Identifies import and transport operations for integration packages and artifacts in SAP Cloud Integration. Packages contain integration flows, mappings, scripts, and other artifacts that can be imported from external sources or transported between tenants. Unauthorized package operations could indicate: - Supply chain attack through malicious package import - Lateral movement between environments via artifact transport - Introduction of backdoors or rogue integration logic

Stages and Predicates

Let binding: packageActions used in Stage 4

let packageActions = dynamic(["Package_Import_Started", "Package_Import_Completed", "Package_Transport_Started", "Package_Transport_Completed", "Artifact_Transport_Started", "Artifact_Transport_Completed"]);

Stage 1: source

Stage 2: where

Stage 3: extend (3 consecutive steps)

| extend action = tostring(parsedData.action),

Stage 4: where
