<p>A network-enabled electronic system is arranged to determine whether a subsequent DNS request uses a selected domain name of a previous DNS request. A protective action is taken in response to an indication that the subsequent DNS request uses the selected domain name of a previous DNS request. The protective action can include flushing state information that could be used to generate a request using an address that is (maliciously, for example) rebound to the selected domain name.</p> |
