Cybersecurity intern at WakeMed who documented DMZ traffic flows and connected Duo applications to the SIEM using APIs.

Message

At WakeMed, I’ve contributed across the Information Security Department, including its Firewall, IAM, Threat Intelligence, and SOC teams. I documented an internal and external DMZ NAT IP list to make traffic flows easier to visualize.

With IAM staff, I helped add applications to Duo authentication systems and connect them to the SIEM using APIs. I also audited admin permissions, role groups, and servers in Active Directory to reduce privilege creep.

I worked with Threat Intelligence teams on a visual representation of traffic flows through internal systems, including feeds from Trend Vision One, Rapid7 TIP, and Palo Alto. I also observed and responded to suspected phishing emails and participated in a company-wide phishing awareness campaign.

Outside work, I’m studying penetration testing through OffSec’s PEN-200 course, TryHackMe, and HackTheBox challenges as I prepare for the OSCP certification. Earlier, as a CAD Engineer Intern at DCS (Data Spectrum Corporation), I worked on PET/SPECT brain phantoms in Fusion360 and modified milling-path CAD files to reduce material waste.
