Q: MAC addresses are coming up on my network. How do I block them?

A: Every device that is able to access either ethernet or wi-fi has a unique MAC (Media Access Control) address. Although the MAC address is hard-coded into the network chip, it can be spoofed.

Any quality router will include the ability to turn on MAC Address Filtering. Once activated, enter the MAC addresses of your own devices as “allowed”, and then disallow any other MAC address from the network.

Now retrace your network security:

  1. Are your WiFi passwords strong?
  2. Have you changed your WiFi passwords recently?
  3. Are your network communications encrypted using WPA2 AES?
  4. Are your storage devices encrypted?
  5. Are there ethernet jacks that can be accessed by others without notice?
