Windows Internals, Part 1

System architecture, processes, threads, memory management, and more

Pavel Yosifovich, Alex Ionescu, Mark Russinovich, David Solomon

The canonical Microsoft Press reference on Windows internals: how processes, threads, memory and system services are actually implemented in the modern Windows kernel. User-mode focus in this volume.

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

Windows malware analysts, kernel reverse engineers, OS-level developers, and anyone whose security work requires understanding the platform at depth. Russinovich's name is on the cover for a reason; this is the canonical reference for what Windows actually does.

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

Beginners or readers without programming background. The book is dense, lengthy, and assumes Win32 API fluency at minimum. Read after Practical Reverse Engineering, not before.

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

Process, thread, and memory management on Windows have specific shapes that don't transfer from Linux mental models; the chapters on each are the canonical authority.
Object Manager and the kernel handle table are the two concepts most malware analysts wish they'd understood earlier; the book is where to learn them.
User-mode security boundaries (token, ACL, integrity levels, AppContainer) are the layer where most modern Windows exploits operate; the book maps the surface.

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

Windows Internals, Part 1 and Windows Security Internals 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.

Windows Internals, Part 1 and Windows Security Internals both cover Windows Internals, so reading them in sequence reinforces the same material from different angles.
