Operating System Support Currently client devices pose the largest potential problem when deploying 802.1X. Whilst modern operating systems such as Microsoft® Windows Vista/XP®, Mac OS X® 10.4/10.5 and Linux® natively support 802.1X, older OS such as Microsoft® Windows 98/ME® do not. Additionally there are many other devices on the network which do not support 802.1X such as printers, network music player, desktop hubs/switches, and the current iPhone (Firmware 1.1.4.). Workarounds must be found if these devices are to continue functioning on the network.

Prerequisites To deploy 802.1X within your organisation you will require suitable infrastructure capable of supporting it.

Readers are assumed to have a basic knowledge of networking concepts and preventive security awareness. A companion technical guide Security Matters is available.
