Cyber Security All-in-One, Volume 1: Foundations and Threats: Security Principles, Threat Actors, Attack Lifecycles, Networks, Endpoints, Cryptography

By Prof Kai London

Security fails at the foundations, or it does not fail at all.

Volume 1 builds the complete mental model every practitioner needs: what the modern threat landscape actually is, how attacks really develop from reconnaissance to impact, and how principles like least privilege and defence in depth become engineering decisions a reviewer can inspect.

Twenty chapters carry you from core security principles through threat actors, social engineering, malware and vulnerability exploitation, into networks, segmentation, firewalls and detection, then operating systems, endpoints and virtualisation, then cryptography, PKI and key management - closing with threat modelling, secure design review and zero trust architecture.

Every chapter is built on a real incident
Colonial Pipeline told accurately, not as the myth. The expired certificate that blinded Equifax's inspection for seventy-six days. The deepfake video call that moved twenty-five million dollars. Change Healthcare's missing multi-factor authentication. Log4Shell, NotPetya, WannaCry - and the outage that proved availability is a security property.

Every chapter gives you something to use
In this chapter - what you will be able to do by the end of it
Opening scenario - a real-shaped organisation, under pressure, in real time
Plain-English explanation - the mechanism before the acronym, no assumed knowledge
Technical deep dive - engineer-grade depth you can act on
From the headlines - one verified public incident, separating confirmed fact from what is popularly misremembered
Controls and mitigations - what to do, and the evidence that proves you did it
The board translation - the same subject in money, liability and decision language
Practitioner checklist - take it into the office on Monday
Review questions - with answers that teach

Plus reference apparatus you will actually reopen
Nine original framework diagrams. A field toolkit of working templates. Worked technical examples - a STRIDE threat model, a firewall rule review, a TLS configuration review, a key rotation schedule. A glossary of over 130 terms. A page-accurate index.

Written for security engineers, network engineers, architects, consultants, technical managers, and anyone preparing for senior security roles.

Assume the breach. Prove the control. Command the response.
