I’ve had some interesting experiences with two companies recently that I’d like to share. We all do business with companies online: we buy from them, we schedule appointments, we put in support requests, and so on. Today, I very seldom use the mail, and don’t shop in person very often. How these businesses treat customer security is interesting. Some places are very technically savvy and have robust, secure online transactions. Being realistic, though, I know that my dentist’s office does not employ a full-time sysadmin. They buy an off-the-shelf customer care solution and hire someone to install it on their website. Sometimes that’s good, sometimes that’s bad…
First was with my mechanic. I like my mechanic – they’ve saved me quite a bit in the past. But they’re notoriously bad about answering the phone. However, they are surprisingly up to date for such a shop. They have a website which allows you to schedule your appointments online, no need to call. That’s great!
Necessarily, this means you need to have an account on the website. Okay, this makes sense: they track your name, contact information, kind of car you have, and the car’s maintenance history including mileage. While nothing there is particularly incriminating or dangerous unto itself, it’s not the sort of information I’d like to have broadcast to the world, either. So it’s good that this information is kept in an individual account not available to others.
However, I admit that I couldn’t recall my password for that account. No problem, I put in the username and requested a password reset. The automated tool asked for my email, which I gave, and it sent me a new password.
Do you see the problem? It wasn’t asking me for my email address to confirm that I should be the recipient of that password. It was asking in order to know where to send the new password. There was no confirmation process; it just sent the password to the address I’d provided.
And that’s how I got into someone else’s account. My first clue was that I don’t own a Mitsubishi. No harm done – I didn’t even get the person’s contact information, I simply figured out my correct account name (I was off by one letter) and logged in properly. But that’s no security at all.
On the flip side, I wanted to get support for a piece of electronics I bought recently. I was looking for a driver for it, and couldn’t find anything, so I thought I’d go ahead and contact their support team. In theory this should be a straightforward enough thing. In practice, not so much. You have to open an account with the manufacturer. For which you need to own an actual product. Now, that’s a bit of an issue – what if I was looking at buying a product and wanted to know beforehand if the driver existed? But I already owned this item. So I went to open the account (and set up to handle all the forthcoming spam, I’m sure.) Part of the process involves saying just which device you own. Now, the item I had wasn’t listed. I made the best match, a similar item with a different model number. Shouldn’t make a difference, right?
Oh, but it does. The item I selected is listed, for some reason, as out of warranty. And on that I was frustrated – I cannot make inquiries about an item which is out of warranty.
I’m sure this system reduces needless support requests. In this case it also prevented a real request; I won’t be buying this company’s products in the future.
What can we learn here? Well, two companies, two lessons.
In the first case, make sure your system applies basic security. My mechanic has relatively trivial information on me, sure, but they have some information, and they’re not securing it well enough. The idea of a confirmation before resetting a password has been “best practice” for longer than I can remember. If you’re going to bother having individual user accounts, there’s no excuse to not treat them with at least some security.
In the second case, your security shouldn’t get in the way of your business. Sure it’d be nice to be able to make sure every single contact was authenticated and properly routed, but if you have any reason to deal with the public that’s just not going to happen.
The overall lesson is that even if you’re a small company, your security has to match your needs. An off-the-shelf solution without any thought behind its application won’t do you any good.
