Data Loss Prevention Implementation
Without proper preparation, the implementation of DLP policies may lead to unintended restrictions on user actions, such as copying files to USB drives or clipboard, causing disruption in workflow and productivity.

explanation for non-techies**

Microsoft is rolling out a new feature for Mac users within its Microsoft 365 suite that focuses on Data Loss Prevention (DLP). Think of DLP as a security guard for your digital files, ensuring that sensitive information doesn't leave your organization in ways it shouldn't. This feature is particularly focused on files stored on network shares and mapped drives, which are common ways businesses store and access shared files.

Imagine your company's network shares as a library where everyone can access and borrow books (or files, in this case). This new DLP feature acts like a vigilant librarian who ensures that no one takes out a book without proper authorization, especially if the book contains sensitive information. It can prevent actions like copying sensitive files to a USB drive or clipboard, which could lead to unauthorized data leaks.

The rollout will begin with a Public Preview in early February 2025, allowing organizations to test and configure these policies. By early March 2025, the feature will be generally available worldwide. This means businesses can start setting up rules that automatically protect sensitive files, just like having a set of guidelines for borrowing books from the library. If someone tries to perform an unauthorized action with a sensitive file, an alert will notify the relevant parties, much like an alarm going off when someone tries to sneak a book out without checking it out properly.

Moreover, organizations have the flexibility to configure exclusions. This is akin to having a special section in the library where certain books can be borrowed without the usual restrictions, perhaps because they are less sensitive or the borrower has special permissions.

To start using this feature, organizations can configure these DLP settings through the Microsoft Purview compliance portal. This portal acts as the control center where you can set up and manage these security measures, ensuring your organization's data remains safe and secure.
