Description

This content presents an interactive mental model for Chief Information Security Officers (CISOs) to conceptualize their role across six dimensions: Governance, People Management, Strategy & Planning, Security Architecture, Security Engineering, and Security Operations. It is intended as a strategic and organizational framework for senior security practitioners to understand and manage their responsibilities effectively. The model is not a vulnerability or threat but a conceptual tool to aid CISOs in navigating their complex role.

The static version posted previously was well received. [Here](https://cybernative.uk/ciso-mental-model-interactive) is the interactive version with some enhancements. Might want to bookmark this.

The model is for senior practitioners, given the level of abstraction involved. It consists of six dimensions; Governance, People Management, Strategy & Planning, Security Architecture, Security Engineering, and Security Operations. These dimensions could be grouped into two sets, i.e. organisational focused along the top and the technical disciplines along the bottom. It's important to recognise this duality of the ciso role.

There are different ways the model can be applied. For example, a ciso entering a new organisation and having to rapidly establish a view of the environment they have inherited, in order to determine what adjustments might be required.

It could also be used as a workflow. For example, Strategy & Planning to define & proactively drive the ciso office agenda, the technical disciplines to design (arc), build & deploy (eng), and operate (ops) required controls. With Governance acting as the feedback loop and People ultimately required in delivering and sustaining the overall capability.

Does this resonate? Do you have a different way to think about the entirety of the ciso terrain?
