Application of temporal and spatial role based access control in 802.11 wireless networks

In this study, we have investigated the security aspects of wireless local area networks and discussed the weaknesses associated with various conventional 802.11 security protocols such as WEP and 802.1X. We propose an architecture to control access to 802.11 wireless networks, based on roles, location and time information, using the tested wired network components such as VPNs and Firewalls. The presented architecture, in which temporal and spatial RBAC is implemented, reduces the security risks in enterprise level deployment of wireless LANs.
