Configuring the Wireless NetworkA Note About Wireless Security3Wireless Security TipsSince you cannot physically prevent someone from connecting to your wirelessnetwork, you need to take some additional steps to keep your network secure:• Change the default wireless network name or SSIDWireless devices have a default wireless network name or Service SetIdentifier (SSID) set by the factory. This is the name of your wirelessnetwork, and can be up to 32 characters in length.You should change the wireless network name to something unique todistinguish your wireless network from other wireless networks that mayexist around you, but do not use personal information (such as your SocialSecurity number) because this information may be available for anyone tosee when browsing for wireless networks.• Change the default passwordFor wireless products such as access points, routers, and gateways, youwill be asked for a password when you want to change their settings. Thesedevices have a default password set by the factory. The default passwordis often admin. Hackers know these defaults and may try to use them toaccess your wireless device and change your network settings. To thwartany unauthorized changes, customize the device’s password so it will behard to guess.• Enable MAC address filteringCisco routers and gateways give you the ability to enable Media AccessControl (MAC) address filtering. The MAC address is a unique series ofnumbers and letters assigned to every networking device. With MACaddress filtering enabled, wireless network access is provided solely forwireless devices with specific MAC addresses. For example, you canspecify the MAC address of each computer in your network so that onlythose computers can access your wireless network.Cisco RV120W Administration Guide 52
