Ensure the SharePoint default sharing link permission is set

Why This Matters

Default sharing link permissions in SharePoint determine how files and folders are shared by users. If the default is set to "Edit" instead of "View", users may inadvertently grant write access to resources that only need read access. This increases the risk of unauthorized data modification or deletion, violating the principle of least privilege and potentially exposing sensitive information.

What Aether365 Checks

Aether365 verifies that your SharePoint default sharing link permission is set to "View" in the Microsoft 365 tenant configuration. This check appears in your Aether365 dashboard under microsoft-365 checks as part of the CIS Microsoft 365 Foundations Benchmark compliance monitoring.
