What it means to trust in the context of computer and network security

Just over two years ago, I agreed a contract with Wiley to write a book about trust in computing. It was a long road to get there, starting over twenty years ago, but what pushed me to commit to writing something was a conference I’d been to earlier in 2019 where there was quite a lot of discussion around “trust”, but no obvious underlying agreement about what was actually meant by the term. “Zero trust”, “trusted systems”, “trusted boot”, “trusted compute base” – all terms referencing trust, but with varying levels of definition, and differing understanding if what was being expected, by what components, and to what end.

I’ve spent a lot of time thinking about trust over my career and also have a major professional interest in security and cloud computing, specifically around Confidential Computing (see Confidential computing – the new HTTPS? and Enarx for everyone (a quest) for some starting points), and although the idea of a book wasn’t a simple one, I decided to go for it. This week, we should have the copy-editing stage complete (technical editing already done), with the final stage being proof-reading. This means that the book is close to down. I can’t share a definitive publication date yet, but things are getting there, and I’ve just discovered that the publisher’s blurb has made it onto Amazon. Here, then, is what you can expect.


Learn to analyze and measure risk by exploring the nature of trust and its application to cybersecurity 

Trust in Computer Systems and the Cloud delivers an insightful and practical new take on what it means to trust in the context of computer and network security and the impact on the emerging field of Confidential Computing. Author Mike Bursell’s experience, ranging from Chief Security Architect at Red Hat to CEO at a Confidential Computing start-up grounds the reader in fundamental concepts of trust and related ideas before discussing the more sophisticated applications of these concepts to various areas in computing. 

The book demonstrates in the importance of understanding and quantifying risk and draws on the social and computer sciences to explain hardware and software security, complex systems, and open source communities. It takes a detailed look at the impact of Confidential Computing on security, trust and risk and also describes the emerging concept of trust domains, which provide an alternative to standard layered security. 

  • Foundational definitions of trust from sociology and other social sciences, how they evolved, and what modern concepts of trust mean to computer professionals 
  • A comprehensive examination of the importance of systems, from open-source communities to HSMs, TPMs, and Confidential Computing with TEEs. 
  • A thorough exploration of trust domains, including explorations of communities of practice, the centralization of control and policies, and monitoring 

Perfect for security architects at the CISSP level or higher, Trust in Computer Systems and the Cloud is also an indispensable addition to the libraries of system architects, security system engineers, and master’s students in software architecture and security.
