What security measure is an example of technical control in a home network?

The example of a technical control in a home network is configuring MAC address filtering. This practice involves setting up the network devices to allow or deny access based on the Media Access Control (MAC) addresses of the devices attempting to connect to the network. By specifying which MAC addresses are permitted, you create a barrier that helps prevent unauthorized devices from accessing your network. This is a direct technological measure that relies on the functionality of the network hardware and software.

In contrast, installing a security camera is more of a physical control as it involves physical security measures to monitor for unauthorized access. Using passwords for accounts can be considered an administrative control aimed at securing access to user accounts, but it doesn't specifically interact with network functionality like MAC address filtering does. Finally, having a security policy for users is largely an administrative measure that guides user behavior rather than a technical control that operates directly on the network.
