networking technology also makes it an attractive target for malicious users who are willing to compromise the security of our communications and/or cause disruption to services that are critical for our d
CyBOK - Formal Methods with David Basin
The Formal Methods knowledge area surveys the most relevant topics in formal methods for security. As a discipline, formal methods address foundations, methods and tools, based on mathematics and logic, for rigourously developing and reasoning about computer systems, whether they be software, hardware, or a combination of the two. The application of formal methods to security has emerged over rece
CyBOK - Applied Cryptography with Kenny Paterson
The Applied Cryptography knowledge area This document provides a broad introduction to the field of cryptography, focusing on applied aspects of the subject. It complements the CyBoK document [1] which focuses on formal aspects of cryptography (including definitions and proofs) and on describing the core cryptographic primitives. That said, formal aspects are highly relevant when considering appli
