Programmers Who Don’t Understand Security Are Poor at Security

A university study confirmed the obvious: if you pay a random bunch of freelance programmers a small amount of money to write security software, they’re not going to do a very good job at it.

In an experiment that involved 43 programmers hired via the platform, University of Bonn academics have discovered that developers tend to take the easy way out and write code that stores user passwords in an unsafe manner.

For their study, the German academics asked a group of 260 Java programmers to write a user registration system for a fake social network.

Of the 260 developers, only 43 took up the job, which involved using technologies such as Java, JSF, Hibernate, and PostgreSQL to create the user registration component.

Of the 43, academics paid half of the group with €100, and the other half with €200, to determine if higher pay made a difference in the implementation of password security features.

Further, they divided the developer group a second time, prompting half of the developers to store passwords in a secure manner, and leaving the other half to store passwords in their preferred method — hence forming four quarters of developers paid €100 and prompted to use a secure password storage method (P100), developers paid €200 and prompted to use a secure password storage method (P200), devs paid €100 but not prompted for password security (N100), and those paid €200 but not prompted for password security (N200).

I don’t know why anyone would expect this group of people to implement a good secure password system. Look at how they were hired. Look at the scope of the project. Look at what they were paid. I’m sure they grabbed the first thing they found on GitHub that did the job.

I’m not very impressed with the study or its conclusions.
