Security is closer to product management and marketing than engineering. It's a narrative and the mirror image of product and marketing, where instead of creating something people want based on desire, it's managing the things people explicitly don't want. When organizations don't have product management, they have anti-product management, which is security. We could say, "There is no Anti-Product Division."
Specifically on accountability, I bootstrapped a security product that replaced 6-week+ risk assessment consultant spreadsheets with 20mins of product manager/eng conversation. It shifted the accountability "left" as it were.
When I pitched it to some banks, one of the lead security guys took me aside and said something to the effect of, "You don't get it. we don't want to find risk ourselves, we pay the people to tell us what the risks and solutions are because they are someone else. It doesn't matter what they say we should do, the real risk is transferred to their E&O insurance as soon as they tell us anything. By showing us the risks, your product doesn't help us manage risk, it obligates us to do build features to mitigate and get rid of it."
I was enlightened. Manage means to get value from. The decade I had spent doing security and privacy risk assessments and advocating for accountability for risk was as a dancing monkey.
I worked in GRC space for a while, which is where I finally realized the things I wrote above. Our product intended to give CISOs greater visibility into threats and their impacts, making it easy to engage in probabilistic forecasting to prioritize mitigations. Working on designing and building it made me see the field from the perspective of our customers, and from their POV, cyber-threats are all denominated in dollars, mitigating threats boils down to not having to pay corresponding dollars, and that it's often more effective to ensure someone else pays than to address the underlying technological or social vulnerability.
