In an edge network, message traffic between the edge network and a core network passes through the edge router. A port scanning attack directed to the network as a whole (core network) potentially emanates from within the LAN. The edge router includes a network throttling device which identifies and mitigates harmful transmissions such that they do not propagate to the core network. The network throttling device has a connection daemon to scan transactions and determine deviant or atypical connection attempts. A session database stores a transaction history representing a window of previous connection attempts. A pattern detector examines the history and looks for malicious behavior. Identified deviant patterns cause a throttler enforcer to limit the triggering user by restricting future connection attempts, thus mitigating harmful effects. Usage, therefore, is not prevented, but resilience to deviant practices is provided. Accordingly, virus propagation via port scanning is mitigated to a safe level and false alarms targeting legitimate activity are minimized.

A target having a controlled utility is provided, as well as a method for changing the utility of the target. The target with controlled utility may be an electronic device, or alternatively, may be a tangible media, such as an optical disc. The controlled target has a change effecting device that is set to a first state, which allows the target to operate according to a first utility. The controlled target also has a receiver for receiving an authorization key, and logic which, responsive to the authorization key, selectively changes the change effecting device to a second state. When the change effecting device is in the second state, the target may operate according to a second utility. In one example, the controlled target has a restricted access key that was stored during manufacture, and the restricted access key is used by the logic in changing the state of the change effecting device. To change the utility of the controlled target, the controlled target is placed proximate to an activation device. The activation device may read an accessible identifier from the controlled target, and retrieve or generate an authorization key that is associated with the target. The activation device may cooperate with a network operation center or other entity to retrieve the authorization key, and to obtain approval to change the utility of the controlled target. If approved, the activation device may then send the authorization code to the controlled target.
