What advice do you have for someone starting out in this field?
The work, as identified in most textbooks on cyber leadership, boils down to the triple constraints of cost, schedule and scope, or, how much money are you willing to spend, how much time do you have, and what do you want? None of these dimensions is independent of the other two and people want to think that a change can simply be absorbed into a project. The cyber leader must remind people, even when they are agreeing to a change, that there is always an impact to the other dimensions.
