Which Of These Is A Vulnerability Of Mac Address Filtering?
Sometimes I need to configure the router and choose which devices can connect to my network (MAC address filtering). For example, limit connections to 3 specific machines. But for an advanced user, it is possible to get my MAC address and change it easily (e.g. On a Linux machine using a simple command line macchanger --mac xx:yy:zz:tt:aa:bb wlan0)
According to gowen fawr, if one of my 3 machines isn't connected, it's possible for an advanced user to reconnect in its place.
To get more security features, what is the right configuration of MAC address filtering: enabled or disabled?

MAC Address Filtering Provides No Security But MAC addresses can be easily spoofed in many operating systems, so any device could pretend to have one of those allowed, unique MAC addresses. MAC addresses are easy to get, too.
