## Level

L1

## Profile Applicability

## Type

Manual

## Description

Shared drive file access should be restricted to that shared drive's members.

## Rationale

Preventing unauthorized users from access sensitive data is paramount in preventing unauthorized or unintentional information disclosures.

## Impact

Disabling this feature will prevent shared drive non-members from accessing content in shared drives where they are not a member.

6. Under `Shared drive creation`, ensure `Allow people who aren't shared drive members to be added to files` is `unchecked`

## Remediation

1. Log in to `https://admin.google.com` as an administrator
2. Select `Apps`
