MAC-Spoofing
MAC Spoofing is a technique used in computer networking that involves changing the unique identifier of a network interface controller (NIC) known as the Media Access Control (MAC) address.
The MAC address is a 48-bit unique identifier assigned to each network-enabled device, and is used to regulate access to network resources by identifying the devices that are authorized to access them. MAC Spoofing is used to trick devices on a network into thinking that the MAC address of the attacker’s device is actually that of an authorized device, enabling the attacker to gain access to the network resources illegally.
MAC Spoofing is often used by attackers looking to gain unauthorized access to a network or evade detection while carrying out malicious activities such as phishing, data theft, and network reconnaissance. To prevent MAC Spoofing, network administrators can implement security measures such as configuring strict access control lists (ACLs), using port-based security such as IEEE 802.1x authentication, and monitoring network traffic for suspicious activity.
