SharePoint Permissions Best Practices: Secure Your Data Post-Migration

Understanding SharePoint Permissions: Key Concepts

You’ve just completed your SharePoint migration—congratulations! But here’s the hard truth: mishandled permissions post-migration are the #1 cause of data breaches and compliance headaches. Imagine confidential files exposed to the wrong teams, or ex-employees still accessing sensitive data. Scary, right?

In this guide, we’ll walk you through SharePoint permissions best practices to lock down your data, avoid chaos, and ensure your migration efforts aren’t wasted. Plus, we’ll share how our SharePoint Migration Services team helps clients sidestep these pitfalls. Let’s dive in.

Before fixing permissions, you need to know the basics:

Permission Levels:

Read: View only.
Contribute: Edit and add items.
Full Control: Admin-level access (use sparingly!).
Custom: Mix and match (e.g., “Edit but not delete”)Example : Assign “Read” to contractors and “Contribute” to internal teams.

SharePoint Groups:

Pre-defined roles like Visitors, Members, and Owners.
Create custom groups (e.g., “Finance Team” or “External Partners”).

Inheritance:

Sub-sites and libraries usually inherit permissions from parent sites.
Break inheritance only when necessary (it’s a maintenance nightmare).

7 SharePoint Permissions Best Practices Post-Migration

1. Audit Permissions Before and After Migration

Problem: Migrated permissions often don’t match the source.
Solution:

Use the SharePoint Permissions Manager tool to scan for overly broad access.
Look for “Unique Permissions” flags in the Site Settings > Permissions menu.
Remove outdated users (e.g., ex-employees, old vendors).

2. Follow the Principle of Least Privilege

Problem: Users have unnecessary access.
Solution:

Start with zero access and grant permissions only as needed.
Use “Read” as the default for most users.

3. Use Groups, Never Individual Users

Problem: Assigning permissions to individuals creates chaos.
Solution:

Create groups like Marketing-Team-Edit or HR-View-Only.
Add/remove users via groups to simplify management.

4. Limit “Full Control” to Admins Only

Problem: Too many admins = higher breach risks.
Solution:

Restrict “Full Control” to 2-3 trusted admins.
Use SharePoint Permissions Manager tools to audit admin access.

5. Document Your Permission Structure

Problem: No one knows who has access to what.
Solution:

Create a permissions matrix (Google Sheets or Excel).
Track groups, access levels, and responsible owners.

6. Test Permissions Thoroughly

Problem: Broken access post-migration.
Solution:

Have test users (non-admins) validate access to files and sites.
Use Manage Access SharePoint features to simulate user roles.

7. Schedule Regular Permission Reviews

Problem: Permissions drift over time.
Solution:

Quarterly audits using SharePoint Permissions Manager tools.
Remove unused groups and update access as roles change.
