CIS Control 3.13: Deploy a Data Loss Prevention Solution
Data Loss Prevention (DLP) is your automated sentinel against unauthorized data exfiltration. CIS Control 3.13 requires deploying host-based DLP tools to discover, monitor, and protect sensitive data wherever it lives—on-premises, remote, or in transit. For SMBs, this means preventing costly breaches before they happen.
What this means
CIS Control 3.13 mandates implementing automated DLP technology to identify all sensitive data stored, processed, or transmitted across your enterprise—including devices, servers, and remote locations. The control focuses on both discovery (building an accurate inventory of sensitive data) and prevention (blocking unauthorized movement of that data). This applies to all assets under your control, whether managed internally or through third-party service providers.
How to comply
- 1.Select and deploy a host-based DLP solution that covers all enterprise assets and operating systems
- 2.Configure DLP policies to detect and classify sensitive data types (PII, financial records, intellectual property, credentials)
- 3.Scan all enterprise assets—desktops, laptops, servers, file shares, and cloud storage—to discover existing sensitive data
- 4.Document all sensitive data locations and classifications in a centralized inventory
- 5.Set DLP rules to monitor, alert, and block unauthorized transmission attempts (email, USB, cloud uploads)
- 6.Extend DLP oversight to remote service providers and third-party systems handling your data
- 7.Test DLP effectiveness regularly and refine detection patterns based on findings
- 8.Train users on DLP policies and sensitive data handling requirements
Evidence auditors look for
- DLP tool deployment documentation and configuration settings
- Sensitive data inventory with classifications and storage locations
- DLP policy rules and detection patterns
- Scan reports showing data discovery results across all assets
- Alert and block logs demonstrating DLP enforcement
- Third-party data processing agreements referencing DLP requirements
- User training records on data handling and DLP compliance
- Periodic DLP testing results and remediation actions
