Spoofing Media Access Control (MAC) & Its Counter Measures

The IEEE 802.3 MAC Protocol is the standard for LAN Ethernet Card in Computer Architecture. An adversary can exploit this vulnerability of 802,3 Protocol to launch a large number of attacks. When computers connect together on a network, a network card or wireless network card are typically used. Each network card or wireless network card has a Media Access Control (MAC) address that is used to tell them apart. The MAC address is a series of 12 characters usually in the form xx-xx-xx-xx-xx-xx and is burned into the hardware of a network card. The first 6 characters distinguish what company made the card and the rest are unique to identify that specific card.
