Sven and the Art of Computer Maintenance is the personal site of Sven Kiljan. Here I publish what interests me either professionally or personally.
The best way to describe my profession is as a blend of information science and information security. Currently I am employed at a small Dutch startup known as RedTeam Cyber Security. Redteam is a company specialized in information security services for small and medium-sized enterprises, as well as providing security expertise for larger companies. Through Redteam I am currently working at Achmea, the largest insurance company in the Netherlands.
Previously I worked for CCV, a company that provides digital payment services for brick and mortar shops and webshops. These services include payments with credit cards (Mastercard, Visa, American Express), and both international and local online payment systems (PayPal, SEPA Credit Transfer, iDEAL, Bancontact).
Before all of that I was a PhD candidate at Open University of the Netherlands in the Kennisprogramma Veiligheid Digitaal Betalingsverkeer (Research Program on Safety and Security of Online Banking), a research program hosted by an academical partnership between NHL University of Applied Sciences and Politieacademie known as Lectoraat Cybersafety. My daily work was conducted at Radboud University in Nijmegen where I worked in the Digital Security research group of the Faculty of Science under supervision of my promoter, Marko van Eekelen.
My research consisted of exploring, expanding and evaluating usable security in online banking. For exploration, I examined 80 banks worldwide on which user authentication methods they employed for home and mobile banking, as well as on the applied communications security measures. A proposal was suggested by me to expand the existing options that banks have to authenticate transactions initiated by users, termed What You Enter Is What You Sign. This is a more secure and usable alternative to the well known What You See Is What You Sign transaction authorization scheme. Also, I proposed two methods to compare and evaluate existing and new online banking authentication methods. My PhD thesis can be found here. I received my doctor's degree in June 2017.
My e-mail address can be derived from: <first name>@<last name>.org
For those who do not have any experience reading syntaxes:
- Start by entering my first name.
- Add an @ sign to the end.
- Add my last name to the end.
- Finally, add a period and the letters o, r and g to the end (in that order).
