The Palo Alto Networks white paper presents a five-step methodology for simplifying Zero Trust implementation. Steps include defining the protect surface (data, apps, assets, services), mapping transaction flows to understand system interactions, building a Zero Trust architecture with segmentation gateways, creating granular policies using the Kipling Method (who, what, when, where, why, how), and continuously monitoring and maintaining the network. This iterative approach enhances security without disrupting existing infrastructure, allowing organizations to incrementally adopt Zero Trust across networks, endpoints, and cloud environments.
