Cyber Security SOC analyst
Summary
Passionate and detail-oriented Cyber Security enthusiast with strong analytical and problem-solving skills. Empathic listener with excellent communication, organizational, and management abilities. Dedicated to making a positive impact, eager to continuously learn, and approaching challenges with an entrepreneurial mindset.
Beyond my tech and legal skills in Cyber Security, I'm fascinated by the human side of it. I enjoy unravelling what motivates people, understanding their actions, and crafting solutions that meet genuine needs. I find joy in roles that allow me to integrate my tech expertise with this human perspective, creating solutions that truly make a difference.
Experience
SOC analyst
Analyst in the Security Operations Center (SOC) of the Public Prosecutor's Office / District Attorney of the Netherlands.
As a SOC Analyst, I handle the essentials—monitoring, investigating, and responding to security incidents. On top of that, I dive into tasks typically owned by SOC Engineers, like writing and fine-tuning detection rules. I also take on more strategic roles usually associated with Security Consultants or Architects, such as assessing the SOC’s maturity and driving initiatives to elevate its effectiveness and resilience. So it’s a role that lets me do a little bit of everything happening in the SOC, keeping things interesting and always challenging!
SOC analyst
SOC analyst in the Security Operations Center of Northwave. In this role, I handled a constant flow of security alerts every day, all while staying within tight SLAs to make sure incidents were resolved quickly and accurately. I got to work with several different SIEM platforms, which helped me get really comfortable with detecting and responding to a wide range of security threats. It was a fast-paced environment where I learned how to balance speed with precision, and it really deepened my understanding of security tools and processes..
Intern BLUE - Detection Quality & Stack
This 5-month Cyber Security internship is part of my master's program at Radboud University and Eindhoven University of Technology.
Owner and administrator
Owner and administrator of a Dutch ethical hackers community (with nearly 8,000 registered members and over 100,000 posts). Founded in June 2012 by me.
Owner
When I was in high school, I supported people in my city solving their computer problems during the weekends.
Co-Founder and Board Member, Head of Communications
With four others, I founded a residents association to represent and defend the interests of approximately 70 residents. Within the association, I was responsible for the communication with external parties, such as STW Nederland and the municipality of Leiden.
Education
Cyber Security (Master's Degree)
Topics in the 18 courses of this master include cryptography, security in software, testing techniques, network security, privacy, security in organizations and tech laws (such as the GDPR). Some of the courses were taught at Eindhoven University of Technology. My thesis was about fingerprinting mobile users in (4G/LTE) telecommunication networks using their installed apps. In my internship, I created a scoring system for Northwave to be able to assign a score to their detection rules in the SOC.
Information Security Technology
Some courses from the Master's program from Radboud University were taught at Eindhoven University of Technology. This was a collaboration between the two universities, formerly known as the TRU/e Cyber Security program. The courses I followed were called Principles of Data Protection, Cryptology, Applied Cryptography, Hackers Hut and Verification of Security Protocols.
Volunteering
Guest speaker
During De Avond van Cleveringa, I was invited to give a talk on the significance of hackers and my personal journey in exploring the fine line between what is permissible and what is not.
