DLP Scanning

Updated 1 month ago by admin

The Cloud Application Security product supports enhanced Data Loss Prevention (DLP) when operating in API Mode. DLP can be used to detect potential data leakage and data exfiltration, by scanning the content of files uploaded and modified within connected third-party cloud storage services. The DLP Scanning feature has a number of predefined dictionaries for ease of use, and also supports custom keyword patterns.

To utilise DLP Scanning, you will first need to connect at least one of the supported cloud storage apps by configuring an API integration.
DLP Scanning requires access to file content. If DLP Scanning is enabled, the CASB product will download any newly uploaded or modified files, scan them, and highlight any DLP violations in the Cloud Activity (API) report. Once scanning is complete, the file is deleted. The file is downloaded using the credentials the administrator user that you used as part of the API integration process. This will appear as an event within the third-party cloud storage service.

To enable DLP Scanning visit your USS Dashboard, and click ProductsCloud Application SecurityDLP Scanning.

Ensure that the DLP Scanning: toggle is set to to reveal the available DLP Scanning options.
