Sad State of Secure Software Maintenance

This is sad. No, it's not sad, it's sick. I'm looking for ideas and clear thinking about secure software maintenance. But I can't find anything beyond a couple of articles on Software Security in Legacy Systems by Craig Miller and Carl Weber at Cigital. I met Craig, he did some consulting work at a startup that I was running. He's a smart guy for sure. These papers offer some good advice to enterprises looking for where to start, how to get a handle on securing legacy systems and COTS packages. They are worth reading. But this is all I can find anywhere. And that's not good enough.

Most of us who make a career in software development will spend most of our careers maintaining and supporting software. If we're lucky, we will work on software that we had a hand in designing and writing; if we're not so lucky, software that we inherited from somebody else. Software that we don't understand and that we need to get control of.

Software maintenance is a risk management game. Understanding what's important to the business, trading off today's priorities with the long term view. Dealing with work that has to be done right now, what's needed for this customer, how fast can that change be done, what do we need to do to fix this bug. How much are we spending, and where can we save. And making sure that we're not sacrificing tomorrow: keeping the team together, keeping them focused and motivated, helping them moving forward. Keeping technical debt under control: taking on debt where it makes sense, paying it off when we can. And making sure that we're are always dealing with what's important: service levels to customers, reliability, security: protecting customer data.

There's more to secure software maintenance than running static analysis checks on the code and an occasional vulnerability scan and application pen test. And most teams aren't even doing this.

There's not enough smart people taking on the problems of how to manage software maintenance properly. And there's definitely not enough people thinking about software security and maintenance. Where to start, how much to spend, why, what's important, what the next steps should be, where do you get the most return. This has to change. It's too important to too many people. There's too much money being spent and wasted on doing a poor job at too many companies. There's too much at stake.
