SharePoint sharing link security

Question

How to ensure the confidential when sharing the sensitive information in SharePoint ?

My context is:

I have 5 types of information and want to create sharing link for internal and external user. But for the external I want the expired link for the specific time also make sure they cant access the other type of information.

Is it possible to do it in CSOM environment ?

Hi @Titus Tolbert (Sr. Dev Operation, Hoka corp)

Thank you for posting your question in the Microsoft Q&A forum. 

From your description, my suggestion is creating separated links for internal and external users.

For external, you can use this method Web.CreateAnonymousLinkWithExpiration method 

For internal, you can use either

Web.ShareObject Method (Microsoft.SharePoint.Client) | Microsoft Learn or

Web.CreateOrganizationSharingLink Method (Microsoft.SharePoint.Client) | Microsoft Learn

You can read at CSOM SPT for more details how to use it:

[MS-CSOMSPT]: CreateOrganizationSharingLink | Microsoft Learn

[MS-CSOMSPT]: ShareObject | Microsoft Learn

[MS-CSOMSPT]: CreateAnonymousLinkWithExpiration | Microsoft Learn

I hope this information helps.
