Building a Secure Active Directory

Attackers Target Active Directory Every Day
Learn How to Build & Secure It — Step-by-Step

Active Directory is the backbone of Windows environments — and one of the most targeted by attackers. A single misconfiguration can open the door to privilege escalation, lateral movement, and complete domain compromise.

Designed for IT admins, security engineers, and system administrators, this hands-on course shows you exactly how to build, harden, and secure AD from the ground up — using Microsoft best practices and real-world defenses:

Practical lab build — create your own AD environment with Hyper-V or VMware, just like in production.
Step-by-step hardening — implement Kerberos armoring, Tiering Model, LAPS, security baselines & more.
Real-world skills — learn by doing, so you can secure AD in your organization with confidence.

In 2 days build your own fully hardened AD environment — and keep it for testing, validation, and future projects.

Why This Course?

Most AD environments are built without security in mind — leaving hidden escalation paths, weak configurations, and unprotected admin accounts. Attackers know exactly how to exploit these gaps.

This course shows you how to build Active Directory the right way — secure from day one — so you don’t spend years patching mistakes.

Spot and remove weak configurations before attackers find them
Apply security controls that block real-world AD attacks
Build a hardened environment you can replicate in production



Who Should Take This Course?

🚫 Not for complete beginners. This course is designed for IT pros who already have basic Windows & Active Directory knowledge.

Windows Administrators & Engineers → Build AD securely from the ground up using Microsoft best practices.
Cybersecurity Engineers & SOC Analysts → Learn how to harden AD against modern attacks and spot weak configurations.
IT Managers & Security Leads → Create a secure reference lab for testing and validating configurations before production rollout.
Pentesters & Ethical Hackers → Understand hardened AD environments and the defenses that stop common attack paths.



What You’ll Learn

Master Active Directory hardening—build it right from the start, apply proven defenses, and secure it like a production environment.

Building the Environment

Create your own AD lab from scratch — from Hyper-V setup to a fully functional domain
Configure domain controllers, DNS, Sites & Services, and tiered administration hosts
Simulate real-world infrastructure with WSUS, file server, and workstation

Hardening Active Directory

Secure admin accounts & implement the Tiering Model
Apply Kerberos armoring, LAPS, and advanced password policies
Enforce Microsoft security baselines and Advanced Audit Policy
Deploy Sysmon & logging to detect malicious activity
Restrict delegation, secure domain join privileges, and remove risky legacy groups

Testing & Validation

Validate defenses against common attack techniques
Ensure hardened configurations block privilege escalation & lateral movement
Build a permanent, reusable lab for ongoing testing and skill mastery


🎁 Bonus:
Includes PDF guides, configuration checklists, and practical tips from real-world security audits.



System Requirements

This course is fully hands-on — you’ll build your own AD lab on your hardware.
No rented cloud labs — you keep your environment forever for testing & experiments.

💻 Recommended setup:

32 GB RAM
External SSD for fast VM storage
Run 3–4 VMs at once (each with 2 vCPUs & 4 GB RAM, dynamic)
Example: Intel Xeon Silver 4110 CPU 2.10 GHz — 8 Cores / 16 Threads = 128 vCPUs
~230 GB total disk space for all virtual machines

Works best on Hyper-V, but VMware & others are fine.
 You can also run a smaller 2-VM version for limited testing.

Why Learn With Me?

 Taught by a Microsoft Most Valuable Professional (MVP) and Cybersecurity Engineer with 8+ years of experience.

I started as a Windows Administrator—learning security the hard way. That’s why this course gives you practical, real-world insights, not just theory. It’s the training I wish I had.

 Real-world insights, not just theory.
 
Focused on practical security—fix misconfigurations, detect attackers, and protect infrastructure.

Course Syllabus

In this chapter we are going to prepare our environment for the installation of Active Directory Domain Services:

  • Download installation media
  • Install Hyper-V role
  • Prepare Virtual Network Switches
  • Prepare Virtual Machines
  • Configure Virtual Machines

In this chapter we are going to install and configure Active Directory Domain Services:

  • Install Active Directory Domain Services role
  • Configure a time source for the domain
  • Set Disaster Services Restore Mode password
  • Prepare T0 administration host
  • Configure DNS
  • Configure Sites and Services

Now it is time to secure our Active Directory according to best practices. You will learn to implement following best practices:

  • Secure Administrator Account
  • Implement Tiering Model
  • Use Protected Users Group
  • Create multiple Password Policies
  • Implement Kerberos Armoring
  • Implement Security Baselines
  • Install LAPS
  • Set Advanced Audit Policy Configuration
  • Install Sysmon
  • Secure Domain Join Privileges
  • No Trusts (informative only)
  • Enable Recycle Bin
  • Configure Pre-Windows 2000 Compatible Access Group

During this chapter we finally get to proper testing of our newly built and hardened Active Directory. Following will be tested:

  • Domain join operation
  • Tiering model and restrictions
  • Security Baselines
  • Removal of members from the Pre-Windows 2000 Compatible Access Group

We will also expand our infrastructure with few other devices and roles to go even further:

  • Windows Server Update Services (WSUS)
  • File Server with Group Managed Service Account (GMSA)
  • Workstation

In this chapter, we step back from the lab and look at the bigger security picture. You’ll see examples of what comes after building and hardening Active Directory, such as:

  • Expanding security beyond AD to include backups, monitoring, and advanced threat detection.
  • Preparing for disaster recovery and incident response scenarios.
  • Considering organizational processes like documentation, vulnerability assessments, and penetration testing.
  • Exploring advanced access controls, PAM, and JIT.
