The Wireless Broadband Alliance (WBA) has published new Wi-Fi Security Guidelines, offering a comprehensive industry framework designed to enhance security, privacy, and trust across various Wi-Fi networks.
The updated guidelines target environments such as public, enterprise, IoT, and roaming, ensuring robust protection from threats like rogue access points, credential theft, privacy breaches, and signaling attacks. These guidelines aim to help organizations mitigate common Wi-Fi threats and improve interoperability across diverse networks.
Standards-Based Framework
Addressing the demand for improved carrier-grade security, the framework is based on widely used technologies like OpenRoaming™ and Passpoint®.
The guidelines promote measures for authentication, encryption, identity privacy, and more
It defines a standards-based approach to securing Wi-Fi from device authentication to backhaul security, including Layer-2 protection and governance for federation readiness in a post-quantum cryptographic world. The guidelines promote measures for authentication, encryption, identity privacy, and more, to ensure secure connectivity akin to that of cellular networks.
Validate Network Certificates
- Prevent Rogue Network Connections: The report emphasizes mutual authentication using 802.1X and strong EAP methods. Devices are required to validate network certificates to avoid unauthorized access, reducing risks from rogue access points.
- Data Protection: With WPA2/WPA3-Enterprise and AES encryption protocols, traffic confidentiality and integrity are safeguarded. These measures protect against passive sniffing and various attacks, aligning Wi-Fi security closer to that of cellular networks.
- User Identity Privacy: Privacy is balanced with traceability through anonymous identities and pseudonyms, offering protection while enabling lawful intercept and billing.
- End-to-End Credential Security: Credentials receive protection throughout their lifecycle, mandating secure OS key stores and tamper-resistant SIM technology to decrease the risk of large-scale theft.
- Network Hardening: Physical security of access points, encrypted links, and secure backhaul designs ensure comprehensive network traffic protection.
- AAA and Roaming Security: The guidelines recommend RADIUS over TLS/DTLS for secure AAA and roaming exchange, aligning with OpenRoaming and WRIX requirements.
- Layer-2 Attack Protections: Implementing traffic inspection and client isolation limits potential damage from malicious devices.
- Federation and Governance Enforcement: The guidelines reinforce operational security through frameworks like OpenRoaming and WRIX.
Interoperable Wi-Fi Experiences
The WBA has also introduced a Wi-Fi Security FAQ for users and network operators, providing clarity on applying modern Wi-Fi security measures. Tiago Rodrigues, President and CEO of the WBA, highlighted the critical role of Wi-Fi in global connectivity and how these guidelines can elevate Wi-Fi security standards to align with cellular networks.
Cameron Dunn from AT&T Services emphasized the importance of secure Wi-Fi for seamless connectivity, while Nick Hudson from Boldyn Networks and Phil Morgan from NC-Expert recognized the initiative as a crucial step in setting industry standards and enhancing trust in enterprise communication.
The Wireless Broadband Alliance (WBA), the global industry body dedicated to driving the seamless and interoperable service experience of Wi-Fi across the global wireless ecosystem, releases a new Wi-Fi Security Guidelines report. The guidelines define a new industry framework designed to strengthen security, privacy and trust across Wi-Fi networks, including public, enterprise, IoT and roaming environments.
Today, Wi-Fi underpins critical digital services for consumers, businesses and connected devices, yet inconsistent or fragmented security practices can expose users and operators to risks ranging from rogue access points and credential theft, to privacy breaches and signaling attacks. The new guidelines will help organizations reduce exposure to common Wi-Fi threats, improve user trust, and simplify interoperability across networks and partners. For operators and enterprises, this results in more predictable security outcomes and greater confidence when deploying or scaling Wi-Fi services.
Standards-based framework
The guidelines address the growing need for carrier-grade security that aligns with user expectations. Built on widely deployed technologies including OpenRoaming™ and Passpoint®, the report sets out a clear, standards-based framework for securing Wi-Fi end-to-end, from device authentication through to physical and backhaul security, Layer-2 protection, RadSec adoption, federation governance and readiness for post-quantum cryptography.
Implemented together, interoperable measures across authentication, encryption, identity privacy, credential handling, infrastructure, control-plane signaling and federation governance, enable Wi-Fi to deliver secure, privacy-preserving and interoperable connectivity comparable to cellular networks.
Validate network certificates
The guidelines on securing Wi-Fi networks are designed to:
- Prevent connections to rogue and fake networks: Wi-Fi security starts with trust. The report mandates mutual authentication using 802.1X and strong EAP methods, requiring devices to validate network certificates before sharing credentials. This ensures users only connect to legitimate networks and significantly reduces the risk of evil-twin and rogue AP attacks
- Protect data over the air: By enforcing WPA2/WPA3-Enterprise with AES encryption and Protected Management Frames (PMF), the report ensures traffic confidentiality and integrity. This prevents passive sniffing, deauthentication attacks, and many man-in-the-middle techniques, bringing Wi-Fi security closer to cellular-grade protection
- Preserve user identity privacy without breaking compliance: The report balances privacy and traceability by using anonymous identities, encrypted inner identities, pseudonyms, and Chargeable-User-Identity (CUI). This protects personally identifiable information during authentication while still enabling lawful intercept, billing, and incident handling when required
- Secure credentials end-to-end: Credentials are protected throughout their lifecycle, from device to network to backend systems. The report requires secure OS key stores on devices, hardened credential storage in identity provider systems, and tamper-resistant SIM and USIMs for mobile credentials, reducing the risk of large-scale credential theft
- Harden the entire access network: Security extends beyond the radio link. The report provides guidance for physical security of access points and controllers, encrypted AP-to-controller links, secure backhaul design, and local breakout architectures, ensuring traffic remains protected across the full network path
- Secure AAA and roaming signaling: Recognizing that the control plane is often overlooked, the report strongly recommends RADIUS over TLS or DTLS for all AAA and roaming exchanges. This protects authentication and accounting traffic from interception or manipulation, aligning with OpenRoaming and WRIX requirements
- Add Layer-2 protections against lateral attacks: To limit damage even if a malicious device connects, the report promotes Layer-2 traffic inspection, client isolation, proxy ARP, and multicast and broadcast controls, reducing client-to-client attacks such as ARP spoofing and broadcast abuse
- Enforce security through federation and governance: Security is reinforced not only technically but operationally. Through OpenRoaming and the WRIX legal framework, security requirements, responsibilities, and privacy obligations are consistently enforced across operators, identity providers, and hubs
Interoperable Wi-Fi experiences
The WBA has also created a Wi-Fi Security FAQ alongside the new guidelines. It gives users, enterprises and network operators a clear and accessible understanding of how modern Wi-Fi security works and can be seen at the WBA website.
Tiago Rodrigues, President and CEO of the Wireless Broadband Alliance, said: “Today, Wi-Fi underpins critical connectivity for consumers, enterprises and IoT at global scale. These guidelines show how proven standards and best practices can be applied consistently to deliver secure, privacy-preserving, and interoperable Wi-Fi experiences. By aligning security across devices and networks, Wi-Fi achieves parity with cellular in security capability and confidence.”
