Port security: A set of rules and parameters applied on a network switch port to secure the network by controlling who can connect to it and limiting the number of MAC addresses allowed on a single port. This feature can prevent unauthorized access by disabling the port or sending an alert if an unexpected device is detected. It helps protect the network from threats like MAC flooding, which can lead to a denial of service.
