Every Policy in the Policy Catalog is represented in two ways:
As structured Rego code, which offers developers a developer-friendly way to view Policy as code supporting the full Policy development life cycle.
As a visual representation in the Policy Map, which offers a graphical view of the Authorization question that the policy represents: "WHO (Dynamic Groups) can do WHAT (Assets & Actions) and WHEN (Conditions)?".
