How Cybersecurity Really Works

A Hands-On Guide for Total Beginners

Sam Grubb

Sam Grubb's gentle, exercise-driven introduction for non-specialists who need a working mental model of attacker behaviour and basic defence.

Read this if

Software developers, junior AppSec engineers, and security champions who need a single, friendly book that covers the AppSec lifecycle without assuming security knowledge. Excellent as the first book to hand to a developer asked to lead AppSec for their team.

Non-engineers who need the field demystified. Grubb is the gentlest serious introduction in print: malware, phishing, network attacks, defenses, all explained in plain language without dumbing down.

Skip this if

Senior AppSec professionals who already have the lifecycle internalized; the book is a primer by design. Also relatively light on cloud-native AppSec specifics (IaC scanning, supply-chain attestation), which Janca's later writing covers more deeply.

Engineers, IT people, or anyone who already understands how the internet works. The book assumes nothing; for technical readers it'll feel slow.

Key takeaways

AppSec is a lifecycle discipline, not a scanning discipline; Janca's structure makes that argument by walking through each stage with concrete examples.
Most AppSec wins come from secure design and developer-relations work, not from finding more bugs at the end of the SDLC.
The book's tone is its underrated strength — many developers will finish this book; very few will finish a more formal AppSec textbook.

The chapter on threat modeling for individuals (not companies) is the one most teachers steal from: how to think about your own digital risk.
The hands-on labs at the end of each chapter make the book usable for actual classroom teaching, not just self-study.
Strikes the rare balance between respects-the-reader and explains-what-an-IP-address-is. Most beginner books fail one or the other.
