What is MAC-based authentication?

Media Access Control (MAC) authentication is used to authenticate devices based on their physical MAC addresses. It is an early form of filtering. MAC authentication requires that the MAC address of a machine must match a manually defined list of addresses.

What authentication standard is performed by an NPS?

NPS supports both password-based and certificate-based authentication methods. However, not all network access servers support the same authentication methods. In some cases, you might want to deploy a different authentication method based on the type of network access.

Is Mac-based authentication secure?

BEST PRACTICE: MAC-based authentication is not as secure as agent access or agentless access authentication. MAC addresses are not generally guarded as secrets, so an attacker can spoof a MAC address and impersonate a device to gain network access.

What port does NPS use for authentication accounting?

However, by default, many access servers use ports 1645 for authentication requests and 1646 for accounting requests.

Why should I deploy Mac-based access control using Microsoft NPS?

Because the MAC address of the device is used as the credentials, an attacker can easily gain network access by spoofing the MAC address of previously authenticated clients. Below are the steps necessary in order, to deploy MAC-Based Access Control using Microsoft NPS.

Can I use a full MAC address for authentication?

If you define the full mac address such as AA:BB:CC:DD:EE:FF, only the end device that uses this mac address will get authenticated and every other device will get it’s authentication attempt refused. From the configuration you posted, there seems to be no problem. Best Regards, Candy

How do I set up a connection request policy in NPS?

1) In the NPS Server Console, navigate to NPS (Local) > Policies > Connection Request Policies. 2) Right click on Connection Request Policies, and select New. 3) Name the policy and select Next. 4) On the Specify Conditions page add the following condition: NAS port type as Ethernet (Figure 3) followed by clicking Next.

What is Mac based access control used for?

MAC-Based Access Control It is critical to control which devices can access the wireless LAN. MAC-Based Access Control can be used to provide port based network access control on MR series access points. With MAC-Based Access Control, devices must be authenticated by a RADIUS server before network access is granted on an SSID.
