Enterprise SharePoint deployments contain sensitive data, from intellectual property to compliance impacting information (PII, PCI and PHI). Users are not always aware of what data is classified as sensitive and they can unknowingly create information security and compliance issues. Microsoft SharePoint 2016 provides new Data Loss Prevention (DLP) capabilities that allow us to find and protect sensitive information in SharePoint and OneDrive for business. These capabilities alert users to when they are working with sensitive information, and they help you work with document owners to reduce the risk to your organization and remain compliant with industry regulations. In this session, Demoing Live Protection, Antonio Maio will show you how to deploy and configure DLP in SharePoint 2016 to support your security and compliance objectives.

9. Data Loss Prevention (DLP)
Goals

• Payment Credit Industry Data (PCI, PCI DSS)

11. Data Loss Prevention in SharePoint 2016
Available through…
• Improved eDiscovery Site Collection
• New Compliance Policy Center Site Collection

12. SharePoint 2016
DLP Policies for eDiscovery
eDiscovery Center
• Create & run DLP Queries to identity sensitive data
• Save Queries
• Export Data

13. SharePoint 2016
DLP Policies for Compliance
Compliance Center
• Create DLP Policies to monitor and enforce protection of
sensitive information
• Provide administrator notification (via email)

• Must have a healthy search index and crawl
• Configure out-going email (recommended)
• Turn on Usage reports (recommended)
• Create the eDiscovery or Compliance Center site collections (mandatory– both not needed)
• eDiscovery – for DLP Queries to identify where sensitive data exists

• Assign permissions to Compliance team through the
Site Collection Members group (recommended)

15. Creating the Compliance Center

29. DEMONSTRATION

30. Important Technical Notes
• If its not in the search index DLP policies will not be enforced
• Consider your crawl schedule
• 4 Timer Jobs used to enforce policies
• Policies not enforced on new documents until search crawl and timer jobs complete
• Timeliness of policy enforcement depends on priority of policy template
• Can take up to 24 hours
• Cannot enforce policies on list items – only documents (not yet proven)

31. Final Thoughts
• Data Loss Prevention just one critical part of securing
sensitive data
• Identifying sensitive data, monitoring its usage and enforcing policies
• DLP requires regular management of policies – refine to avoid noise of false positives
• SharePoint 2016 DLP is a great start!
• Start learning and testing SharePoint 2016 DLP Today
• Critical to have healthy search index
• Test policies in Staging before deploying to Prod
