This project simulates an enterprise infrastructure environment using:
- VirtualBox
- Windows Server
- Windows Client
- Active Directory
- Group-Based File Permissions
- Network Isolation
It demonstrates practical implementation of:
- Identity management
- Domain authentication
- File share security
- Permission layering (Share vs NTFS)
- Network troubleshooting
- Deploy a Domain Controller
- Configure Active Directory
- Create users and security groups
- Implement secure file sharing
- Join a client machine to the domain
- Perform intentional break testing

- Domain authenticated
C:\SharedDocs
SharedDocs
- Removed default “Everyone”
- Granted access to
FileShare-Access
- Granted Modify access to
FileShare-Access
From Client:
ping 192.168.50.10
Test File Share Access
\\192.168.50.10\SharedDocsExpected Result:
Authentication successful
File creation allowed
File modification allowed
File deletion allowed
📸 Screenshot – Successful File Access
These scenarios simulate real-world infrastructure failures.
🔴 Scenario 1 – Permission Removal
Action:
Remove user from FileShare-Access group
Goal:
Observe authorization failure
📸 Screenshot – Broken Permission State
🔴 Scenario 2 – DNS Failure
Action:
Change client DNS to 8.8.8.8
Test:
Domain authentication
File access
Goal:
Demonstrate DNS dependency in AD
🔴 Scenario 3 – Network Failure
Action:
Disable client network adapter
Or modify network settings
Goal:
Observe connectivity failure behavior
📌 Skills Demonstrated
