| Wireless Security:: WEP(Wireless Encryption Protocol) Enable the highest level of WEP that ships with the access point. SSID(Service Set ID) Change the default SSID that ships with your access points and/or wireless router. Mode Implement infrastructure mode, where all wireless clients on the network link directly via an access point or wireless router. Disable the "Ad-Hoc" mode, which enables a peer-to-peer network and that allows a user to connect with other wireless LAN cards. MAC Address Authentication Set up MAC address authentication via access control lists (ACLs). Configure your access points so they allow only clients with specific MAC addresses to access the network, or allow access to only a given number of MAC addresses. Broadcast Disable the "broadcast" mode in which access points periodically transmit their SSIDs. Since hackers know the default names of many access points, they can use freeware utilities, or even Windows® XP, to find the names of nearby wireless networks. Subnets. Place access points on separate subnets and put a firewall between that subnet and the main corporate network. VPN(Virtual Private Networking) Implement VPN over wireless LAN. This technology makes it possible for users to communicate securely via a VPN tunnel between the client desktop or notebook PC and the wireless access point or router. Educate The more network users know and understand about the security risks of wireless the less chances of intrusion. Enforce a wireless security policy. |
