Tanya Janca Why did Tanya love this book?

Accelerate is a book about data. The authors used data collected during their PhD projects in order to prove The DevOps is effective.

They have all sorts of different ways to measure DevOps, it sufficiency, and the fact that way more projects succeed when you do DevOps, rather than waterfall methodology.

The book essentially show can be used as evidence of return on investment when modernizing your IT department. I am a person who loves data, and thus I absolutely love this book. Also, if you listen to the audiobook version, one of the authors reads it to you and her personality really shines through in a fun way.

I really enjoyed listening to Nicole read a book about to me about data!

Book cover of The Phoenix Project: A Novel about IT, DevOps, and Helping Your Business Win

George Finney Author Of Project Zero Trust: A Story about a Strategy for Aligning Security and the Business

From my list on books on cybersecurity that anyone can understand.

Why am I passionate about this?

I have worked in cybersecurity for over 20 years and think it’s one of the most important topics in our modern world. Everyone needs to be secure–from young kids to elderly people avoiding online scams. As a practicing Chief Security Officer, I work with security technology and people every day, and I’m getting to live my childhood dream of being a writer helping people understand these complex challenges. Security is a part of the foundation of Maslow’s Hierarchy of Needs and allows everyone to live up to their full potential as humans. People are the most important part of security, and you don’t need a degree in computer science to be cyber secure.

George's book list on books on cybersecurity that anyone can understand

George Finney Why did George love this book?

This book was one of the biggest inspirations for me when I wrote my book.

Running a team of technology experts is really hard, so instead of writing a reference manual or an inspirational leadership memoir, Kim tells the story of a group of people who work together to learn the same best practices that have been in use for decades in the manufacturing and project management industries.

This hits close to home since I can recognize myself and many of my colleagues in each of the vivid characters.

Book cover of Agile Application Security: Enabling Security in a Continuous Delivery Pipeline

Adam Shostack Author Of Threat Modeling: Designing for Security

From my list on application security for builders.

Why am I passionate about this?

Being able to understand and change reality through our knowledge and skill is literal magic. We’re building systems with so many exciting and unexpected properties that can be exploited and repurposed for both good and evil. I want to keep some of that magic and help people engineer – build great systems that make people’s lives better. I’ve been securing (and breaking) systems, from operating rooms to spaceships, from banks to self-driving cars for over 25 years. The biggest lesson I’ve learned is that if security is not infused from the start, we’re forced to rely on what ought to be our last lines of defense. This list helps you infuse security into your systems.

Adam's book list on application security for builders

Adam Shostack Why did Adam love this book?

When I worked in application security at Microsoft, we still had products that shipped every few years. I learned to scale application security in that world, but many people live in a different world now. AAS helped me understand which of our approaches translated well, which had to be transformed, and which needed to be discarded or replaced. I regularly refer back to it, even a few years later.

1 author picked Agile Application Security as one of their favorite books, and they share why you should read it.

What is this book about?

Agile continues to be the most adopted software development methodology among organizations worldwide, but it generally hasn't integrated well with traditional security management techniques. And most security professionals aren't up to speed in their understanding and experience of agile development. To help bridge the divide between these two worlds, this practical guide introduces several security tools and techniques adapted specifically to integrate with agile development.

Written by security experts and agile veterans, this book begins by introducing security principles to agile practitioners, and agile principles to security practitioners. The authors also reveal problems they encountered in their own experiences with…

From my list on software security engineering.

Why am I passionate about this?

As a kid, I used to do all the math problems in my textbooks just for fun, even if they weren’t part of a homework assignment. My grandchildren cringe when I tell them this. I am a researcher and educator in secure software engineering and have enjoyed a productive career in software development and management, software engineering and software security research, and software and secure software engineering education.

Book cover of Hacking: The Art of Exploitation

Nora Sandler Author Of Writing a C Compiler: Build a Real Programming Language from Scratch

From my list on systems and system failures for programmers.

Why am I passionate about this?

I love computers, and especially computer systems. I’m interested in how different pieces of hardware and software, like processors, operating systems, compilers, and linkers, work together to get things done. Early in my career, as a software security tester, I studied how different components interacted to find vulnerabilities. Now that I work on compilers, I focus on the systems that transform source code into a running program. I’m also interested in how computer systems are shaped by the people who build and use them—I believe that creating safer, more reliable software is a social problem as much as a technical one.

Nora's book list on systems and system failures for programmers

Nora Sandler Why did Nora love this book?

One of the best ways to understand how software works is to study how it fails. When I was just starting my career in software security, I read this book to learn about binary exploits like buffer overflows. It’s been a long time since I’ve written a binary exploit, but digging into the nitty-gritty, low-level details of how software runs on a real system has helped with everything I’ve done as an engineer since.

A lot has changed since this book was published in 2008 (and running the accompanying Live CD has gotten trickier), but the fundamental concepts are as relevant as ever.

By Jon Erickson,

1 author picked Hacking as one of their favorite books, and they share why you should read it.

What is this book about?

Hacking is the art of creative problem solving, whether that means finding an unconventional solution to a difficult problem or exploiting holes in sloppy programming. Many people call themselves hackers, but few have the strong technical foundation needed to really push the envelope. Rather than merely showing how to run existing exploits, author Jon Erickson explains how arcane hacking techniques actually work. To share the art and science of hacking in a way that is accessible to everyone, Hacking: The Art of Exploitation, 2nd Edition introduces the fundamentals of C programming from a hacker's perspective. The included LiveCD provides a…


Book cover of Battlefield Cyber: How China and Russia are Undermining Our Democracy and National Security

Michael Wolk

From my list on feed your internet paranoia.

