To provide a more detailed guide for setting up an Active Directory (AD) domain `homelab.local` tailored for your home environment, including a cybersecurity lab, home LAN/WLAN, NAS, laptops, IT equipment, and servers, we’ll delve deeper into the specifics. This setup aims to enhance management, security, and operational efficiency across all devices and users in your home network.

## Detailed Active Directory Domain Setup for Home Use

### Domain Name: `homelab.local`

- **Primary Domain Controller (PDC):** A robust machine (physical or virtual) that runs Windows Server, designated to manage the domain `homelab.local`.
- **Secondary Domain Controller (SDC):** Optional but recommended for redundancy, can be a less powerful machine or virtual instance.

### Organizational Units (OUs) Structure

1. **CyberLab:**
   - Purpose: Contains resources specifically for cybersecurity research and testing.
   - Sub-OUs: `Testing Environments`, `Research`, `Tools`.

2. **HomeDevices:**
   - Purpose: Manages personal and home devices.
   - Sub-OUs: `Personal Laptops`, `Smart Home Devices`.

3. **NAS:**
   - Purpose: Organizes access to different NAS functionalities.
   - Sub-OUs: `Media`, `Personal Storage`, `Lab Data`.

4. **Users:**
   - Purpose: Manages all user accounts.
   - Sub-OUs: `Admins`, `Family`, `Guests`.

### Security Groups

- **LabAdmins:** Full access to CyberLab resources.
- **FamilyMembers:** Standard access to home devices, personal storage, and media.
- **MediaAccess:** Special access to media storage on the NAS.
- **Guests:** Restricted access to certain home devices and internet.

### User Accounts

- **Admin Account(s):** For managing AD and critical resources.
- **Family User Accounts:** Individual accounts for family members with appropriate access rights.
- **Guest Accounts:** Temporary accounts for visitors, with internet access and limited resource access.

### Network Configuration and Security

- **LAN/WLAN Segmentation:** Separate networks for `CyberLab` and `HomeDevices` to isolate traffic and enhance security.
- **Firewall and Access Rules:** Configure firewall rules to control traffic between segments and protect sensitive resources in the `CyberLab`.

### NAS Configuration

- **Media Storage:** Shared storage for family media like photos, videos, and music.
- **Personal Storage:** Private folders for each family member.
- **Lab Data:** Storage for cybersecurity research, tools, and data.

### GPOs for Security and Management

- **Password Policy:** Strong passwords for all users, with regular mandatory changes.
- **Update Policy:** Automatic updates for Windows devices to ensure security patches are applied.
- **Software Restrictions:** Limit software installation on `HomeDevices` to prevent malware.
