Q&A
PROTECTED EXTENSIBLE AUTHENTICATION PROTOCOL
This document answers questions about Protected Extensible Authentication Protocol.
OVERVIEW
Q.
What is Protected Extensible Authentication Protocol?
A.
Protected Extensible Authentication Protocol (PEAP) is an 802.1X authentication type for wireless LANs (WLANs). PEAP provides strong
security, user database extensibility, and support for one-time token authentication and password change or aging. PEAP is based on an Internet
Draft (I-D) submitted by Cisco Systems
®
, Microsoft, and RSA Security to the IETF. Glen Zorn was the Cisco Systems
®
lead engineer and coauthor
of this I-D.
Q.
Is PEAP supported by the Cisco Unified Wireless Network, Wi-Fi Protected Access (WPA) and Wi-Fi Protected Access 2 (WPA2)?
A.
Yes. The
Cisco Unified Wireless Network
supports several EAP authentication types, including PEAP. Like all EAP types, PEAP can
be used with WPA and WPA2 networks.
Q.
What is the Cisco Unified Wireless Network?
A.
The Cisco Unified Wireless Network is the industry’s only unified wired and wireless solution to cost-effectively address the WLAN security,
deployment, management, and control issues facing enterprises. This powerful solution combines the best elements of wireless and wired
networking to deliver scalable, manageable, and secure WLANs with a low total cost of ownership. It includes innovative RF capabilities that enable
real-time access to core business applications and provides proven enterprise-class secure connectivity. The Cisco Unified Wireless Network delivers
the same level of security, scalability, reliability, ease of deployment, and management for wireless LANs that organizations expect from their wired
LANs.
The Cisco Unified Wireless Network supports an enterprise-ready, standards-based, wireless security solution that gives network administrators’
confidence that their data will remain private and secure when they use Cisco wireless products, Cisco Aironet Series products, Cisco Compatible
Extensions products or Wi-Fi Certified WLAN client devices. This enterprise-class wireless security solution supports robust wireless LAN security
services that closely parallel the security available in a wired LAN. It fulfills the need for consistent, reliable, and secure mobile networking by
delivering industry-leading WLAN security services. It mitigates sophisticated passive and active WLAN attacks, interoperates with a range of
client devices and provides reliable, scalable, centralized security management. The Cisco Unified Wireless Network allows network administrators
to deploy large-scale enterprise WLANs with scalable problem-free security administration that does not increase the burden on the IT staff.
Q.
Is PEAP a standard?
A.
Not yet. PEAP is based on an I-D submitted to the IETF. Cisco, Microsoft, and RSA Security are actively involved in the IETF standards body
supporting a standardized PEAP implementation.
Q.
Where can I find information about the PEAP draft proposed to the IETF?
A.
Please visit the IETF I-D
Search Engine
and search for “PEAP.”
