kevin townsend drew my attention to this post on the google online security blog about responsible disclosure (should you read the post, pay special attention to the list of authors - if you've been paying attention to the disclosure debate lately you'll recognize one of the names). it discusses the fact that responsible disclosure sometimes fails to provide adequate motivation for software vendors to fix their code and how that actually puts users in danger because it means the vulnerabilities in question won't get fixed.
unfortunately the security folks over at google fall into pretty much the same trap that a lot of the security community falls into - the trap of binary thinking (i'm sure there's a loftier term but this will do). when we talk about disclosure many people only consider two main alternatives: full disclosure and responsible disclosure. in reality, however, there are additional alternatives between those two and even some beyond those two.
unless you're quite new to the security field or have been living under a rock these past couple of years you probably have heard of partial disclosure - dan kaminski famously used it for the DNS vulnerability discovered back in 2008. whatever your opinion of partial disclosure might be, it clearly highlights the fact that there are more than 2 options when it comes to disclosure. in fact, partial disclosure opens up an entire range of options depending on how much information you disclose. the number of options for partial disclosure is limited only by one's own imagination and creativity.
what that means in practice is that it's actually possible to apply a strategy of 'graduated response' if you find a vendor is being too stubborn. it's not necessary to jump directly from responsible disclosure to full disclosure, you can gradually apply increasing amounts of pressure while at the same time not arming malicious attackers with new digital weapons.
unfortunately the disclosure debate has become religious. this is a big problem because it prevents people from considering alternatives. it polarizes opposing sides (which is odd when you consider that the true opposite of full disclosure is not responsible disclosure but actually non-disclosure) and creates an environment where people exhibit what emerson might well describe as 'a foolish consistency'. people need to get over themselves and their dogmas. disclosure (like many other things) is just a tool, and it's important to use the right tool for the job. sometimes the right tool may well be full disclosure, other times it may well be responsible disclosure, and still other times it might be something in between. the google folks are right to put the focus on protecting the users, but focus alone won't really help if they can't figure out how to use the right tool for the job (and one of them, at least, appears unable to).
