Building Secure and Reliable Systems

Best Practices for Designing, Implementing, and Maintaining Systems

Heather Adkins, Betsy Beyer, Paul Blankinship, Piotr Lewandowski, Ana Oprea, Adam Stubblefield

Google's site-reliability and security teams jointly write down what it actually takes to build systems that are both safe and dependable, from threat models and design reviews to rollback culture and crisis response.

Security Chaos Engineering

Sustaining Resilience in Software and Systems

Kelly Shortridge, Aaron Rinehart

Kelly Shortridge and Aaron Rinehart on treating security as a property of complex adaptive systems: instead of preventing failure, you continuously simulate it, and design the organization to learn from each result.

Read this if

Staff-and-up engineers, SREs, and security leads designing or operating systems where reliability and security must be argued for in the same room. The book treats safety and security as the same engineering discipline, which is the right model and almost nobody else publishes it.

Security architects, SREs, and platform engineers ready to abandon the prevention-first frame. Particularly strong for organizations that already practice chaos engineering for reliability and want to extend the discipline to security; the book is the bridge.

Skip this if

Readers who want a tooling tutorial or vendor-neutral checklists. The case studies are Google-shaped, and the patterns assume you have the discipline (postmortems, code review, paved roads) to execute them. If your org cannot stop a deploy, half the book will read as aspirational.

Practitioners working in heavily regulated environments where intentional production faults are not legal, or smaller organizations without the operational maturity to run game days safely. Also a poor first security book: it assumes you know what threat models, blast radius, and feedback loops are.

Key takeaways

Reliability and security share a common substrate: both are about designing for failure modes you cannot fully predict, and both decay if not exercised.
Recovery, not prevention, is the core skill of mature security organizations; the rollback, response, and recovery chapters are the heart of the book.
Most security wins come from boring infrastructure (paved roads, default-secure libraries, code review, sandboxing) rather than detection magic.

Security and reliability share the same root engineering problem: how to keep complex systems within tolerable bounds when the failure surface is unbounded.
Decision trees and effort-vs-impact analysis are operationalizable artifacts, not just blog material; the book teaches you to actually use them.
Continuous experimentation is more honest than tabletop exercises: production tells you what is true, runbooks tell you what someone wished were true.

How they compare

Building Secure and Reliable Systems and Security Chaos Engineering are both rated 5/5 in our catalog. Pick by topic preference and reading style rather than by rating.

Both books target advanced-level readers, so the choice is about topic, not difficulty.

Building Secure and Reliable Systems and Security Chaos Engineering both cover Security Architecture, Defensive, DevSecOps, so reading them in sequence reinforces the same material from different angles.
