How do I stay calm during a major security breach?

You handle the everyday incidents well now. It is the major breach that overwhelms you, when the stakes jump, the whole company is watching, and everything seems to happen at once. That surge of overwhelm is not a sign you are not ready. It is what a big event does to anyone whose experience of them is still small.\nThe thing that steadies people in a crisis is not a calmer nature; it is a smaller focus. In a major breach you cannot hold the whole thing in your mind, and trying to is what floods you. So you shrink the problem. What is the single most important thing to do in the next ten minutes? Do that. Then the next. A big incident is just many small, doable steps stacked under pressure.\nSo prepare for the flood before it comes. Know your first moves cold, so that when panic rises your training answers first. Lean on your process and your team rather than trying to carry it alone; that is what they are for. And afterward, walk back through what happened calmly and learn from it, so the next major breach meets a version of you who has been here before. You are not failing under pressure. You are still building the nerve that only big events can teach.
