Abstract

The technology disclosed relates to method and system of monitoring and controlling exfiltration of enterprise data stored on the cloud computing service (CCS). The method and system includes using a cross-application monitor to detect a could service application programming interface (API) in use and a function or activity being performed via the CCS API. The method and system determines the function or activity by parsing a data stream based on the CCS API and identifies a content of the enterprise data subject to content control by the application of a content inspection rule data subject to content control. The method and system selects a security action being applied to the enterprise data to prevent exfiltration based on the classification of the inspected data and policies applicable to the content subject to content control.

Claims1

Dependent claims

A computer-implemented method, comprising:

detecting, with a cross-application monitor, a cloud computing service (CCS) application programming interface (API) in use;
detecting, with the cross-application monitor, a function or an activity being performed via the CCS API on an enterprise data;
parsing a data stream based on the CCS API and identifying content in the enterprise data being transmitted to the CCS;
determining the function or the activity being performed based on the parsing;
applying a content inspection rule to find strings and interrelated strings in the content that are subject to content control;
and
classifying, by the cross-application monitor, the content into a content type of a plurality of content types based on finding the strings and interrelated strings;
selecting a security action based on the content type into which the content was classified;
and
performing the security action on the enterprise data.
