Example embodiments disclosed herein relate to authentication based on Media Access Control (MAC) addresses. A network security device receives one or more client identity databases from one or more edge network devices. The client identity databases include MAC addresses of clients and secondary identification information for each of the clients. The network security device determines that a client device has been connected to one of the edge devices. A security action is performed based on whether the MAC address and respective secondary identification information of one of the clients matches the MAC address and respective secondary identification information of the connected client device. |
