Data Protection with Advanced MFA: How to Stop Data Breaches at the Database Layer


The Last Mile of Data Protection

You have MFA on M365 and VPN. But your DBAs and developers still access production MySQL, MSSQL, Oracle, and PostgreSQL with just a password.

DB credentials are often shared, hardcoded in scripts, and never rotated. This is where data leaves the company.

Why Traditional Database Security Fails

  • Service accounts with standing privileges
  • Shared sa or root passwords
  • No MFA at the DB protocol layer
  • No visibility into who ran DROP TABLE

What is Advanced MFA for Data Protection?

Advanced MFA moves MFA enforcement to the database layer itself.

AuthNull's 3-Layer Approach

Layer 1: Database Logon MFA

Every database login, even via SQL client or application, requires MFA. We install a lightweight agent on the DB server that hooks into the login flow — no application code change needed.

Layer 2: Just-in-Time Access + Vaulting

No standing DB passwords. The user requests access in the AuthNull portal, a manager approves, and a password is auto-rotated and checked out for 1 hour. After use, the password is auto-rotated again.

Layer 3: Session Recording

Every query in a privileged session is recorded for audit — who accessed customer data and when, a full answer for GDPR auditors.

Use Cases

  • Protect PII/Financial Data — enforce MFA for any access to a DB containing customer data.
  • Stop Insider Threats — even a DBA cannot access prod without approval + MFA.
  • Compliance Ready — meets PCI-DSS 8.3, GDPR Article 32, and HIPAA requirements for advanced authentication for data access.

Result

One AuthNull customer, a fintech, prevented a major breach when a developer's laptop with saved DB credentials was stolen. The thief had a password, but not the second factor.

Don't just protect the front door. Protect the vault where your data lives. Explore AuthNull Database MFA.
