NTFS Permissions and RBAC for a Teams Use Case
This video demonstrates how to configure NTFS permissions for a use case where all team data is maintained by individual departments, all team members can create and read all team data, team members can modify only their own data, and there is no inter-team data access.
Security group membership is designed around Role Based Access Control (RBAC).
If you are new at NTFS, I recommend you review the NTFS Security Basics at • NTFS Security Basics and NTFS Permission Inheritance at • NTFS Permission Inheritance beforehand.
