Cybersecurity Techniques and Operations

Course & Experience Overview

CYSE 301 focused on combining C programming with hands-on cybersecurity operations. The course introduced core programming concepts before applying them to real-world security tasks like network analysis, intrusion detection, and penetration testing. A key experience that stood out was analyzing network traffic using Wireshark while connecting those observations to how systems process data at a low level. During this lab, I examined packet captures to identify suspicious behavior, trace communication patterns, and understand protocol interactions. This activity took place in a structured lab setting but closely resembled real SOC work. It helped bridge the gap between programming and operational cybersecurity by showing how vulnerabilities and attacks appear both in code and in live network traffic.

Skills, Values, and Career Connection

This experience strengthened my analytical thinking, attention to detail, and technical problem-solving skills. While working through packet analysis and C programming assignments, I had to carefully interpret data and troubleshoot issues, reinforcing persistence and precision. It also improved my ability to connect theory to practice, which is critical in cybersecurity. These skills align with my professional goal of becoming a Cyber Auditor, where evaluating systems and identifying risks requires both technical depth and critical thinking. Additionally, the experience built on skills I use in my current incident response role, especially in monitoring and analyzing network activity. Moving forward, I will apply this knowledge to better understand system vulnerabilities and enhance my ability to assess and secure complex environments.

Artifacts & Evidence

The course produced a range of artifacts that demonstrate both programming and cybersecurity skills. These include C programming assignments (such as hexadecimal conversion, string manipulation, and a reverse Polish expression evaluator), as well as hands-on lab outputs like Wireshark packet analysis, TCPdump traces, firewall configurations in pfSense, and penetration testing results. From these, I would highlight my Wireshark analysis report, a C programming project, and firewall configuration screenshots. These artifacts best represent my ability to apply technical knowledge in practical scenarios. They show not only my understanding of programming concepts but also my capability to analyze network traffic, identify threats, and implement security controls in a realistic environment.

Artifact Explanation

One of the most valuable artifacts is my Wireshark traffic analysis report. In this assignment, I analyzed a packet capture file to identify abnormal or potentially malicious activity. I examined different protocols, followed TCP streams, and looked for indicators such as unusual ports or suspicious data patterns. This artifact is important because it reflects a real-world cybersecurity task commonly performed in SOC environments. To help an audience understand its significance, I would explain the purpose of the lab, the tools used, and the conclusions I reached. Including this artifact on my website demonstrates my ability to perform detailed network analysis and provides clear evidence of my hands-on experience with industry-relevant tools and techniques.
