 * SECTION:nm-setting-wireless-security
 * @short_description: Describes connection properties for Wi-Fi networks that
 * use WEP, LEAP, WPA or WPA2/RSN security
 *
 * The #NMSettingWirelessSecurity object is a #NMSetting subclass that describes
 * properties necessary for connection to encrypted Wi-Fi networks.
 *
 * It's a good idea to read up on wpa_supplicant configuration before using this
 * setting extensively, since most of the options here correspond closely with
 * the relevant wpa_supplicant configuration options.  To get a better overview
 * of how Wi-Fi security works, you may want to get copies of the following books.
