The Kipling Method, which refers to asking 'Who, What, When, Where, Why, and How,' is particularly relevant in understanding and mapping the detailed transaction flows of a network. In Step 2 of the Zero Trust methodology, mapping transaction flows requires answering these questions to ensure a deep understanding of how data moves through the network, who initiates it, what data is involved, where it is going, when it is happening, why it is occurring, and how it is being transported. This step is crucial for implementing effective Zero Trust policies later on.
