![]() It’s obviously still a major privacy concern, but not really in the sense that a hacker can use it to gain access to your data or anything of the sorts. It’s more about knowing your location, ID you and possibly, choosing which ads to serve to you afterwards. But does it matter? Yes, but not really in the way you may think. The moment a device is connected to a WiFi network, the WiFi MAC address becomes known to the other devices within the local LAN, so, if you decide to connect your smartphone to an Airport or hotel WiFi network, the admin can see the MAC address of your handset. What can happen when someone knows the MAC address of my devices? Consequences of spoofing the MAC address.Changing the channel, but not the channel bandwidth.What can happen when someone knows the MAC address of my devices?.(Finally, were you to use a Proxy or NAT, then the MAC address would be reset in that way, but this is probably not what you are looking for. The physical port number can be tied to a specific IP address and MAC address requirement.īesides a proper Managed Switch, many Routers, or small computers with multiple ethernet ports have the ability to enforce such restrictions. For example, with a Managed Switch, each PC can be plugged into a separate port. The best thing to do would be to have a middle-man device which controls the traffic. Properly securing a machine when someone has physical access is quite complex and depends on the specific requirements.Īnd besides that, could someone just unplug the network cable and plug it into a a separate device for which they have root access? However, with physical access to the machine, there are many possible ways to bypass the user account controls, and gain administrator access anyway. So, if you do not trust the user, or want to reduce the risk of viruses, you should certainly run a non-administrator account. (There may be network cards which use a fixed MAC address, but I've not yet heard of them.)Īs the comments suggest, an Administrator account in Windows can adjust the MAC address, as well as the IP address. ![]()
