I started my security (post-sysadmin) career heavily focused on security policy frameworks. It took me down many roads, but everything always came back to a few simple notions, such as that policies were a means of articulating security direction, that you had to prescriptively articulate desired behaviors, and that the more detail you could put into the guidance (such as in standards, baselines, and guidelines), the better off the organization would be. Except, of course, that in the real world nobody ever took time to read the more detailed documents, Ops and Dev teams really didn't like being told how to do their jobs, and, at the end of the day, I was frequently reminded that publishing a policy document didn't translate to implementation.
Subsequently, I've spent the past 10+ years thinking about better ways to tackle policies, eventually reaching the point where I believe "less is more" and that anything written and published in a place and format that isn't "work as usual" will rarely, if ever, get implemented without a lot of downward force applied. I've seen both good and bad policy frameworks within organizations. Often they cycle around between good and bad. Someone will build a nice policy framework, it'll get implemented in a number of key places, and then it will languish from neglect and inadequate upkeep until it's irrelevant and ignored. This is not a recipe for lasting success.
Thinking about it further this week, it occurred to me that part of the problem is thinking in the old "compliance" mindset. Policies are really to blame for driving us down the checkbox-compliance path. Sure, we can easily stand back and try to dictate rules, but without the adequate authority to enforce them, and without the resources needed to continually update them, they're doomed to obsolescence. Instead, we need to move to that "security as code" mentality and find ways to directly codify requirements in ways that are naturally adapted and maintained.
