25.7 NetworkManager and Security
NetworkManager distinguishes two types of wireless connections, trusted and untrusted.
A trusted connection is any network that you explicitly selected in the past. All others
are untrusted. Trusted connections are identied by the name and MAC address of the
access point. Using the MAC address ensures that you cannot use a different access
point with the name of your trusted connection.
NetworkManager periodically scans for available wireless networks. If multiple trusted
networks are found, the most recently used is automatically selected. NetworkManager
waits for your selection in case that all networks are untrusted.
If the encryption setting changes but the name and MAC address remain the same,
NetworkManager attempts to connect, but rst you are asked to conrm the new en-
cryption settings and provide any updates, such as a new key.
If you switch from using a wireless connection to ofine mode, NetworkManager blanks
the SSID or ESSID. This ensures that the card is disconnected.
