  • receiving, by a computing system provisioned with a plurality of packet-filtering rules, a first packet and a second packet;

    responsive to a determination by the computing system that the first packet comprises data corresponding to a transport layer security (TLS)-version value for which one or more packet-filtering rules of the plurality of packet-filtering rules indicate packets should be forwarded toward their respective destinations, forwarding, by the computing system, the first packet toward its destination; and

    responsive to a determination by the computing system that the second packet comprises data corresponding to a TLS-version value for which the one or more packet-filtering rules indicate packets should be blocked from continuing toward their respective destinations, dropping, by the computing system, the second packet.
