Episode 87 — Apply Windows Access Controls Correctly: NTFS, Shares, Registry, AD, and Privileges

This episode explains Windows access controls as layered enforcement mechanisms that must align, which is a common GSEC exam trap when questions mix NTFS permissions, share permissions, registry permissions, and directory-based authorization. You’ll learn how NTFS controls protect files and folders, how share permissions add an additional layer for network access, and why the effective permission is the intersection of both, not whichever looks more permissive in isolation. We’ll connect registry access to system integrity and persistence risk, and we’ll explain how Active Directory permissions and privilege assignments can enable powerful actions even when file access seems locked down. Scenarios include a file share exposed more broadly than intended, a user able to modify a service configuration through permissions inheritance, and a troubleshooting case where access is denied because of conflicting share and NTFS settings. Best practices emphasize role-based group assignment, minimal explicit denies, careful inheritance design, separation of administrative accounts, and verification of effective permissions using real access tests and logs rather than assumptions based on one configuration screen.
