Cybersecurity Student | Vulnerability Management | Defensive Operations | AI in Cyber
Cybersecurity student with hands-on professional experience in vulnerability management and email security. I've worked in a real enterprise security environment at Marist University, where I used Tenable Nessus, Microsoft Defender, and Wireshark to reduce organizational risk and triage alerts daily. My technical interests span penetration testing, malware analysis, AI-driven threat detection, and web application security.
Documented an unknown production network through physical and logical assessment of a multi-router environment. Executed Nmap OS detection across 6 subnets and reconstructed full network topology across Windows Server 2019, Quagga routers, and pfSense firewalls — achieving 100% documentation accuracy in Zenmap.
Tools: Nmap, Zenmap, Windows Server 2019, pfSense, Quagga
Hardened a Linux system by implementing 25 CIS Benchmark controls, including deactivating insecure services (FTP, Telnet, SNMP, RSH, NIS), locking root login, and patching critical vulnerabilities via apt. Produced detailed configuration checklists to verify security state.
Tools: Ubuntu Linux, CIS Benchmarks, apt, Bash
Implemented least privilege principles, user/group management, and PAM-based password policy enforcement on an Ubuntu Linux system.
Tools: Ubuntu Linux, PAM, Bash
Secured data at rest using LUKS full-disk encryption and strict file permissions, then validated a complete backup and recovery workflow.
Tools: Ubuntu Linux, LUKS, rsync
Identified active network attacks and authentication vulnerabilities by analyzing live traffic. Detected ARP poisoning and IP conflicts via gratuitous ARP filtering and extracted plaintext RIPv2 credentials to demonstrate passive interception risks.
Tools: Wireshark, TCP/IP, ARP, RIPv2
