How this typically unfolds

Anonymized scenario walkthrough

A mid sized company discovers an internal data breach. The IT department initiates a forensic investigation using Google Workspace, Microsoft 365, and Dropbox. They begin by accessing Google Vault to preserve emails and documents related to the breach. Microsoft Purview is used to manage and review sensitive data that might have been accessed. Audit logs from Dropbox are analyzed to track file access and sharing activities. The investigation reveals unauthorized access by an employee who shared confidential files externally. The company's legal team uses the preserved data and logs to support disciplinary actions and potential legal proceedings. Throughout the process, compliance with the ECPA and CFAA is ensured, and the company's data retention policies are reviewed to prevent future incidents.

When this applies

This guidance applies when businesses utilize cloud platforms like Google Workspace, Microsoft 365, and Dropbox and need to conduct forensic investigations. It is relevant for organizations that must comply with data retention laws and require tools for eDiscovery and data governance. The guidance is applicable when audit logs and data preservation are necessary for legal or compliance reasons.

When this does not apply

This guidance does not apply when businesses do not use cloud services or when the data involved is not stored or managed within Google Workspace, Microsoft 365, or Dropbox. It is also not applicable if the organization does not have legal or compliance obligations related to data retention or if the investigation does not require forensic analysis of cloud-stored data.
