Congratulations--you're a new CISO.

"I would say for any new CISO that's coming into an organization, it's really kind of important first to get to know the people who have been in place securing the environment. And sit down with them, and understand from them, where things stand from a security standpoint. It's important to understand the culture of the organization and really kind of step back a little bit and understand kind of what the risk tolerance is for the organization. And, you know, kind of based on that, you kind of understand where, you know, some of the potential gaps would be, kind of understand what the risk tolerance is. You can start to prioritize. At least in my case, having worked a lot with large enterprises, I think where a lot of people fall down is just doing things consistently across the board. You know, you have development environments. You have production environments. You have corporate IT environments. And you tend to have multiple teams working that. And things can get out of sync. So, you know, I think looking across the board there and just looking at kind of best practices that are occurring within each team and then trying to be able do that consistently and, you know, with rigor across the entire collection of IT systems is a good place to start."
