    摘要： A non-transitory, computer-readable medium, comprising instructions that when executed by one or more processors, cause the one or more processors to perform operations that include receiving a request to connect to the wireless access point from a computing device. The request includes a private key. The operations may also include comparing the private key to an index of public keys associated with respective users authorized to connect to the wireless access point, determining that the computing device is authorized to connect to the wireless access point based on the comparison, authorizing the computing device to connect to the wireless access point, encrypting maintenance data associated with one or more industrial automation devices, and transmitting the encrypted maintenance data to the computing device via the wireless access point.

    摘要： Performing multi-layer network discovery of an operational technology (OT) network includes receiving a plurality of discovery data sets, each identifying a respective subset of a plurality of nodes within an OT network having a plurality of network layers, wherein the respective subset of the plurality of nodes for a first discovery data set are disposed within at least two network layers of the plurality of network layers, identifying a set of nodes within the OT network that appear in two or more of the plurality of discovery data sets, generating a holistic discovery data set for the OT network based on the plurality of discovery data sets and the identified set of nodes within the OT network that appear in the two or more of the plurality of discovery data sets, and generating a visualization of the plurality of nodes within the OT network based on the holistic discovery data set.
