The Art of Software Security Assessment

Identifying and Preventing Software Vulnerabilities

Mark Dowd, John McDonald, Justin Schuh

The 1200-page reference on auditing C/C++ codebases for security: parsing complex memory and integer interactions, language pitfalls, and how vulnerabilities arise from interactions between layers.

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

Auditors, vulnerability researchers, and developers of C/C++ codebases. The deepest book in print on reading code adversarially. Old, dense, and still unsurpassed.

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

Web developers, anyone working in memory-safe languages exclusively, or beginners with no C/C++ exposure. The book is a 1,200-page audit primer; nothing else competes for depth.

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

Vulnerability classes (memory corruption, integer issues, format strings, race conditions) arise from interactions between layers; the book teaches you to see the boundaries.
The chapter on integer issues is the canonical reference; most public CVEs in C/C++ codebases through 2025 still trace back to patterns Dowd/McDonald/Schuh named here.
The case studies (Apache, Postfix, Solaris, OpenSSL) make the abstractions concrete; reading them in order builds the auditor's eye nothing else does.

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

The Art of Software Security Assessment 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.

The Art of Software Security Assessment and Windows Security Internals both cover Vulnerability Research, so reading them in sequence reinforces the same material from different angles.
