CAF – B3.d Mobile Data

This article provides additional information on how you can meet the requirement for the CAF control – B3.d Mobile Data.

Secure Handling of Mobile Devices and Media

  • Any device, equipment or removable media that may hold important data should be sanitised securely before reuse or disposal.
  • All such assets should be tracked within the organisation’s asset inventory so you can verify whether they contain data relevant to essential services.

Policies and Procedures

  • The organisation’s Records and Information Management Policy should define how mobile devices, equipment and media must be sanitised or destroyed.

  • Secure Asset Disposal Procedures should be followed to ensure appropriate handling throughout the asset lifecycle.

Secure Deletion and Media Sanitisation

  • Before any device or removable media is repurposed, transferred, decommissioned the organisation should apply Secure Deletion and Media Sanitisation processes using approved tools or certified third-party services, ensuring all important data is completely removed (Sanitise and Dispose of Media Securely).

Evidence of Secure Disposal

  • Disposal certificates or sanitisation records should be retained as evidence that data-bearing assets have been handled appropriately.

Preventing Data Recovery

  • These sanitisation procedures help ensure that important data cannot be recovered or accessed once mobile devices or media leave the organisation’s control.
