Monitoring, troubleshooting and analytics of Wi-Fi deployments, including help desks, often rely on MAC addresses as part of the client identity.

MAC address filtering is often used to add an extra layer of protection on the network (white/blacklist) and enforce policies such as parental control.

Some accounting and billing systems use the MAC address as a unique device identifier.

MAC-based access often admits or denies wireless association based on the connecting device’s MAC addresses. This includes authentication methods using the MAC address in lieu of a username and password, Pay Per Use (PPU) passes and short-term complimentary services.

In a recent Liaison Statement to the Wireless Broadband Alliance, the IEEE 802.11 working group “strongly recommends against using any specific MAC address as an identifier for a user or device, outside the scope of the layer 2 communication.” However, due to its ubiquity and, so far, expected uniqueness, the MAC address is widely used for various purposes, such as security, access control and billing. To address these concerns, IEEE 802.11 recently formed a Random and Changing MAC Addresses (RCMA) group that is assessing the impact of changing MAC addresses on 802.11 features, for both associated and unassociated device states.īecause the MAC address is a Layer 2 identifier, its usage was not intended for beyond L2 networking. For example, band steering and client steering that optimize client connectivity in a multiple AP environment depend on a unique MAC address for probes and association. Changing MAC address can also negate the effectiveness of some wireless features. The concerns can be classified into two major categories depending on how/where the MAC address is used, the L2 network layer or the system layer.Īt Layer 2, MAC address randomization can impact network components: One client may be reported multiple times, and networking equipment might be filled up with outdated MAC addresses. … But Raises Concerns Over Networking Equipment and ServicesĪlthough MAC address randomization is evidently a major step toward user privacy, it can have a wide range of repercussions impacting the Wi-Fi network and other related services.

Windows 10 implements a similar scheme, while iOS 12 supports the probe mode only.

This feature was added to Android P for experimental purposes, whereas Android Q randomizes the MAC address by default, with per-network customization. The address is kept consistent per network (i.e., Service Set Identifier ), so the user doesn’t have to authenticate each time it connects to the same SSID. More recently, OSs have started to implement the use of MAC address randomization for device association to the network.

IEEE 802.11 also stepped up to specify a similar feature in the IEEE 802.11aq Pre-Association Service Discovery amendment to the 802.11-2016 standard. This probe mode guarantees anonymity until the client gets associated with an AP. In response to these privacy vulnerabilities, most OSs-including Android, iOS, and Windows-began to implement their own variant of MAC address randomization while probing the Wi-Fi network. MAC Address Randomization Increases Device Anonymity …

In addition, during the connection to the AP, customers were not notified upfront that their movements would be tracked, and historic location data could be used for marketing purposes or sold to third parties. Several companies were reportedly logging and tracking the addresses of nearby devices in unassociated states.

The MAC address is a Layer 2 (L2) address used to identify the source (sender) and the destination (receiver) of frames by most 802 network technologies, including Ethernet, Bluetooth and Wi-Fi.īack in 2013, the privacy implications of targeted probe requests started to become widely publicized. Unique MAC Addresses Enable User Privacy Infringement in Wireless NetworksĮvery Wi-Fi radio has a unique 48-bit identifier called a MAC address that is assigned by the manufacturer. As a countermeasure to this privacy threat, OS developers are anonymizing MAC addresses, thereby raising technical concerns among network operators. Wi-Fi access points, however, can monitor device locations without user consent by means of MAC addresses. Although a growing number of applications make use of location data, operating systems (OSs) provide the ability to turn off location services provided by the GPS or cellular/Wi-Fi connectivity.
