Hydroficient Externship via Extern
Hydroficient Externship via ExternAs a Computer Science student, I tackle tech challenges and support others. I’ve built labs in Active Directory, ServiceNow, and Cisco while sharpening my cybersecurity skills.
I’m securing IoT systems, from threat modelling a hotel’s water system to hardening MQTT pipelines, for organisations using connected devices. I’m driven by solving problems and protecting people.

Build, hack, and defend real IoT infrastructure, then hand your security playbook to an actual company. You’ll launch realistic cyberattacks, from spoofing and replay attacks to unauthorized shutoffs, and implement defenses like TLS and mTLS.
4-VLAN network design and troubleshooting – designed, configured and troubleshot a 4-VLAN network, including inter-VLAN routing, DHCP, DNS and ACLs. Aim: Design a segmented business network featuring centralised services, separating IT, Finance, HR and Server infrastructure into 4 VLANs. Outcomes: C
IT incident management – logged and resolved 5 user incidents end-to-end. Aim: Practise end-to-end incident management in a Windows domain environment, from user issue through to resolution. Outcomes: Troubleshot each issue using Active Directory and Windows administration, and wrote 1 knowledge art
Windows Server 2025 administration – deployed and administered a Windows Server 2025 domain with 4 user accounts and 1 Windows 11 Enterprise workstation, including account provisioning and lockout recovery. Aim: Simulate a 4-department business domain (IT, HR, Finance, Executive) to practise identit
As a Computer Science student, I tackle tech challenges and support others. I’ve built labs in Active Directory, ServiceNow, and Cisco while sharpening my cybersecurity skills.
From Computer Science at secondary school to an Erasmus+ internship in Lisbon and a D*D*D* BTEC in IT, I’ve always loved learning by doing. While studying Computer Science at City St George’s, I’ve built Active Directory, ServiceNow and Cisco labs and I’m now securing IoT systems through Extern. I’m driven by helping people and aim to build my career in IT support and security.

The work inspected an operational smart-building IoT deployment and documented device roles, network topology, and communication patterns. The project analyzed attack surfaces across device-to-cloud and device-to-device channels, then executed hands-on experiments to validate vulnerabilities and defenses.

I produced a documented threat model for the smart-building IoT system, including a PDF report and a visual model card that prioritized identified risks.
During the externship I mapped system components, applied STRIDE to identify threats, prioritized risks, and produced a documented threat model with a PDF report and a visual model card as deliverables.
