Data Classification in Microsoft 365

Data protection is probably the central area of concern regarding system security. The proliferation of online systems means tension between data privacy and usability. The key to a usable but safe data environment is knowing what level of protection needs to be applied to different data, that is, how to classify data. In the past, this has been a predominantly manual and subjective exercise. As data volumes have expanded exponentially, there is a need for automated data classification systems. This lesson looks at the data classification technologies available through the Microsoft 365 compliance portal.
