TL;DR: Data access governance focuses on who can reach sensitive files, why that access exists, and whether it is still justified, addressing permission sprawl, over-privilege, and audit gaps in cloud and file-share environments, according to Imprivata. The governance problem is not just identity control but proving data-level need, ownership, and recertification across changing access patterns.

Questions worth separating out
Q: How should security teams govern access to sensitive files beyond IAM roles?
A: Security teams should use data access governance to validate whether a role-based entitlement still makes sense at the file, folder, or library level.
Q: Why do copied groups and inherited permissions create so much risk?
A: Copied groups and inherited permissions accumulate access that no one actively reapproved.
Q: How do you know if recertification is actually working for data access?
A: Recertification is working when reviews remove stale access, produce a named data owner for each sensitive repository, and leave behind clear justification for what remains.
Practitioner guidance
- Inventory sensitive data repositories first Build a complete map of file shares, cloud libraries, NAS locations, and collaboration spaces that hold sensitive information.
- Tie every entitlement to a business owner Require a named data owner for each sensitive repository and each high-risk access path.
- Use recertification to remove stale access Run recurring reviews on project folders, shared drives, and regulated data sets.
