Hoe veilig is online betalen?

Hij klikte op emails die zeer geloofwaardig leken en liet zien wat er, onzichtbaar voor de gebruiker, mogelijk was voor een hacker. De zaal begon ongemakkelijk op de stoelen te schuiven. Vervolgens kwam Michel van Eeten, hoogleraar bestuurskunde bij de faculteit Techniek, Bestuur en Management, met duizelingwekkende getallen. Minstens honderdvijftig miljoen computers over de hele wereld zijn gehackt. Van die privécomputers, die van u en van mij zouden kunnen zijn, wordt bijvoorbeeld spam verstuurd.

U leest het goed: uw computer kan gebruikt worden, onzichtbaar voor u, om spam te versturen. Dan merkt u bijvoorbeeld dat de computer wat trager is dan normaal. De zaal begon zich nu ook hoorbaar te roeren, helemaal toen Van Eeten zei dat die firewalls misschien 30 tot 40 procent van de aanvallen kunnen afweren. Maar het helpt niet echt, zo’n virusprogramma.

Wat zijn specifiek de gevaren bij internetbankieren? Hackers kunnen op slinkse wijze bedragen afschrijven. Van Eeten: “Terwijl u de acceptgiro van het energiebedrijf aan het intoetsen bent, kan de hacker het moment gebruiken om een groot bedrag van uw rekening af te schrijven. Deze afschrijving wordt niet vermeld in de reguliere staatjes, dat wordt gefilterd. U ziet er niets van. Tot u opeens merkt dat drieduizend euro is overgemaakt naar een rekening in de Bijlmer.” De Nederlandse Vereniging van Banken heeft tot nu toe geen inzicht willen geven in de cijfers over de omvang van internetfraude. Dit najaar komen ze met cijfers.

Hoewel er wel eens wat gebeurt, vindt Van Eeten internetbankieren relatief veilig. Bij creditcards bijvoorbeeld is het fraudebedrag vijf cent op iedere honderd euro. Dat noemt hij een aanvaardbaar risico.
Het is hem een doorn in het oog dat de banken de geleden schade niet willen vergoeden. Creditcardmaatschappijen doen dat wel. “Sommige mensen zijn door fraude met internetbankieren al hun spaargeld van bijvoorbeeld 20 duizend euro kwijtgeraakt. Banken moeten dat vergoeden.” In Amerika is dat al sinds 1979 zo geregeld. Waarom kan dat dan niet in Nederland?

Michael Samson van de Nederlandse Vereniging van Banken verweerde zich door te zeggen dat banken in de praktijk vrijwel altijd de schade vergoeden, maar dat ze dit recht niet garanderen. Dankzij Elsevierjournalist Simon Rozendaal brandde dit technologiedebat minstens zo hevig als het Carré-debat. Een mooie middag. 

De volgende Elsevier-technologiedebatten zijn op: 27 september: ‘De elektrische auto’ met Cees de Bont; 25 oktober: ‘De magie van nano’ met Cees Dekker en 29 november: ‘Bestrijding van terrorisme’ met Ben Ale.

“My room is quite new and has a flat-screen TV I never use but that looks really cool. I’ve heard about people hooking their TVs up to their computers to watch movies or play games, so I definitely see where my free time will go. The rest will go to parties, although not in our common room. Cool parties used to be held there, but unfortunately it was recently closed off; now it’s empty and looks like a soulless room. Otherwise I’ll make parties in my room! It has everything you need: IKEA furnishings, microwave, TV…. The bed is kind of small though, which forces me to practice my balancing act. Outside there’s a lawn that looks like a jungle. It used be just dirt, so at least it’s better now. There’s also a small pond, but it’s filthy. There’s also a canal, which three drunk Italians ended up in one night! I’ve already met my neighbors and we’re now organizing a party on the jungle lawn out front!

