 Introduction:

The digital landscape is constantly evolving, and with it, the sophistication of cyber threats. To stay ahead in this ever-changing arena, I embarked on an ambitious project: setting up a Microsoft Azure Hacking Lab. This lab was designed to simulate an enterprise network with vulnerable machines, offering a practical environment for honing my cybersecurity skills. In this blog, I'll walk you through my journey of creating this virtual battleground.

1. Laying the Groundwork: Azure Virtual Machines

The first step was to establish the core of my hacking lab. I chose Microsoft Azure for its robust and flexible infrastructure.

- Deploying the Domain Controller: I started by deploying a domain controller on Windows Server 2022. This acted as the backbone of my network, managing all domain-joined machines.

- Adding Windows Servers: To add complexity, I deployed two Windows Server 2019 machines. These servers were crucial for simulating real-world enterprise environments.

- Integrating Windows 11 VMs: For a more contemporary touch, I included two Windows 11 VMs, joining them to the domain to mimic a typical organizational setup.

2. Simulating Real-World Networks: Multiple VNETS

To realistically replicate an enterprise network, I created multiple Virtual Networks (VNETS) within the Azure Resource Group. This setup allowed me to:

- Mimic Multiple Subnets: By segmenting the network into different subnets, I could simulate various departments or branches of an organization.

- Test Network Security: This configuration was ideal for experimenting with network security measures and understanding how breaches can occur in different network segments.

3. The Art of Vulnerability: Creating Targets

A hacking lab is incomplete without vulnerable targets. I carefully configured the machines to have specific vulnerabilities, enabling me to practice various attack techniques and penetration testing strategies.

4. Monitoring and Alerts: Utilizing Azure Monitor

To keep tabs on the lab's performance and security, I utilized Azure Monitor. This tool was instrumental in:

- Tracking Performance Metrics: I could monitor the performance of each VM, ensuring the lab ran smoothly and efficiently.

- Setting Up Alerts: By creating alerts, I was immediately notified of any unusual activities or potential security breaches, mimicking real-world security operations center (SOC) alerts.

5. Learning and Adapting: Continuous Improvement

Setting up the lab was just the beginning. The real value came from constantly tweaking and improving the setup. I learned to:

- Adapt to Challenges: Each step presented unique challenges, from configuring VMs to setting up networking, pushing me to find creative solutions.

- Stay Updated: Keeping the lab updated with the latest vulnerabilities and patches mirrored the dynamic nature of real-world cybersecurity.

Conclusion:

Building a Microsoft Azure Hacking Lab was an enriching experience. It was not just about setting up a network of machines; it was about creating a realistic environment to test, learn, and improve cybersecurity skills. This lab serves as a personal training ground, where I can continuously challenge myself and stay ahead in the ever-evolving world of cybersecurity.

Final Thought:

For anyone looking to enhance their cybersecurity expertise, I highly recommend embarking on a similar journey. The hands-on experience and the insights gained are invaluable in understanding and combatting the complexities of cyber threats.

 Introduction:

Embarking on a journey through the cloud can be both exhilarating and daunting. My recent adventure involved setting up VPN servers across three major cloud platforms: Azure, Linode, and AWS. Each step of the way, from creating virtual machines (VMs) to configuring OpenVPN servers, was a learning experience filled with unique challenges and triumphs. In this blog, I'll share my experiences, hoping to enlighten others embarking on similar cloud-based endeavors.

1. The First Stop: Azure

Azure's sophisticated interface initially seemed intimidating, but its well-documented resources guided me through.
