Abstract

A computing device receives a training data set that includes a plurality of positive examples of sensitive data and a plurality of negative examples of sensitive data via a user interface. The computing device analyzes the training data set using machine learning to generate a machine learning-based detection (MLD) profile that can be used to classify new data as sensitive data or as non-sensitive data. The computing device displays a quality metric for the MLD profile in the user interface.

Claims

computing the quality metric, wherein the quality metric includes at least one of a false positive rating, a false negative rating or a memory utilization rating.

3. The method of claim 2, further comprising:

receiving a user selection of a memory allocation via the user interface before analyzing the training data set, wherein the memory utilization rating for the categorization data complies with the memory allocation.

4. The method of claim 2, further comprising:

enabling a deploy operation if the false positive rating is within a false positive threshold and the false negative rating is within a false negative threshold;

receiving a user request to perform the deploy operation via the user interface; and

in response to receiving the user request, adding the MLD profile to a data loss prevention (DLP) policy of a DLP system.

5. The method of claim 2, further comprising:

identifying in the user interface at least one of data that caused false positives and data that caused false negatives from the training data set.

6. The method of claim 1, further comprising:

receiving categorization information for the positive examples of sensitive data and for the negative examples of sensitive data; and

identifying in the user interface categories of data to add to the training data set to improve the quality metric.

7. The method of claim 1, further comprising:

modifying the training data set in response to user input if the quality metric fails to meet a quality threshold;

analyzing the modified training data set to retrain the MLD profile; and

displaying a new quality metric for the MLD profile in the user interface.

8. The method of claim 1, wherein the training data set was collected by a data loss prevention (DLP) policy of a DLP system, the plurality of negative examples of sensitive data comprising documents that were misclassified as sensitive documents by the DLP policy, the method further comprising:

deploying the MLD profile to the DLP policy.

9. The method of claim 1, further comprising:

receiving a selection of a sensitivity threshold via the user interface for the MLD profile; and

controlling a sensitivity threshold setting for the MLD profile based on the selection.
