The Gramm-Leach-Bliley Act (GLBA) is not vague. It demands control over how you collect, store, transmit, and protect customer financial data. GLBA compliance is not just about avoiding fines. It is about building trust, keeping systems secure, and proving that your security program works every day.
What GLBA Requires
GLBA compliance has three main pillars: the Financial Privacy Rule, the Safeguards Rule, and the Pretexting provisions.
- The Financial Privacy Rule: Disclose how you share and protect customer information. Give customers the right to opt out.
- The Safeguards Rule: Maintain a written, consistent security plan to protect information.
- The Pretexting Protection: Prevent social engineering attacks that attempt to gain unauthorized access to customer data.
The Safeguards Rule (GLBA SRE) should be at the center of your security roadmap. It requires a risk analysis, ongoing monitoring, periodic testing, and adjustments when threats shift. GLBA SRE is about showing measurable security evidence, not just checking boxes.
Core Steps for GLBA SRE Compliance
Start with a full inventory of what financial data you handle. Map data flows across applications, APIs, and infrastructure. Identify all points of storage, encryption, and transmission.
Set up hardened access controls. Role-based access and MFA can remove entire categories of risk.
Implement encryption in transit and at rest for all financial data. No exceptions.
Log and monitor every interaction with sensitive data. Set up alerts for failed login attempts, privilege escalations, and unusual data queries.
Run penetration tests and security audits at regular intervals. Validate controls under realistic attack scenarios.
