Red Team: How to Succeed By Thinking Like the Enemy by Micah Zenko focuses on the role that red teaming plays in a variety of institutions, ranging from the Department of Defense to cybersecurity. It’s an excellent book that describes the thought process behind red teaming, when red teaming is a success and when it can be a failure, and the way a red team can best fit into an organization and provide value. If you’re looking for a book that’s highly technical or focused entirely on information security engineering, this book may disappoint. There’s only a single chapter covering the application of red teaming in the information security space (particularly “vulnerability probes” as Zenko refers to many of the tests), but that doesn’t make the rest of the content any less useful – or interesting – to the Red Team practitioner.
If there’s one thing I wish people from outside the security industry knew when dealing with information security, it’s that Security is not an absolute. Most of the time, it’s not even quantifiable. Even in the case of particular threat models, it’s often impossible to make statements about the security of a system with certainty.
