Projects

VMlab img

Virtual Home Lab Environment

I built a virtual home lab using VirtualBox to gain hands-on cybersecurity experience. The lab featured two VMs: one running Ubuntu Linux and the other Windows 11, with internal networks configured for communication. I enhanced my scripting skills in PowerShell and Bash while practicing malware analysis, endpoint security, and email security in a sandboxed environment. Using tools like CyberChef, Wireshark, tcpdump, Snort, and Splunk, I analyzed network traffic, detected anomalies, and managed logs. This project sharpened my technical skills, problem-solving abilities, and understanding of secure configurations and threat detection.

PCAP Data Analysis with Python

I developed Python scripts to filter and aggregate data from PCAP files, enhancing my understanding of network traffic analysis and cybersecurity workflows. Using libraries like Scapy and PyShark, I parsed PCAP files, identified key protocols, and extracted details like IP addresses, ports, and timestamps. The scripts summarized TCP conversations, top protocols, and other statistics, automating tasks that streamline packet analysis. This project deepened my understanding of networking concepts, improved my Python skills, and provided hands-on experience with real-world cybersecurity data. By automating data analysis, I demonstrated my ability to create tools for intrusion detection, threat hunting, and troubleshooting network environments.
