Junior Cybersecurity & QA Testing

Hi, I'm Ayhan. I graduated cum laude from Howest in Applied Computer Science, on the Cyber Security Professional track. Through my internship and SaaS projects, I’ve gained practical experience in testing applications, investigating issues, and documenting findings. I enjoy understanding how systems work and helping improve their security and reliability.

Open to junior SOC or QA testing roles in Belgium or remote.

Honeypot & Log Analysis

As part of a three-person team, I set up the logging and monitoring environment for our honeypot project. I built Kibana dashboards to explore web traffic and added ModSecurity to the web server.

My contribution

What the dashboards show

The saved views show HTTP responses, unusual requested paths, and user-agent strings associated with tools such as ffuf, curl, and Postman. They provide starting points for investigating traffic; a status code or user-agent string alone does not establish whether a request was malicious.
