Why Confident Cyber Security?

"An essential book for anyone who wants a career in cybersecurity"

Jane Frankland, Entrepreneur & Author

The world is more digitally connected than ever before, and with this connectivity, comes vulnerability. It is therefore vital that all professionals understand cyber risk and how to minimise it. This means that cyber security skills are in huge demand, and there are vast career opportunities to be taken. 

Confident Cyber Security is here to help. Written by expert author and speaker, Dr Jessica Barker, this jargon-busting guide will give you a clear overview of the world of cyber security. Exploring everything from the human side to the technical and physical implications, this book takes you through the fundamentals: how to keep secrets safe, how to stop people being manipulated and how to protect people, businesses and countries from those who wish to do harm. With a dedicated section on what it could mean for you, let Confident Cyber Security give you that cutting-edge career boost you seek.

"What a great read and resource this book is… not only for those that are exploring the topic for the first time... but also for all leaders wrestling with still being “beginners” in the world of Cyber"

Simon Legg
