In a nutshell, network security involves protecting network devices and the data that they forward. The basic components of a network, which act as the front-line gatekeepers, are the router, the firewall, and the switch. Figure 15.1 shows these core components.
NOTE: If your wireless network has no security enabled, then you only need to know the value of the Network ID (SSID) field. 802.1X, WPA and WPA2(AES) security is generally used in enterprise networks and most likely your laptop will be pre-configured to connect to your corporate wireless network.
