Technical cybersecurity work requires more than familiarity with individual tools or operating systems. It also requires understanding how systems are designed, how vulnerabilities affect those systems, and how security concepts apply in operational environments. The artifacts below demonstrate my development across network infrastructure planning, vulnerability analysis, and the application of cybersecurity concepts in professional systems administration.
Network Infrastructure Case Analysis
Course: IT 315 – Introduction to Networking and Security
Artifact Type: Network Infrastructure Design Case Analysis
Artifact Description:
This case analysis required me to design network infrastructure for a multi-floor facility using physical layout requirements, cabling limitations, equipment needs, security considerations, and cost estimates. I calculated copper and fiber requirements, identified equipment and telecommunications-room locations, selected network infrastructure, and incorporated VLAN segmentation, firewall placement, backup power, and network resiliency into the proposed design.
Skills Demonstrated
- Network infrastructure planning
- Physical and logical network design
- VLAN segmentation and access-control considerations
- Equipment and resource planning
- Technical decision-making
MOVEit Zero-Day Exploit Analysis
Course: CS 462
Artifact Type: Cybersecurity Research Project
Artifact Description
This research project examined the 2023 MOVEit Transfer zero-day compromise and the CL0P ransomware group’s exploitation of CVE-2023-34362. I analyzed how the SQL injection vulnerability affected an internet-facing managed file-transfer application, the technologies and services involved in the compromise, the attacker’s use of web shells and data exfiltration, and the broader consequences for affected organizations. The project also examined mitigation measures such as patching, network segmentation, least privilege, web application firewalls, continuous monitoring, and third-party risk management.
Skills Demonstrated
- Vulnerability and exploit analysis
- Network and application security concepts
- Cyber incident research
- Mitigation and defensive-security analysis
- Third-party and supply-chain risk awareness
Cybersecurity Internship Final Reflection
Course: CYSE 368 – Cybersecurity Internship
Artifact Type: Professional Internship Reflection
Artifact Description
This final internship reflection examines how cybersecurity concepts applied to my existing systems-administration and operational responsibilities in a government-contracting environment. Across three 50-hour phases, I reflected on system validation, network and application troubleshooting, documentation, administrative processes, and coordination across technical and operational groups. The course encouraged me to evaluate work I had previously performed primarily from an operational perspective through concepts such as least privilege, network security, documentation as a security control, service continuity, risk management, and professional communication.
Skills Demonstrated
- Applied systems administration
- Network and application troubleshooting
- Security-focused operational analysis
- Technical documentation and process improvement
- Cross-functional professional communication
- Integration of academic cybersecurity concepts with professional practice
