A small business has an open wireless network so vendors can connect to the network without logging in.

The best way to address the small business owner's concern of unauthorized access to the open wireless network would be to implement MAC filtering. MAC filtering is a security feature that allows or denies access to a wireless network based on the Media Access Control (MAC) address of the wireless device.
A MAC address is a unique identifier assigned to every network interface controller (NIC) by the manufacturer. By configuring the wireless access point (WAP) to allow only the MAC addresses of approved vendors, the network can be secured from unauthorized access.
Changing the default SSID, power levels, content filtering, or firewall settings may enhance the security of the network, but they would not specifically address the concern of unauthorized access to the open wireless network.
Changing the default SSID would only change the name of the network, but it would not prevent unauthorized access. Power levels refer to the strength of the wireless signal, and adjusting them would not address the concern of unauthorized access. Content filtering is a security feature that blocks access to specific websites or content, and a firewall is a security device that controls traffic flow and protects against unauthorized access, but these features would not specifically address the concern of unauthorized access to the open wireless network.
Therefore, the best solution for the small business owner's concern would be to implement MAC filtering.
