A resource database which stores structured data describing resources from a diverse array of origins (e.g., an application or cloud environment) is built and maintained to support querying, policy enforcement, and remediation of resources from any origin. Structured data representing resources are obtained from any origin for insertion and categorized based on their type and/or origin. Resources within a category have a shared set of potential object paths as defined by the hierarchical tree structure of their structured data. Resources may be correlated across categories based on having values at different object paths in common. Queries and rules/policies can thus reference resources of any category and also resources across different categories based on correlations between the resources, thereby extending rule/policy enforcement and incident remediation across multiple different origins of resources.
