Explanation
MAC address filtering creates a whitelist of hardware MAC addresses (unique identifiers burned into each network adapter) on the access points. Only devices whose MAC addresses appear on that approved list can connect, making it an effective technical control for restricting access to known, company-owned devices. Auto-configure scripts and user training rely on cooperation and are easily bypassed. WPA2-Personal with a strong password restricts access by credential, not device identity - any device with the password can connect.
