The Wireless Broadband Alliance (WBA) has unveiled a comprehensive report on Wi-Fi Security Guidelines, aimed at enhancing the security, privacy, and trust of Wi-Fi networks globally.
These guidelines introduce an industry framework designed to bolster security across various environments, including public, enterprise, IoT, and roaming settings. With Wi-Fi playing a pivotal role in today's digital infrastructure, inconsistent security practices pose a range of risks, from credential theft to privacy violations. The new report seeks to mitigate these threats, offering organisations the tools to improve user trust and simplify network interoperability.
Standards-based framework
The WBA report centers around the need for carrier-grade security that matches user expectations. By leveraging established technologies like OpenRoaming™ and Passpoint®, it outlines a standards-based approach for thoroughly securing Wi-Fi networks. This spans from device authentication to physical and backhaul security, incorporating Layer-2 protection, RadSec, federation governance, and preparedness for post-quantum cryptography.

By integrating these security measures—such as encryption and identity privacy—Wi-Fi can offer secure and interoperable connectivity akin to cellular networks. Varying elements such as credential handling and control-plane signalling are addressed to ensure secure communication across networks.
Key security measures
To enhance Wi-Fi security, the guidelines propose several measures:
- Prevention of rogue network connections: Recommending mutual authentication using 802.1X and strong EAP methods, devices must validate network certificates to ensure connections to legitimate networks only.
- Data protection over the air: By implementing WPA2/WPA3-Enterprise with AES encryption and Protected Management Frames (PMF), traffic confidentiality and integrity are assured, mitigating risks of sniffing and various attack vectors.
- User identity privacy: Through techniques like anonymous identities and encrypted identities, the report balances privacy demands with necessitated compliance for lawful intercept and incident handling.
- End-to-end credential security: Emphasising secure storage on devices and within identity systems, the report safeguards credentials throughout their lifecycle.
- Comprehensive network hardening: By providing guidance for the physical security of access points and secure backhaul design, the report ensures protected data flow across network paths.
- AAA and roaming signalling security: Recommendations for RADIUS over TLS or DTLS secure all authentication and accounting traffic, aligning with OpenRoaming and WRIX standards.
- Layer-2 protection against attacks: Employing traffic inspection and client isolation techniques limits potential damage from malicious connectivity, reducing risks like ARP spoofing.
Interoperable Wi-Fi experiences
The WBA has also released a Wi-Fi Security FAQ, providing insight and understanding of modern Wi-Fi security. This resource is accessible on the WBA website.
Tiago Rodrigues, President and CEO of the WBA, remarked, “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.”
Modern enterprise communication
Cameron Dunn, Assistant Vice President, In-Building Solutions, AT&T Services, Inc., stated: "For operators, secure Wi-Fi is essential to delivering trusted and seamless connectivity at scale. What this work shows is that, by applying established best practices across authentication, encryption, identity privacy, signalling and federation governance, Wi-Fi can provide the level of security and consistency needed for modern roaming and offload use cases.”
Nick Hudson, COO for UK and Ireland at Boldyn Networks, praised the initiative, expressing: “At Boldyn Networks, we design and deploy advanced connectivity infrastructure for customers in many sectors who rely on our ability to provide secure and protected networks. We applaud WBA’s initiative to provide new Wi-Fi security guidelines and work together to continue shaping the industry standards.”
Phil Morgan, CTO at NC-Expert, echoed these sentiments, stating: “As wireless technology continues to underpin modern enterprise communication, we believe its security must be approached with precision, shared accountability, and oversight. These guidelines reflect our collective obligation to raise the standard of responsibility and governance.”
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 signalling attacks. The new guidelines will help organisations 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 signalling 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: Recognising 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
