The world is more digitally connected than ever before and, with this connectivity, comes vulnerability. This book will equip you with all the skills and insights you need to understand cyber security and kickstart a prosperous career.

Confident Cyber Security is here to help. 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.

Featuring real-world case studies including Disney, the NHS, Taylor Swift and Frank Abagnale, this book is packed with clear explanations, sound advice and practical exercises to help you understand and apply the principles of cyber security. This new edition covers increasingly important topics such as deepfakes, AI and blockchain technology.

Network segmentation is a very important element in an organization’s defences, based on the understanding that organizations must not only try to protect against being attacked, but also put in place damage limitation for if (or when) they are breached. Network segmentation means that if one part of an organization or its network is compromised, this compromise can be contained and not infect the whole. This also allows for logical segmentation of an organization, so that different departments have different segments. It works in conjunction with what is called the ‘least privilege’ principle – that users can only access the minimum that they need in order to do their work – meaning that access to information can be structured more easily on a need to know basis. It also allows for better monitoring and auditing of access to information.

When a segmented network is not enough and more control is required over a system or some particular information, organizations will build an airgapped network, meaning a network that does not touch the internet or any other part of the existing network. An airgapped network is a standalone, solitary system that is built to resist infection from outside. Airgapped systems are used in the military, defence firms and industrial control systems.