Why am I passionate about this?

Researching DevilsGame, about an Internet meltdown caused by an unknown evil, I exposed myself to some harrowing truths. I learned how astonishingly frail our internet ecosystem is and how imperiled it is by bad actors who have burrowed deeply and often invisibly into its infrastructure. So, beyond writing a fictional thriller, I was moved to ring a warning bell! And I hope by formatting DevilsGame as “hyperlinked fiction,” mixing real news sites with fictional sites created for the novel, readers will experience the story in a way that parallels and parodies the way we experience real, live crises these days: navigating from fact to fiction, often without observing the boundaries.

Michael's book list on feed your internet paranoia

Michael Wolk Why did Michael love this book?

I was stunned by the authors' dire and dramatic warning that the interests and methods of two mighty authoritarian regimes–China and Russia–are increasingly coming into alignment, and this alignment is spawning increasingly deadly threats to, and attacks on, the very foundations of our democracy and national security.

I found myself agreeing as the authors demonstrate how the United States government is failing to fully acknowledge and effectively respond to these massive threats–but I was also somewhat encouraged, as they do offer solutions and provide a ray of hope that we can restructure our approach to Chinese and Russian threats by streamlining our bureaucratic agencies and purpose-building them to directly confront them.

1 author picked Battlefield Cyber as one of their favorite books, and they share why you should read it.

What is this book about?

The United States is being bombarded with cyber-attacks. From the surge in ransomware groups targeting critical infrastructure to nation states compromising the software supply chain and corporate email servers, malicious cyber activities have reached an all-time high. Russia attracts the most attention, but China is vastly more sophisticated. They have a common interest in exploiting the openness of the Internet and social media—and our democracy—to erode confidence in our institutions and to exacerbate our societal rifts to prevent us from mounting an effective response. Halting this digital aggression will require Americans to undertake sweeping changes in how we educate, organize…


Book cover of Data and Goliath: The Hidden Battles to Collect Your Data and Control Your World

Eric J. Rzeszut Author Of 10 Don'ts on Your Digital Devices: The Non-Techie's Survival Guide to Cyber Security and Privacy

From my list on to help you protect your personal information.

Why am I passionate about this?

I have been an information technology and cybersecurity professional for over two decades. I’ve learned over and over again that “people are the weakest link.” You can build the most secure system in the world, with stringent password requirements. But if the user writes their password down and leaves it where someone else can see it, system security is irrelevant! The easiest way to gain access to a system is via “social engineering” – to trick a human being into giving you the access you need, rather than trying to hack the system itself. The books on this list will help the reader lower their chances of being exploited like this.

Eric's book list on to help you protect your personal information

Eric J. Rzeszut Why did Eric love this book?

Security expert Bruce Schneier wrote this excellent book, talking about the “Goliaths” who are looking to exploit individuals’ data. Focusing more on politics (specifically US politics) than the other books on this list, Schneier talks about the Edward Snowden classified information reveal. He talks about mass surveillance conducted by the US and other governments around the world, and lays out in detail why this should concern us all.

By Bruce Schneier,

Why should I read it?

1 author picked Data and Goliath as one of their favorite books, and they share why you should read it.

What is this book about?

Data is everywhere. We create it every time we go online, turn our phone on (or off) or pay with a credit card. This data is stored, studied, bought and sold by companies and governments for surveillance and for control. "Foremost security expert" (Wired) Bruce Schneier shows how this data has led to a double-edged Internet-a Web that gives power to the people but is abused by the institutions on which those people depend.

In Data and Goliath, Schneier reveals the full extent of surveillance, censorship and propaganda in society today, examining the risks of cybercrime, cyberterrorism and cyberwar. He…


Book cover of Infrastructure as Code: Dynamic Systems for the Cloud Age

Yevgeniy Brikman Author Of Fundamentals of DevOps and Software Delivery: A Hands-On Guide to Deploying and Managing Software in Production

From my list on practical, hands-on books on DevOps and software delivery.

Why am I passionate about this?

I’ve spent more than a decade working on infrastructure, from my early days at LinkedIn, where we had to do a massive DevOps transformation to save the company, to co-founding Gruntwork, where I had the opportunity to work with hundreds of companies on their software delivery practices. From all of this, I can say the following with certainty: the DevOps best practices that a handful of the top tech companies have figured out are not filtering down to the rest of the industry. This is making the entire software industry slower, less effective, and less secure—and I see it as my mission to fix that.

Yevgeniy's book list on practical, hands-on books on DevOps and software delivery

Yevgeniy Brikman Why did Yevgeniy love this book?

This is a book for practitioners, by a practitioner, full of practical learnings that I was able to start using in my work immediately.

I especially appreciated the parts teaching the core principles of infrastructure as code (e.g., systems are disposable, consistent, can easily be reproduced, etc.), core practices of infrastructure as code (e.g., use definition files, self-documented systems and processes, version all the things, etc.), and the idea of antifragile systems (rather than just systems that you prevent from breaking) and autonomic systems (rather than just automated systems).

1 author picked Infrastructure as Code as one of their favorite books, and they share why you should read it.

What is this book about?

Six years ago, Infrastructure as Code was a new concept.
