New one for me. CFO would like to me to make a chart of systems/networks and possible threats to get a better idea of the status of our environment.

I've never had to make anything like this before, and we would like to use it to make a plan for 2025 and 2026. The idea is to be able to show the Executives where the vulnerabilities lie, what projects we have in motion to plug the wholes, where we need more visibility or tools and see how much it will cost to achieve these goals.

I realize that there are many aspects to this, and I want to cover as much as possible in v1 of the chart. And some of the project may have the goal posts changed from now until a solution is implemented.

I was wondering if anyone has any templates we could use or suggestions of what to include, so that we cover as much as possible.
