of ISP's and organizations whose computers are taken over as bots and used to attack other firms. Mobile devices With increasing number of mobile devices with 802.1X interfaces, security of such mobile devices becomes a concern. While open standards such as Kismet are targeted towards securing laptops, access points solutions should extend towards covering mobile devices also. Host based solutions for mobile handsets and PDA's with 802.1X interface. Security within mobile devices fall under three categories: Protecting against ad hoc networks Connecting to rogue access points Mutual authentication schemes such as WPA2 as described above Wireless IPS solutions now offer wireless security for mobile devices. Mobile patient monitoring devices are becoming an integral part of healthcare industry and these devices will eventually become the method of choice for accessing and implementing health checks for patients located in remote areas. For these types of patient monitoring systems, security and reliability are critical, because they can influence the condition of patients, and could leave medical professionals in the dark about the condition of the patient if compromised. Implementing network encryption In order to implement 802.11i, one must first make sure both that the router/access point(s), as well as all client devices are indeed equipped to support the network encryption. If this is done, a server such as RADIUS, ADS, NDS, or LDAP needs to be integrated. This server can be a computer on the local network, an access point / router with integrated authentication server, or a remote server. AP's/routers with integrated authentication servers are often very expensive and specifically an option for commercial usage like hot spots. Hosted 802.1X servers via the Internet require a monthly fee; running a private server is free yet has the disadvantage that one must set it up and that the server needs to be on continuously. To set up a server, server and client software must be installed. Server software required is an enterprise authentication server such as RADIUS, ADS, NDS, or LDAP. The required software can be picked from various suppliers as Microsoft, Cisco, Funk Software, Meetinghouse Data, and from some open-source projects. Software includes: Aradial RADIUS Server Cisco Secure Access Control Software freeRADIUS (open-source) Funk Software Steel Belted RADIUS (Odyssey) Microsoft Internet Authentication Service Meetinghouse Data EAGIS SkyFriendz (free cloud solution based on freeRADIUS) Client software comes built-in with Windows XP and may be integrated into other OS's using any of following software:
