Just like where IT Service Management had to be liberated from an IT-only focus and become Enterprise Service Management, Cybersecurity (or rather, Information Security) has to be liberated from a technology-only focus and establish itself as an intrinsic part of an organisation's business.
This book does a good job refocusing InfoSec executives to the business landscape. It forces (prospective) InfoSec leaders to look beyond the usual technological controls and tells them to look at their role from a business perspective. And it is modern, discussing current events (COVID-19) and topics (digital transformation), unlike the old CISSP and CISM type of manuals.
That said, there are some odd sections in here that InfoSec executives should alfeady be familiar with: a whole chapter on basic risk management and a job interviewing guide. The gung-ho style of writing may put off some readers as well.
Overall, this book is recommended for InfoSec leaders that have trouble escaping from a technical pigeon hole and want to be a more integral part of the business.
