Tableaux de bord de la sécurité réseau vs Zero Trust Networks: Which Should You Read?

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

Tableaux de bord de la sécurité réseau

Cédric Llorens, Laurent Levier, Denis Valois

A practitioner's manual for measuring and steering network security — metrics, dashboards, monitoring and risk indicators — for the people who run security operations.

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

Network and security engineers, and security managers who need to instrument and report on security: what to measure, how to build dashboards, how to track risk over time.

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

Readers wanting attacks or the latest cloud-native tooling; it's an operations-and-metrics book whose editions predate much of the modern stack.

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

A rare French book focused on measuring security — metrics, indicators and dashboards, not exploits.
Written for security operations and management: how to make security legible to the organisation.
The principles of security measurement endure; check the specific tooling against current practice.

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

We rate Zero Trust Networks higher (4/5 against 3/5 for Tableaux de bord de la sécurité réseau). For most readers, that means Zero Trust Networks is the primary pick and Tableaux de bord de la sécurité réseau is a useful follow-up.

Tableaux de bord de la sécurité réseau is pitched at advanced level. Zero Trust Networks is pitched at intermediate level. Read the easier one first if you're not yet comfortable with the topic.

Tableaux de bord de la sécurité réseau and Zero Trust Networks both cover Networking, Defensive, so reading them in sequence reinforces the same material from different angles.
