6 Practical Cybersecurity Projects to Improve Your Skills

Hands-on experience is essential in cybersecurity. Whether you're experienced or just starting out, practical projects can improve your skills and make you more attractive to employers.

Here are seven practical cybersecurity projects covering important areas like firewalls, VPNs, honeypots, penetration testing, web application security, SIEM, and malware analysis.

Each project provides real-world experience and helps build a solid portfolio.

Let's explore these projects to boost your cybersecurity skills!

1. Building a Virtual Private Network (VPN)

Setting up a VPN server teaches you about secure remote access and encryption.

VPNs are commonly used by businesses to provide secure remote access for employees, partners, and suppliers. They also protect individuals using public networks at cafes, hotels, and other locations.

Creating a VPN server helps you understand secure communication, which is essential for protecting data over untrusted networks – a skill highly valued by companies with remote employees.

This project is ideal for understanding how VPNs create secure tunnels, encrypt data, and ensure privacy.

You learn how to configure and manage VPN connections, implement encryption protocols, and secure remote access.

Skills Gained

• Secure Communications
• Encryption Techniques
• Network Security Management
• Remote Access Configuration

Deployment Options

• Single Board Computers like Raspberry Pi
• Travel Routers like GL.iNET 1300 Slate Plus
• Virtual Machine
• Cloud Instance
• Old Desktop or Laptop

Example Projects

• OpenVPN
• WireGuard

2. Creating a Honeypot

Deploying a honeypot helps you learn about detecting and analyzing potential attacks.

By setting up a honeypot, you gain experience with threat monitoring and analysis, which is crucial for understanding attacker behavior.

This project lets you understand real threats by attracting, logging, and studying attack attempts on a simulated system.

Learning Benefits

You gain practical experience in setting up honeypot environments, monitoring attacks, and analyzing threat patterns.

Skills Gained

• Threat Detection & Intelligence
• Malware Analysis
• Intrusion Detection
• Incident Investigation

Deployment Options

• Single Board Computers like Raspberry Pi
• Virtual Machine
• Cloud Instance
• Old Desktop or Laptop

For better security, deploy the honeypot on a cloud instance or Virtual Private Server (VPS). This keeps your home or work network secure and prevents exposure if the honeypot is compromised.

Example Projects

• Cowrie
• Dionaea
• DShield
• T-Pot

3. Simulate a Penetration Test

Setting up a Kali Linux environment and testing against vulnerable machines in your home lab helps you learn ethical hacking.

Simulating penetration tests provides hands-on experience with tools and techniques used by pentesters, which is valuable for identifying and fixing vulnerabilities.

This project is ideal for identifying and exploiting vulnerabilities in a controlled environment, building your own lab, and improving your ethical hacking skills.

Learning Benefits

You gain experience in ethical hacking, vulnerability assessment, and exploitation techniques.

Skills Gained

• Penetration Testing
• Vulnerability Assessment
• Ethical Hacking Tools and Techniques
• Virtualization

Deployment Options

• Virtual Machine
• Cloud Instance
• Old Desktop or Laptop

Example Projects

Download vulnerable machines from: - Kioptrix 1 - Metasploitable2 - Metasploitable3

By downloading virtual images and setting up a virtual home lab using VirtualBox or VMWare, you also learn virtualization and operating system configuration skills.

4. Practice Web App Security Testing

Deploying a vulnerable web application helps you learn about finding and exploiting web vulnerabilities.

Practicing with intentionally insecure web applications gives you hands-on experience with tools and techniques used in web application security testing.

This project helps you find and exploit web application vulnerabilities, improving your web security skills.

Learning Benefits

You develop practical knowledge in identifying and exploiting common web vulnerabilities and using testing tools like Burp Suite and OWASP ZAP.

Skills Gained

• Web Application Security
• Vulnerability Identification
• Exploitation Techniques
• Security Testing Tools

Deployment Options

• Virtual Machine
• Cloud Instance
• Old Desktop or Laptop

Example Projects

• DVWA (Damn Vulnerable Web Application)
• bWAPP (Buggy Web Application)
• JuiceShop (OWASP JuiceShop)

All three projects are excellent OWASP initiatives. JuiceShop comes with a detailed guide on the vulnerabilities it contains and how to exploit them.

5. Setup a SIEM Server

A SIEM (Security Information and Event Management) server is essential for collecting and analyzing security data to detect and respond to threats.

Setting up a SIEM server provides hands-on experience in log management, threat detection, and incident response, which is crucial for modern security operations and Security Operations Centers (SOC).

This project helps you learn to collect, analyze, and respond to security data, improving your threat detection and incident response skills.

Learning Benefits

You gain practical knowledge in log analysis, threat intelligence, and security event management.

Skills Gained

• Log Management
• Threat Detection
• Threat Intelligence
• Incident Response

Deployment Options

• Virtual Machine
• Cloud Instance
• Old Desktop or Laptop

Example Projects

• Elastic Stack (ELK)
• Splunk Free
• Graylog
• Security Onion

SIEM setups can be complex. Start with a free or community version to get familiar with the basics. Mastering one SIEM tool and its query language will make it easier to work with others, as they share similar core concepts.

6. Conducting Malware Analysis

Creating a malware analysis environment allows you to safely examine and understand malicious software.

Setting up an isolated environment for analyzing malware provides hands-on experience with tools and techniques used to study malware behavior, an essential skill for cybersecurity professionals.

This project helps you safely analyze and understand malware behavior, improving your reverse engineering and threat intelligence skills.

Learning Benefits

You gain practical experience in safely analyzing malware, understanding its behavior, and identifying signs of compromise.

Skills Gained

• Malware Analysis
• Reverse Engineering
• Behavioral Analysis
• Threat Intelligence

Deployment Options

• Virtual Machine
• Cloud Instance
• Old Desktop or Laptop

Example Projects

Use these tools to set up your analysis environment: - Cuckoo Sandbox - REMnux - FLARE VM

Alternatively, you can analyze samples from online malware repositories such as: - VirusTotal - MalwareBazaar

⚠️ Be careful when dealing with malware projects and samples. Never use your work or personal laptop, even in a VM! Always use a dedicated machine to avoid risking your data.

Conclusion

I strongly encourage you to try these projects to improve your cybersecurity skills. Whether you're already working in the field or trying to get started, these projects can significantly boost your abilities and strengthen your resume.

They help solve the common problem of needing experience to get a job and needing a job to gain experience.
