How I set up Active Directory using Server Core (No GUI)

1. Installed Windows Server Core on a VM (no GUI, only command line)

2. Used sconfig to configure:
-Server name
-Network settings
-Remote access

3. Assigned a static IP (192.168.1.1)

4. configured DNS which is very important for Domain controller

5. Installed Active Directory using PowerShell:
Command: Install-WindowsFeature AD-Domain-Services

6. Promoted server to Domain Controller:
ICommand: nstall-ADDSForest

7. Created structure:
-OUs (HR, IT, Admin)
- Users & Groups

lesson:
👉 DNS is EVERYTHING in Active Directory
If DNS fails, the domain becomes unreachable

This setup reflects real enterprise environments where GUI is minimal and control is done via CLI

Next: Joining client machines + applying GPOs

Module 3 @CiscoNetAcad Done☑️

Just wrapped up Wireless Networks and Mobile Connectivity. It's fascinating to see how the settings we use every day on our phones actually bridge into the wider network infrastructure

Digital Forensics Case Study: Hidden Data Inside an Image

As part of my cybersecurity learning journey, I conducted a hands-on digital forensics investigation on a suspicious image file.

What I did:

- Verified file type using Linux CLI tools
- Analyzed metadata with ExifTool
- Inspected image structure using ImageMagick
- Detected hidden content using Binwalk
- Extracted embedded files and analyzed their contents

Key Findings:

- The image appeared normal but contained an embedded ZIP archive
- The file had no meaningful metadata, indicating possible tampering
- Image analysis showed zero entropy (completely white), suggesting it was artificially created
- Hidden data was successfully extracted from within the file

Conclusion:
This case demonstrated how attackers can hide data inside seemingly harmless files to bypass detection systems.

Lesson Learned:
Never trust file extensions. Always verify, analyze, and investigate deeply.

Tools Used:
Linux CLI, ExifTool, Binwalk, Strings, ImageMagick

This is part of my journey toward becoming a cybersecurity professional.
