Network Services for Authentication
For Wireless LAN Vendors
Essential Network Services for Authentication and 802.1X
The Infoblox Network Services for Authentication package provides reliable and highly available authentication services for all
major wireless LAN (WLAN) vendors.
802.1X Authentication: New Opportunities, New Challenges
802.1X is the industry standard for authenticating network access, and is the key element for ensuring security in wired and
wireless networks and for enabling new security initiatives such as network access control (NAC). 802.1X requires three
components: the supplicant, which is software on the client device; the network access device (aka the authenticator), which is
typically a wireless access point or a wired switch; and an authentication server, which communicates with the network access
device using RADIUS. With 802.1X, the authentication server becomes a key component of the network infrastructure. If the
authentication server fails or becomes unreachable, all access to the network may be denied. As such, network authentication
services must be deployed with the highest possible reliability, and the overall system design must sustain against the failure of
servers or the WAN links among remote network access devices and centralized user directories.

802.1X Authentication: Infoblox Solution
Infoblox reliably solves all the distribution issues with RADIUS for WLAN services. The solution uses a combination of Infobox
appliances, ID grid technology, and the Infoblox replication agent, software that runs on the Microsoft domain controller and
securely replicates user credentials (user names and passwords) from the domain controller to the grid master and stores them
in the built-in Infoblox bloxSDB™ database. The credentials are then replicated over a secure VPN to all Infoblox appliances in
the grid. When an appliance is deployed in a branch office, it can provide authentication services for 802.1X even during a WAN
outage that makes the Infoblox grid master (and the Active Directory server) unreachable. Infoblox NIOS™ software also has
built-in hardware based high-availability (HA) technology that provides an extra layer of reliability by enabling appliances to be
deployed in redundant pairs. Infoblox solutions work with most major WLAN vendors. Please contact your local Infoblox sales
person or channel partner to get more information.
