The true root causes of software security failures

In the 10 years since I launched my consulting/training venture, I've worked with thousands of software developers around the world. As you might expect, I've seen many software security failures. Given that experience, I'm often asked what I think are the biggest, baddest mistakes made in software today.

In response, I don't cite specific failures. That's what the OWASP Top-10 does. It and similar lists serve a purpose, but at heart they describe a set of symptoms of just a few, far bigger problems.

The two biggest problems I see -- focusing too much on functional specifications, and being overly trusting -- are in a sense two sides of the same coin. And it seems to me that pretty much the entire OWASP Top-10 list stems from these two things.

It's easy to understand why these problems are so persistent. The vast majority of software developers I've met and worked with are highly intelligent, motivated people. They often work in extremely stressful environments, with seemingly impossible deadlines to meet and a management team that seems to be uncompromising on those deadlines. With those pressures, it's not at all surprising that developers tend to focus most on the functionality of their products at the expense of other considerations, such as security. "What features does the customer need?" seems a more pressing question than "What can go wrong?" or "How can an attacker trick the software into misbehaving?"
