Figure 6- 66. Example of Typical Port-Based Configuration

Once the connected device has successfully been authenticated, the Port then becomes Authorized, and all subsequent
traffic on the Port is not subject to access control restriction until an event occurs that causes the Port to become
Unauthorized. Hence, if the Port is actually connected to a shared media LAN segment with more than one attached
device, successfully authenticating one of the attached devices effectively provides access to the LAN for all devices on the
shared segment. Clearly, the security offered in this situation is open to attack.
