摘要： 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.

摘要： The present disclosure pertains to systems and methods of monitoring communication devices and communication links in a software-defined network (SDN). Network packets may be colored or tagged for routing to a packet analyzer. A VLAN bitmask may be added to a packet to identify the packet for inspection and, optionally, provide origin information identify a switch and/or port of origin. Port mirroring may be utilized and/or eventual routing of network packets to their original destination may ensure that network traffic is not disrupted. In one example, a most significant bit of a VLAN bitmask may be used by a match rule to identify packets intended for a packet analyzer without regard to original packet routing instructions and/or packet content.

摘要： 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.

摘要： The present disclosure pertains to systems and methods for establishing communication with a remote communication device in a software defined network (SDN) during time when an SDN controller is unavailable. In one embodiment, a local communication device may be configured to receive a plurality of data flows from an SDN controller and to store the plurality of data flows in a persistent data memory. The device may generate a unique identifier for the local communication device that is transmitted to a remote communication device. Following a disruption the results in the SDN controller being unavailable, the local communication device may recover into a default configured state based on the plurality of data flows in the persistent data memory. The local communication device may then transmit the unique identifier to the remote communication device after the disruption to begin a process of reestablishing communication with the remote communication device.
