  • Publication number: 20210120001
    Abstract: The present disclosure pertains to systems and methods of restricting access to devices utilizing tokens. In some embodiments, a system may include a user requesting a token, ensuring the user requesting a token has the permission to request the token and is not the user approving the token. In some embodiments, the system may include the user granting the token, wherein the user granting the token is not the user receiving the token. The system ensures that the user accessing the device has the permission to access the device. Additionally, the system decreases the opportunities for insider attacks and increases the resistance to credential theft attacks. Further, the system increases the accountability for changes and the ability to review changes.

  • Publication number: 20210119795
    Abstract: Systems and methods are disclosed herein relating to the secure configuration of intelligent electronic devices. Intelligent electronic devices are used in electric power generation and transmission systems for protection, control, automation, and/or monitoring of equipment. The use of tokens and token-based digital signatures in the configuration process of intelligent electronic devices reduces the likelihood of malicious acts or unintended errors. Tokens distributed to engineers, technicians, intelligent electronic devices, computing devices, and/or software decrease the likelihood of errors being introduced in the configuration process.

  • Patent number: 10862825
    Abstract: Systems and methods are described herein for token-based access to an intelligent electronic device (IED) resource in a power delivery system. A token server and an IED resource may be communicatively connected via a communication network. The token server may generate a token associated with access privileges to one or more IED resources. The token server associates an access duration time with the generated token. The user presents the IED resource with the token as part of an access attempt. The IED resource grants access at a first time defined with reference to the device uptime of the IED resource until a second time defined with reference to the device up time. The difference between the first time and the second time corresponds to the access duration time of the token.

  • Patent number: 10298498
    Abstract: The present disclosure pertains to systems and methods to identify high-priority traffic within a software defined network (“SDN”) and to route such traffic through physically distinct communication paths. Such routing may help to reduce network congestion faced by high-priority traffic and increase the reliability of transmission of such data. Certain embodiments may further be configured to generate a failover communication path that is physically distinct from a primary communication path. Still further, certain embodiments may be configured to suggest enhancements to a network that may improve a reliability criterion.

  • Patent number: 9923779
    Abstract: The present disclosure pertains to systems and method for configuration of communication flows in a software defined network (“SDN”). In one embodiment, a system is operable to configure a communication flow between a first host and a second host. A mode selection subsystem is configured to cause a plurality of network devices in a network connecting the first communication host and the second communication host to transition between an open mode and an SDN operating mode. In the open mode, the network devices may discover a communication path between the first host and the second host. An analysis subsystem may receive information from the plurality of network devices information about the discovered path, and a topology discovery subsystem may be configured to create a communication flow corresponding to the discovered path. The communication flow may allow communication between the first host and the second host in the SDN operating mode.

  • Patent number: 9769060
    Abstract: The present disclosure pertains to systems and methods for simulating data packet routing within a software defined network (“SDN”), visualizing the results of the simulation, and permitting a user to search the resulting simulation. In one specified embodiment, a system may receive from a user a simulation parameter associated with a packet to be simulated in the SDN. A packet based on the at least one simulation parameter may be generated. A response of the SDN to the packet may be simulated by identifying applicable traffic routing rules and identifying a subsequent destination based on the applicable traffic routing rules. A record of the subsequent destination may be added to the simulation result, and the process may continue until a terminating condition is satisfied.
