DLP for Drive rules
Using data loss prevention (DLP), you can create and apply rules to control the content that users can share in Google Drive files outside the organization. DLP gives you control over what users can share, and prevents unintended exposure of sensitive information such as credit card numbers or identity numbers.
DLP rules trigger scans of files for sensitive content, and prevents users from sharing that content. Rules determine the nature of DLP incidents, and incidents trigger actions, such as the blocking of specified content.
You can allow controlled sharing for members of a domain, organizational unit, or group.
Summary of DLP flow:
- You define DLP rules. These rules define which content is sensitive and should be protected. DLP rules apply to both My Drive and Shared drives.
- DLP scans Drive contents for DLP rule violations that trigger DLP incidents.
- DLP enforces the rules you defined and violations trigger actions, such as alerts.
- You are alerted of DLP rule violations.
Use an audit-only rule to test new DLP rules
You can test DLP rules by creating rules that don't have an optional action, such as blocking or warning users. If these rules are triggered, data related to the incident is written to the Rules audit log. Go to Create DLP for Drive rules and custom content detectors, "Step 1. Plan your rules, Use audit-only rules to test rule results" for details.
DLP sample use cases
You can use DLP to:
- Audit the usage of sensitive content in Drive that your users may have already shared to gather information on sensitive files uploaded by users.
- Directly warn end users not to share sensitive content outside of the domain.
- Prevent sharing of sensitive data (such as a Social Security Number) with external users
- Alert administrators or others about policy violations or DLP incidents.
- Investigate details of an incident with information on the policy violation.
You might have used the original version of Drive DLP in the past. This table compares legacy DLP to the current DLP. This table helps you understand current features and behavior.
|Legacy Drive DLP||Current Drive DLP|
|Existing DLP product||DLP product with more features|
|DLP rules are found in the Admin console under Rules.||DLP rules are found in the Admin console under SecurityData protection.|
|To set up DLP policies, you have to be a super Administrator.||To set up DLP policies, there are specific administrative privileges for DLP rules and detectors. Managing DLP policies doesn't require permission to manage all Drive settings.|
|Match count is available only for predefined detectors.||Match count is available in all conditions that use:

||Detection thresholds with more granularity:
|Reports are limited to audit logs and Drive-related reports.||Reports include DLP Incident Management dashboards, available under SecurityDashboards.
Reports now include the shared recipients of the document.

Applications and file types scanned by DLP
Applications scanned include:
Comments in Docs, Sheets, Slides, and Drawings and comment email notification are not supported by DLP, and they are not scanned.
Forms and Sites are not supported with DLP at this time. Also, when you implement DLP, it prevents Forms file uploads.
Scanned file types
File types scanned for content include:
- Document file types: .doc, .docx, .html, .odp, .ods, .odt, .pdf, .ppt. .rtf, .wdp, .xls, .xlsx, .xml
- Image file types: .eps, .fif, .img_for_ocr, .ps
- Compressed file types: .7z, .bzip, .gzip, .rar, .tar, .zip

Video and audio file types are not scanned.
To create and set DLP rules and content detectors, you must be a super administrator or a delegated admin with these privileges:
- Organizational unit administrator privileges.
- Groups administrator privileges.
- View DLP rule and Manage DLP rule privileges. Note that you must enable both View and Manage permissions to have complete access for creating and editing rules. We recommend you create a custom role that has both privileges.
- View Metadata and Attributes privileges (required for the use of the investigation tool only): Security CenterInvestigation ToolRuleView Metadata and Attributes.
