From Data to Action

Michael Collins

Michael Collins on building situational awareness from network telemetry: collection architecture, statistical baseline-setting, and the analytic patterns that turn raw flows into detection.

Zero Trust Networks

Building Secure Systems in Untrusted Networks

Evan Gilman, Doug Barth

Evan Gilman and Doug Barth's pre-marketing-bubble treatment of zero-trust architecture — what it is when you actually implement it (trust evaluation, device identity, dynamic policy) versus what the vendor pitch turned it into.

Read this if

Detection engineers and SOC analysts who've graduated from "what alert is this" to "is this alert worth triaging at all." Collins is the quantitative-detection text the field needed.

Architects and platform engineers tasked with implementing zero-trust without buying a product called Zero Trust. The book is the rare resource that walks through the engineering substrate — service identity, attestation, policy decision points — instead of the marketing.

Skip this if

Beginners with no NSM background, or readers who only do log-based detection. The book leans heavily on flow data and statistical thinking; pair with The Practice of Network Security Monitoring (Bejtlich) first if you're new to the discipline.

Readers wanting current vendor-comparison or specific cloud-native zero-trust (BeyondCorp, Tailscale, Cloudflare Access, Tetragon) detail. The 2017 publication pre-dates almost all of the productized zero-trust marketplace; the principles are durable, the products are not.

Key takeaways

Detection engineering at scale is a statistical problem; the book teaches the framing every modern SOC eventually reinvents.
Flow-data analytics (NetFlow / IPFIX / sFlow) catch lateral movement that packet-based detection misses; the book is the cleanest treatment in print.
Time-series anomaly detection can be done well with off-the-shelf tooling and clear thinking; the chapters on baseline calibration are the practical core.

Zero trust is a property of the architecture, not a product; the book makes this case convincingly enough that it should be the first read for anyone leading a ZT initiative.
Device and workload identity are the load-bearing layer most ZT deployments under-invest in.
Migration is the project — most organizations cannot adopt zero trust without a multi-year incremental plan, and the book's chapters on incremental rollout are the most useful in practice.

How they compare

Network Security Through Data Analysis and Zero Trust Networks are both rated 4/5 in our catalog. Pick by topic preference and reading style rather than by rating.

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

Network Security Through Data Analysis and Zero Trust Networks both cover Defensive, Networking, so reading them in sequence reinforces the same material from different angles.
