Transfer Bundle

Discussion

The Crucible Concept of Operations establishes the Transfer Bundle as the transferable collection produced within a Connected Environment and imported into a Disconnected Environment.

A Transfer Bundle is a controlled collection of Artifacts, Dependencies, records, manifests, integrity information, and supporting Evidence assembled for transfer between environments.

A Transfer Bundle may contain:

Installation mediaSoftware packagesOperating-system update packagesMachine ImagesContainer ImagesProvider-specific contentInfrastructure source contentCompliance ArtifactsConfigurationRecordsManifestsIntegrity informationSupporting EvidenceA Dependency ManifestA Transfer Bundle facilitates controlled movement across an organizational, network, security, jurisdictional, or Air Gap boundary while preserving the identity, integrity, organization, and Provenance of its contents.

Within Crucible, a Transfer Bundle may contain captured content from a Dependency Store. A destination environment may import that content and use it to populate an internal software-package repository.

The same Transfer Bundle retains its identity through:

CreationTransferReceiptIntegrity verificationImportThe source phrases artifact export package and artifact import package describe the Transfer Bundle from the perspective of its creation or import. They do not identify separate transferable objects.

Source

Crucible Concept of Operations, Version 1.0, Sections 2.1, 3.3, and 3.4.

The Crucible Concept of Operations states that Crucible produces a compressed Transfer Bundle containing captured Dependencies and compliance findings within a connected enclave. The disconnected enclave imports the same bundle and uses its contents to populate an internal software-package repository.

The ConOps also identifies the enclave operator as the actor that imports transferred dependency and Evidence bundles into a Disconnected Environment.

This definition formalizes the ConOps concept without treating package and Transfer Bundle as separate names for the same architectural subject.

Note

A Transfer Bundle may use:

A compressed archiveRemovable mediaAn object-store representationA repository exportAnother controlled representationThe representation of a Transfer Bundle does not change its identity as the controlled collection transferred between environments.

Creating a Transfer Bundle does not by itself constitute Transfer Authorization.

Applicable review, approval, inspection, release, transfer, integrity-verification, and import processes govern movement across the applicable Transfer Boundary.

Transfer Bundle Integrity governs the completeness of the Transfer Bundle and the protection of its contents from unauthorized addition, removal, or modification.

A Transfer Bundle may contain software packages, but a Transfer Bundle is not itself a software package.

Example

Crucible assembles operating-system update packages, installation media, Container Images, infrastructure repositories, compliance Evidence, integrity values, and a Dependency Manifest into one Transfer Bundle for controlled transfer and import into an Air-Gapped Environment.
