On a wireless network, the device with the proper credentials such as SSID and password can authenticate with the router and join the network which gets an IP address and access to the internet and any shared resources. Media access control may seem advantageous but there are certain flaws. The router has a number of functions designed to improve the security of the network but not all are useful. The router allows configuring a list of allowed MAC addresses in its web interface, allowing you to choose which devices can connect to your network. It increases the efficiency of access to a network The access point can be configured to only allow clients to talk to the default gateway, but not other wireless clients. It is used on enterprise wireless networks having multiple access points to prevent clients from communicating with each other. White lists provide greater security than denied lists because the router grants access only to selected devices. We can configure the filter to allow connection only to those devices included in the white list. In a way, we can denied list or allowed list certain computers based on their MAC address. It helps in preventing unwanted access to the network. It helps in listing a set of allowed devices that you need on your Wi-Fi and the list of denied devices that you don’t want on your Wi-Fi. In this, each address is assigned a 48-bit address which is used to determine whether we can access a network or not.
MAC filtering is a security method based on access control. Each adapter has a distinct label known as a MAC address which recognizes and authenticates the computer. A wired adapter allows us to set up a connection to a modem or router via Ethernet in a computer whereas a wireless adapter identifies and connects to remote hot spots.