“From the 12th floor of my room in Roland Holstlaan I can see all of the Netherlands – this was my first impression. The second one was the silverfish – small insects that keep me company for dinner. So far it’s been amusing. The outside of the room is like heaven. Literally. Inside things aren’t so new. There’s some very old stuff, but I figure it’s classical decor. The one minute Albert Heijn trip is really cool though! I’m hooked already. Then there’s the canal. It has huge fish in it – really huge! You can also see birds fighting for bread crumbs. Fun stuff like that. Perhaps there’s a lack of neighborly interaction, due to the non-existent common room, but still I’m enjoying it, and I’ve met lots of cool people elsewhere on campus.”

“The room looks cool and cute, also clean, so in general fine, and it came equipped with kitchen stuff and other necessities. I don’t like the bathroom sharing part, though. Also in the kitchen people don’t clean after themselves. Perhaps we could invest more in cleaning. When I go into the kitchen I cannot cook or eat because it’s such a mess. The surroundings are nice. There’s a really nice pond just in front. Also, having an indoor bike shed is convenient. My neighbors are great. Many of them are classmates, which works nicely with doing projects and other fun stuff. I’ve also met lots of people that I had contact with through the Internet, so I’ve been able to put faces to names.”

“The room is very nice, lots of space and organized. But it seems inventory was lacking, because one lamp doesn’t work and I didn’t get any hangers. I do enjoy living alone, just not in the dark with no hangers. I’m fond of having my own bathroom and kitchen. I also like the view from the third floor, although higher up would be even better! On the other hand, I don’t like the view outsiders get into my room. I really like having a supermarket and tram stop close by. And my neighbors are amazing. I’ve already met Mexican and Greek neighbors who are really fun!

“My first impression was one of having everything we could possibly need on the first day. I arrived at my room after having some food at the airport, and getting there tired it was nice to find new sheets and a clean room, along with a complete student survival kit. I didn’t even have to open my suitcase that night! Next day I realized the room isn’t as small as I thought it would be: 14 square meters is really more than you think. My room is all a student could possibly ask for. The surroundings are also nice, but my neighbors even nicer! Friendly from the moment I arrived, they had a party and I was invited. This being my first time traveling outside India, it was so nice to feel welcomed and make friends from day one.”
Gargi Prasad, India, Computer Science, Roland Holstlaan

“I’m new to living alone. I expected a small room, and no matter how much I read about it before coming, I was pleasantly surprised when I saw my room. I cherish the thought of having a place of my own, and one that comes with a very comfortable armchair! Besides that, there’s no microwave, which I sort of miss, and the thin pillow I could definitely do without. From the 13th floor, things seem much more positive. My room has an amazing view! It gets really hot when it’s sunny, but I’ve been told not to worry about that too much here. But it did help me realize that the shades are broken. Also, the room was dirty when I arrived. There’s also no common room, so no place to meet people, but I do like the building’s location and proximity to the university.”
Bassem Zaarour, Lebanon, Management of Technology, Roland Holstlaan

“Very roomy! I didn’t expect this from what I’d heard about Europe. I arrived late at night, but immediately noticed the penthouse view. Later I met some nice neighbors. We talked about Roland Holstlaan’s convenient location. I also heard about things that had been reported to DUWO, minor problems like missing light bulbs. I think they have plenty of material now for ‘how many international students does it take to screw in a light bulb’ type jokes! The rent is a bit high, though. Inside the room is well-furnished, outside it’s decorated by Delft, which I already like very much! Such a quiet city; I joke with neighbors that it seems we’re the only people living in the city. For a change, we go to the laundry room, which is the closest thing we have to a common room. Our next party might even be in the laundry room! Bring your dirty clothes!”
Carlos Toro-Bermudez, Colombia, Management of Technology, Roland Holstlaan

“My first impression was good. The house is quite big and I have a 5th floor apartment. Great view! My room is spacious, comfortable. However, a dirty house meant lots of cleaning up initially. The furniture in the room is enough for a student, although the bed is maybe too small. The desks are really big, though, so I guess it’s about encouraging people to study more and sleep less! My neighborhood is great, everything close by, either walking or by bike. Building safety however seems like a potential concern. I like that my room is big and has a big window, so lots of light comes in, but I don’t like that it’s a rather old building, so it looks old. Also the kitchen is good, but there’s no oven – kind of weird as I was planning to use it to cook! I haven’t met many neighbors yet, but probably I will at local restaurants until we get an oven!”
