SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Sensitive data such as PII, PHI, and PCI can leave an organization through everyday endpoint activities like USB copies, cloud uploads, webmail pastes, and printing. This Skill guides the deployment of endpoint Data Loss Prevention controls that detect and block unauthorized data movement while meeting GDPR, HIPAA, and PCI DSS requirements.

Core Features & Use Cases

  • Sensitive Information Type Definition: Configure built-in and custom SITs (credit cards, SSNs, employee IDs) with regex patterns, confidence levels, and corroborating keywords.
  • Policy Creation & Channel Coverage: Build Microsoft Purview or Symantec DLP policies covering USB, cloud upload, network share, print, clipboard, unallowed browsers, and Remote Desktop copy.
  • Phased Enforcement & Monitoring: Deploy in audit mode, tune false positives via Activity Explorer, then enforce blocking while tracking override rates and incident response.
  • Use Case: A security team seeds a test file containing five credit card numbers, then attempts USB copy, personal OneDrive upload, and webmail paste from a test endpoint to verify each channel produces a block event with the matched SIT.

Quick Start

Ask the assistant to walk you through creating a Microsoft Purview endpoint DLP policy that blocks credit card data from being copied to USB drives and personal cloud storage.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I deploy endpoint DLP with Microsoft Purview?▼

Endpoint DLP deployment starts by defining Sensitive Information Types, then creating a DLP policy scoped to Devices with conditions and block or audit actions per activity. Onboard endpoints via Intune or SCCM, run the policy in test mode with notifications for two to four weeks, then switch to enforcement.

What endpoint activities can DLP policies monitor and block?▼

Endpoint DLP can audit or block cloud uploads, copies to removable media and network shares, printing, clipboard copies, access by unallowed browsers or apps, and copies to Remote Desktop sessions. Each activity is configured independently as audit, block with override, or block.

Should DLP policies run in audit mode before enforcement?▼

Yes, deploy in test mode with notifications first so Activity Explorer shows audit events without blocking users. Use this period to identify false positives, tune SIT confidence levels and keywords, and add exclusions before turning the policy on.

Why does DLP miss encrypted or password-protected files?▼

Content inspection cannot read password-protected ZIPs, nested archives, or images without OCR, so those files bypass detection. Define an explicit handling rule such as block-on-unscannable rather than allowing them through silently.

When should I use network DLP instead of endpoint DLP?▼

Endpoint DLP covers data movement on the device itself, while network DLP uses inline proxies for traffic inspection and CASB covers cloud-only scenarios. This Skill explicitly excludes network DLP and cloud-only DLP deployments.
