With Microsoft OneDrive, you can securely share files with colleagues. However, it is important to understand the different Data Classification levels and acceptable ways to share P3 and P4 files.
Guidance for Data Classification Levels - P1 - P4 Data
Please read the UC Information Protection Standards to become familiar with the data classification levels:
| Link Type | P4 | P3 | P2 | P1 |
|---|---|---|---|---|
| Specific People (Direct Link) Internal User |
Acceptable | Acceptable | Acceptable | Acceptable |
| Specific People (Direct Link) External User |
Acceptable – Use good judgment | Acceptable – Use good judgment | Acceptable | Acceptable |
| People in "Your Organization" (Internal Link) |
Never use this link type with P4 | Acceptable – consider using the direct link if possible, for P3 | Acceptable | Acceptable |
| Anyone with the link (Open Link) |
Never use this link type with P4 | Never use this link type with P3 | Acceptable – Use expiration date when possible | Acceptable – Use expiration date when possible |
How to create links and share files.
The following important guidelines ensure you do not expose P3 – P4 data to external users:
- Please familiarize yourself with the different sharing options.
- Never create an “open link” (Anyone with the link) to a file or folder with P3 - P4 data.
Sharing Options:
When sharing a file or folder you are presented with the following options:
- Specific people (default link type) gives access only to the people you specify (internal or external users), although other people may already have access. If people forward the sharing invitation, only people who already have access to the item will be able to use the link. This is considered a “Direct Link” and the only acceptable way to share P3 – P4 data to external users.
- People in (Your Organization) gives anyone in your organization who has the link access to the file, whether they receive it directly from you or forwarded from someone else.
- People with existing access can be used by people who already have access to the document or folder. It does not change the permissions on the item. Use this if you just want to send a link to somebody who already has access.
- Anyone with the link gives access to anyone who receives this link, whether they receive it directly from you or forwarded from someone else. This may include people outside of your organization. This is considered an “Open Link”
If P3 – P4 data must be shared outside of the organization, use a “Direct Link” (Specific People). This will require a verification code sent to the intended recipient's email address if they are outside the organization.
