To start with, Data Loss Prevention (DLP) helps to discover, monitor, and protect sensitive information across Microsoft 365 including Exchange Online, SharePoint Online, OneDrive for Business, and Microsoft Teams. The DLP comes with features to identify sensitive information based on predefined patterns, provide real-time policy tips, and generate detailed reports of DLP policy use and compliance.
DLP Permissions
There are three levels of permissions in DLP: Organization Management, Compliance Data Administrator, and Security Reader. These provide varying levels of control over the DLP environment.
- Organization Management: These individuals have full control over the environment and all types of permissions like Read, Write, Execute, Delete, etc.
- Compliance Data Administrator: These administrators have restricted access. They typically have read and write permissions, but don’t have rights to delete.
- Security Reader: These are typically members of your IT department who need to view the DLP policies and related data, but don’t need to modify any settings. They have Read permission.
Here is a comparative view of these permissions:
| Permission Level | Read | Write | Execute | Delete |
|---|---|---|---|---|
| Organization Management | Yes | Yes | Yes | Yes |
| Compliance Data Administrator | Yes | Yes | Yes | No |
| Security Reader | Yes | No | No | No |
Configuring Permissions
To configure permissions for DLP in Microsoft 365, you need to follow these steps:
- Sign in to Microsoft 365 Compliance Center.
- Navigate to “Permissions” in the left-hand navigation pane.
- Choose “Data loss prevention”.
- Add the users to whom you want to provide permissions and assign them appropriately.
It is recommended to provide minimum permissions based on the principle of least privilege. The fewer people that have access to sensitive information, and the fewer privileges they have, the better your security stance.
Conclusion
Configuring permissions for DLP is an essential part of data security. To do it effectively, you should understand the roles and responsibilities of each individual, and assign permissions based on their need to have access. Remember, DLP permissions should be part of a broader information protection and compliance framework. Always ensure that these configurations align with your organizational policies and regulatory compliance needs.
This information should provide a good start for those looking to gain a better understanding of configuring permissions for DLP in preparation for the SC-400 Microsoft Information Protection Administrator exam.
