The security community has this widely-understood reputation for self-destruction. This is not to say that other communities of professionals don't have this issue, but I don't know if the negative impact potential is as great. Clearly I'm not an expert in all fields, so I'll just call this a hunch based on unscientific gut feeling.
What I do see, though, much like with the efforts of the "I am the Cavalry" movement which has sent an open letter via Change.org to the auto industry, is resentment and dissent without much backing. In an industry which still has more questions than answers - and it gets worse every day - when someone stands up with a possible effort towards pushing a solution you quickly become a lightning rod for nay-sayers. Why is that?
One of my colleagues who is the veteran CISO has a potential answer - which for the record I'm uncomfortable with. He surmises that the collective "we"(as in security community) aren't actually interested in solving problems because the real solutions require "soft skills like personality" and business savvy in addition to technical accumen. It turns out that taking the time to understand the problem, and attempt to solve it (or at least move the ball forward) is very hard. With the plethora of security problems in nearly everything that has electricity flowing to it, it's near-trivial to find bugs. Some of these bugs are severe, some of them are the same 'ol, same 'ol SQL injection and buffer overflows which we identified over a decade ago but still haven't solved. So finding problems isn't rocket science - actually presenting real, workable solutions is the trick. This is just my humble opinion based on my time in the enterprise and consulting in.
I once worked for a CISO who told his team that he didn't want to hear about more problems until we had a proposed solution. Furthermore, I'm all for constructive criticism to help contribute to the solution - but don't attack the person or the proposed solution just to do it. Don't be that person.
I think it may have been Jeff Moss that I heard say it - "Put up or shut up"... so give me your solution idea, or stop whining things are broken.
