Hands-on work

My Projects

Pentesting, secure hosting and sensitive data: where theory from my Ethical Hacking studies meets practice.

Security projects

What I've built & tested

School project

Pentesting | Black-box

Context

A black-box assessment, meaning I started without any inside knowledge of the target, just like a real external attacker would. The goal was to find out how well the system held up and to report back in a way that a client could act on.

What I did

Mapped the target, investigated vulnerabilities and applied exploitation techniques to gain access, guided by the OWASP Top 10. Every step was documented, from reconnaissance to exploitation, and the findings were written up together with concrete security measures.

Security focus

Findings were rated with the Common Vulnerability Scoring System (CVSS) so that risks could be prioritised, and each one came with a countermeasure. Working within a clear scope and reporting honestly were part of the method.

School project

Hosting platform

Context

A team project to set up and configure a platform for managing and publishing (web) applications. The challenge was building something reliable that a group of users could depend on, not just something that worked once.

What I did

Set up and configured the platform together with my team, divided the work and kept each other up to date, so that applications could be deployed and opened up to users. This taught me a lot about system administration and about working towards a shared result.

Security focus

Implemented security measures to protect the platform against unauthorised access and common web vulnerabilities. Looking at the platform with a pentester's eye helped me harden it from the start instead of fixing problems afterwards.

Personal project

Medical sensor data

Context

A project I work on outside of school, using data coming from devices used by people with diabetes. It combines my interest in technology with something that has a real impact on people's daily lives.

What I did

Working on reading out the sensor data, processing it and adapting it into a form that is easier to use and understand. It is an ongoing project that lets me practise my scripting and data-handling skills.

Security focus

Health data is highly sensitive, so it is handled carefully and confidentially within the system. Privacy is a requirement from the beginning of the project, not an add-on.
