Final answer:
MAC filtering in wireless networking enhances security by allowing only devices with specific MAC addresses to connect, offering a layer of security against unauthorized access, but is optimally combined with other security measures.
Step-by-step explanation:
The benefit of MAC filtering in wireless networking is that the network is more secure. MAC filtering is a security feature that controls access to a network based on the physical, hardware addresses (known as MAC addresses) of devices. When MAC filtering is enabled on a router, only devices with specific MAC addresses are allowed to connect to the network. This helps to prevent unauthorized devices from accessing network resources. However, it is important to note that MAC filtering is not foolproof; it adds a layer of security but can be bypassed by a determined intruder who can spoof MAC addresses. It is best used in conjunction with other security measures such as strong encryption to help protect the network.
