Series context. Part 2 of the Forensics and Futures 2026 series examines how cloud storage systems reshape digital evidence, expert testimony, and evidentiary risk. As organizations rely on object storage, managed backups, and provider-controlled retention, courts increasingly scrutinize how cloud-stored evidence is authenticated, preserved, and explained by experts.

Cloud Storage Forensics Is an Expert Testimony Problem
Cloud storage is often discussed as a technical or security challenge. In litigation and regulatory proceedings, it is fundamentally a challenge of expert testimony.
Unlike traditional media, cloud storage provides evidence:
Is abstracted from physical hardware
Collected using different mechanisms and tools that do not perform the same way as traditional preservation tools.
It is often collected from a live environment, making it difficult, if not impossible, to validate the entire collection (“image”) using hashes.
May contain metadata that is impacted by the Cloud storage services and may not be consistent with standard file metadata from an isolated physical source.
As a result, expert witnesses are no longer testifying solely about what the evidence shows, but about:
How the storage system functions
How the extraction process was accomplished
What the examiner could and could not control
Where evidentiary uncertainty may exist
