WRIX-S – Security Standard

TRENDS AND OPPORTUNITIES

WRIX-S addresses the growing need for consistent, high-assurance security across Wi-Fi roaming as adoption expands through OpenRoaming™, private 5G/Wi-Fi interworking, and global identity federation.

WRIX’s strong foundation of “hard” requirements can be further enhanced with clearer configuration guidance, enabling more consistent, secure, and interoperable vendor implementations.

WRIX-S offers an opportunity to harmonize security practices, covering TLS binding, RadSec validation, Personally Identifiable Information (PII) protection, AP security, and accounting integrity, ensuring Wi-Fi can deliver cellular-grade trust.

Rising regulatory expectations, increasing deployment complexity, and demand for secure enterprise and public Wi-Fi roaming further position WRIX-S as a critical enabler of scalable, interoperable, and compliant roaming ecosystems.

BUSINESS & MARKET BENEFITS

WRIX-S strengthens Wi-Fi roaming by enhancing the WRIX Framework with clear, practical security configuration guidance.

This delivers meaningful business and market benefits, including higher trust and smoother onboarding between roaming partners through standardized security expectations.

Vendor-neutral best practices reduce operational complexity, lower troubleshooting costs, and improve deployment reliability.

A more predictable security environment increases confidence in OpenRoaming and encourages broader ANP and IDP participation.

WRIX-S also promotes competitive fairness by aligning diverse vendor implementations and establishes a strong foundation for future assurance or certification programs, supporting long-term ecosystem interoperability.

EXPECTED OUTCOMES

The WRIX-S initiative aims to strengthen Wi-Fi roaming security by introducing clear, actionable configuration guidance across the entire WRIX framework. Through a comprehensive audit of WRIX-n, WRIX-i, WRIX-l, and WRIX-d/f, the project will identify technology, security, and privacy gaps and define best practices to securely implement each requirement.

Key Deliverables

A complete WRIX-S specification detailing secure configurations for all WRIX-related controls.

Updated WRIX documents to close identified security gaps.

Harmonized guidance for TLS binding, RadSec validation, PII protection, AP security, and accounting safeguards.

Integration of WRIX-S into the full WRIX document suite.
