DLP Deployment
Data Loss Prevention Policy Setup and Rollout
Project Introduction
For a legal agency requiring strict data compliance, Solorithm deployed an enterprise Data Loss Prevention (DLP) solution to identify, monitor, and protect sensitive files from unauthorized exfiltration.
Client Requirements
- Data Identification: Automatically discovering and classifying personally identifiable information (PII) and contract records.
- Multi-Channel Protection: Securing data-in-use, data-in-transit (email/web), and data-at-rest (file shares).
- Remediation Actions: Enforcing real-time blocks, encryption prompts, or alert notifications upon policy breach.
Architecture & Design
DLP Enforcer Engine: Central control server distributing rules and monitoring alert events.
Endpoint Agents: Lightweight agent software monitoring user actions, USB ports, and local storage.
Network gateway proxies: Intercepting web and email traffic to verify data compliance.
Deployment Process
- 1 Discovery Audits: Scanned on-premises and cloud repositories to locate unencrypted PII files.
- 2 Agent Rollout: Mass-installed DLP endpoint agents using group policy scripts.
- 3 Rule Mapping: Wrote patterns to look for credit card structures, SSNs, and custom legal templates.
- 4 Tuning: Began in "Audit-Only" mode to fine-tune filters, eventually advancing to "Block-and-Audit" mode.
Challenges & Mitigations
Conclusion & Handover
The DLP implementation secured the clients sensitive records, providing complete visibility into internal document transfers and preventing critical breaches of data protection laws.
