Building Secure and Reliable Systems vs Container Security: Which Should You Read?

Two cybersecurity books on DevSecOps, compared honestly: who each is for, what each does best, and which to read first.

Advanced

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.

Container Security

Fundamentals for Securing Containerized Applications

Liz Rice

Liz Rice's first-principles introduction to how Linux containers actually work — namespaces, cgroups, capabilities, seccomp, image layering — and the security implications that fall out of those mechanics.

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.

Engineers and security people who use containers daily but treat them as boxes. The book is the rare introduction that explains containers as compositions of Linux primitives rather than as a Docker-shaped product, and that is exactly what makes the security argument legible.

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.

Readers needing in-depth Kubernetes, supply-chain (SLSA, in-toto, Sigstore), or cloud-runtime-specific (Fargate, Cloud Run, ECS) coverage; pair with the Kubernetes books and current SLSA documentation. Also light on Wasm-runtime alternatives, which are an increasing fraction of the field.

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.

A container is not a box; it is a process with curated views of namespaces and resources, and most container vulnerabilities live in the gap between that mental model and the box mental model.
Capability dropping, read-only root filesystems, and seccomp profiles are not optional — Rice makes the case persuasively with concrete examples.
Image-supply-chain hygiene is half the security story; the book pre-dates SLSA but motivates it cleanly.

How they compare

We rate Building Secure and Reliable Systems higher (5/5 against 4/5 for Container Security). For most readers, that means Building Secure and Reliable Systems is the primary pick and Container Security is a useful follow-up.

Building Secure and Reliable Systems is pitched at advanced level. Container Security is pitched at intermediate level. Read the easier one first if you're not yet comfortable with the topic.

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