The following types of WiFi connections are more secure:
Connecting to a private, restricted-access WiFi network.
Private networks, such as internal networks that are established by corporations or universities, restrict network access to users who can provide the correct security challenge. Potential users must supply a key during the connection sequence or log in to the network through a secure VPN application.
Encrypting your connection to a WiFi network.
You can encrypt communications between your system and a WiFi network by using a secure key. Your access point to the WiFi network must be a router that is in your home or office with a secure key-generating feature. Your system and the router establish and then share the key before creating the secure connection.
The dladm command can use a WiFi Protected Access (WPA) key for encrypting connections through an access point. The WPA protocol is defined in the IEEE 802.11i specifications for wireless connections. Oracle Solaris supports version 2 of the WPA standard. See the dladm(8) man page.
