Active in the security and computing science field since age 8. Experience in setting up security systems, international roll-out, education, auditing and pentesting. As one of the owners of the Dutch penetration testing firm Madison Gurkha, I have worked as head of HRM, COO, team manager, sales support, incident manager and more. As no other I can combine 25+ years of deep technical knowledge with soft skills. A passion of mine is to make technical concepts understandable, which is why I have spoken at many international conferences and have helped organise many of them as well.

After 15 years, I have ended my career at the foremost Dutch pentesting corporation and am open to new offers.

Lockpicking and IT Security

In this lecture, Walter Belgers will look at some security flaws in locks to see how they came about. Then, he shows us how similar mistakes are made in software development and deployment. In both cases, we have to deal with design flaws, implementation errors, zero day attacks, brute force attacks, user errors and more. Real life examples will be given and demonstrated. There are some interesting differences in how security is looked at in the hardware and the software world. Both groups can certainly learn each other.
