Preface

Cybersecurity is quickly becoming a make or break topic area for most businesses. We can all cite numerous examples from the headlines that underscore the importance of security: this includes security issues at both large and small companies, breach notifications from the online services we use, and incidents in the companies we work with and for. We all know stories of vulnerable software, scammed users, accidental misconfiguration of hardware or software, and numerous other events that can and do have potentially disastrous consequences for both individuals and organizations.

All of this is happening against a backdrop where artificial intelligence (AI) and machine learning (ML) are becoming ubiquitous and changing how we do things. ...
