Evading EDR vs Windows Security Internals: Which Should You Read?

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

The Definitive Guide to Defeating Endpoint Detection Systems

Matt Hand

A component-by-component teardown of how modern EDR sensors actually collect telemetry, and where each data source can be starved, blinded, or bypassed.

Windows Security Internals

A Deep Dive into Windows Authentication, Authorization, and Auditing

James Forshaw

Forshaw takes apart the Windows security model from the SRM and access tokens up through Kerberos, with live PowerShell you can run against your own machine. The most authoritative single source on how Windows actually decides who can do what.

Read this if

Red teamers and detection engineers who want to reason about EDR from the sensor up rather than copy-pasting the bypass of the week.

Vulnerability researchers, red teamers, and platform security engineers who need ground truth on tokens, SDs, logon, and the kernel security reference monitor.

Skip this if

Anyone wanting a turnkey list of working bypasses. Skip this if you don't run Windows or won't sit through the internals.

Anyone after a high-level overview or defensive playbook. This is mechanism, not policy, and it assumes you want to read SDDL by hand.

Key takeaways

EDR is a collection of telemetry sources, not a monolith; evasion means knowing which source sees what.
Most durable bypasses attack the sensor's data collection, not its detection logic.
Vendor-agnostic understanding outlives any specific bypass, which vendors patch fast.

Windows authorization is one coherent system once you see the SRM, tokens, and security descriptors as a single pipeline.
The author's NtObjectManager PowerShell toolkit turns abstract security theory into something you can poke at interactively.
Most Windows privilege-escalation bugs come from misunderstanding this model, not from exotic memory corruption.

How they compare

We rate Windows Security Internals higher (5/5 against 4/5 for Evading EDR). For most readers, that means Windows Security Internals is the primary pick and Evading EDR is a useful follow-up.

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

Evading EDR and Windows Security Internals both cover Offensive, so reading them in sequence reinforces the same material from different angles.
