Always exciting in infosec?

I have a couple of Tweet searches I follow. One of them tracks tweets with the keyword “infosec”. This morning I woke up with this tweet in the list:

now an excel 0day. woohoo. it’s always exciting in infosec.

This tweet is very typical: it’s always about hacks, attacks in the wild … I personally find that very disappointing, the above tweet even has something morbid.

Although talking about specific vulnerabilities is important, it is a lot more important to talk about avoiding those vulnerabilities in the first place. I see extended articles explaining in great detail how they hacked Adobe PDF documents, web applications or something commonly used. They do this with such pride and amusement that I get this feeling they are sorry they can’t use them in the wild. It almost looks like as if the only thing that differentiates the real authors of malware from these infosec people, is the sense of ethics the second group has. Ethics that stand in the way of making money with the vulnerability found.

As I said, a detailed knowledge of vulnerabilities is very important. But talking about how to do better and avoiding them in the first place, that gives a lot more return on investment in the long term. What could authors of (faulty) software have done to make a better product? What specific design patterns, code patterns … would have avoided the vulnerability? Wich steps in their quality control methods are missing that could have prevented the vulnerability? Every article on a vulnerability is useless for me if it doesn’t mention advice to avoid the vulnerability tomorrow. Luckily there are many authors that do, but sadly also many that don’t.

I don’t think we got this far in constructing buildings by detailing every single collapse of a building without doing any lessons learned. We also try to find out how we can avoid disasters for any future building: tools, methods, procedures and guidelines are  updated as a consequence. That is what makes us move forward. That is what allows us to do bigger while at the same time become better.

Acting on today’s vulnerabilities will not protect us tomorrow. Today we need to work so we can prevent tomorrow’s vulnerabilities and help us control the overall risks.
