SharePoint Sharing and Access Controls

First, when it comes to protected data, we need to take a moment to make sure that SharePoint specific data controls are enabled. Although we will not go into use cases or configuration on these, you should be aware that where to find these controls.

Sharing

Go to sharepoint.com. Click on Polices - Sharing

On the right side, you will see sliders that control content sharing.

Below that you will see More External Sharing Settings.

Below that, you will see controls around Link Sharing and other seetings.

Access Controls

Go to sharepoint.com. Click on Polices – Access Controls

On the right side, you will see various options for controlling access to your SharePoint data. Navigate these controls and investigation what options are available to your organization.

Move to the next section where we will address the Purview Specific workloads with your SharePoint, Teams, and OneDrive platform.

Mapping Purview to Collaboration

Here we will map the Lifecycle of the data (Create -> Use -> Retain -> Delete) of files and data to OneDrive, SharePoint Sites and Team Sites.

When looking at the Information Lifecycle, it is important to understand which Purview tools map to which collaboration activities within that Information Lifecycle. Here is a high-level map.

As this is a bit of an eye chart, we will look at each stage of the Information Lifecycle individually.

Please note that Use & Retain are placed together as these tend to be interchangeable.
