Secure Active Directory

Practical guidance for understanding, auditing, and hardening Active Directory environments.

Technical articles, defensive guidance, PowerShell examples, and security resources for administrators, consultants, and defenders responsible for protecting Active Directory.

Active Directory remains a critical security boundary.

When Active Directory is misconfigured, attackers can often move quickly from a single compromised account to broad domain control.

Secure Active Directory focuses on practical, technically accurate guidance for identifying weaknesses, understanding attack paths, and improving defensive posture.
