====== Offline Transfer ======

[[dido:99_annexes:annex-b-terms-and-definitions:start|Go to Terms and Definitions]]

===== Discussion =====

Offline Transfer moves information or [[dido:99_annexes:annex-b-terms-and-definitions:a:artifact|Artifacts]] between environments without using a direct network connection between the source and destination environments.

Offline Transfer may use:

  * Removable storage media
  * An intermediary transfer device
  * A physically transported storage system
  * An approved transfer appliance
  * A controlled staging environment
  * A manually operated import and export process

Offline Transfer commonly applies when one or both environments are:

  * [[dido:99_annexes:annex-b-terms-and-definitions:d:disconnected_environment|Disconnected Environments]]
  * [[dido:99_annexes:annex-b-terms-and-definitions:a:air-gapped_environment|Air-Gapped Environments]]
  * Subject to restricted network connectivity
  * Separated by a security or administrative boundary

An Offline Transfer may include activities such as:

  * Selecting the transfer content
  * Creating a transfer bundle
  * Authorizing the transfer
  * Recording the source and destination
  * Verifying bundle integrity
  * Scanning for prohibited or malicious content
  * Physically transporting the transfer medium
  * Importing the transfer bundle
  * Recording the transfer result

Offline Transfer differs from online transfer:

  * Offline Transfer does not use a direct network connection between the source and destination environments
  * Online transfer transmits content through a network path connecting the participating environments

The use of removable media alone does not establish a controlled Offline Transfer. Applicable authorization, integrity, inspection, handling, and accountability controls determine whether the transfer satisfies its requirements.

===== Definition =====

//transfer of information or artifacts between environments without a direct network connection between the source and destination environments//

===== Note =====

Offline does not necessarily mean that every device participating in the transfer lacks network connectivity. The defining characteristic is the absence of a direct network transfer path between the source and destination environments for the transfer being performed.

An Offline Transfer may cross one or more [[dido:99_annexes:annex-b-terms-and-definitions:t:transfer_boundary|Transfer Boundaries]].

Applicable requirements may govern:

  * Transfer Authorization
  * Permitted content
  * Permitted media
  * Encryption
  * Integrity verification
  * Malware scanning
  * Chain of custody
  * Import and export records
  * Media sanitization
  * Retention and disposal

===== Example =====

An operator exports an approved transfer bundle from a Connected Environment to encrypted removable media, physically carries the media to an Air-Gapped Environment, verifies the bundle integrity, and imports the bundle through an authorized process.
