Which of the following accurately describes "Denied MAC addresses"?

The concept of "Denied MAC addresses" specifically refers to a list of MAC addresses that are blocked from connecting to a network. This is a common security measure used to control access and restrict unwanted devices from joining a network. By maintaining a list of denied MAC addresses, administrators can ensure that only authorized devices are permitted access, enhancing the overall security posture of the network.

This method is often implemented alongside other security practices, such as whitelisting allowed MAC addresses, to create a comprehensive access control strategy. By focusing on denied MAC addresses, organizations can proactively identify and mitigate potential security threats from unauthorized devices.
