Summary

Gopi Mannava, Chief Data Architect for the State of Connecticut, outlines five architectural patterns crucial for establishing secure, role-based access in government Business Intelligence (BI) environments. Drawing from over a decade of experience building national-scale intelligence infrastructure, Mannava emphasizes that government BI security is a legal and fiscal obligation, distinct from private sector practices. The patterns include separating data and report access security, building role hierarchies that reflect legal and organizational structures, and leveraging dynamic session variables for auditable governance. Additionally, he advocates for designing security architectures with future upgrades in mind through independent documentation and integrating ongoing user training as a critical security control. This approach ensures a defensible architecture that withstands exceptions and supports modern government initiatives like AI-driven executive intelligence.

Key takeaway

For government BI architects designing or upgrading data systems, prioritize a defensible security architecture that mirrors legal and organizational structures. You must enforce security at both data and report layers, using dynamic session variables for auditable access control. Document your security framework independently of specific tools to ensure smooth upgrades and mitigate compliance risks. Implement continuous user training to strengthen your overall security posture.

Key insights

Government BI security demands a deliberate, multi-layered architecture driven by legal mandates and auditable processes.

Principles

• Government BI security is a legal and fiscal obligation.
• Security must be enforced at both semantic and presentation layers.
• Role architecture must align with legal mandates.

Method

Design security as a deliberate architecture, documenting all role definitions, row-level filters, and session initialization blocks as a standalone, governed artifact.

In practice

• Define data-level row filters in the Business Model layer.
• Implement dynamic session variables for query context.
• Document security architecture independently of tool versions.
