  • Method of unblocking external computer systems in a computer network infrastructure, distributed computer network having such a computer network infrastructure as well as computer program product
    Patent number: 10313305
    Abstract: A method unblocks external computer systems for communication with secured processing computer systems in a computer network infrastructure. An instruction packet is transmitted from an external computer system to a broker computer system within the computer network infrastructure. A random port number of a network port is then generated by the broker computer system, and the random port number is transmitted to a processing computer system. The processing computer system at least temporarily keeps predetermined network ports closed so that access by the external computer system via network by the network ports is prevented, wherein the random port number and/or other information can be interchanged between the processing computer system and the broker computer system, however.
