Designing a Secure Wireless LAN with the HP-UX AAA RADIUS Server

4. Network topology is not affected (like VPN and VPN gateways).

5. Can leverage existing authentication (AAA RADIUS can integrate).

Disadvantages are:

1. New client software required (supplicant).

2. New technology means possible interoperability issues (clients and access

points).

3. Data only protected from the client to the access point (okay if the internal

network is secure).

A.7 Summary

VPN deployments already exist in many enterprise networks. VPNs should be used to secure

access from external WLAN networks into the corporate enterprise networks. They may also be

used in to secure internal WLAN access to enterprise networks in place of WLAN security, albeit

at a significant cost. In the best case, VPN and WLAN security are deployed as complementary

methods of securing both remote and wireless access to the enterprise network
