Abstract: Detecting network anomalies is provided. An amount of change between aggregate representational error data and number of hops data and average travel time data is determined based on comparing the aggregate representational error data that indicate expected network behavior for a network regarding data packet number of hops and average travel time in the network with the number of hops data and the average travel time data that indicate changes in the data packet number of hops and average travel time in the network. It is determined whether the amount of change between the aggregate representational error data and at least one of the number of hops data and the average travel time data is greater than a maximum amount of change threshold level. In response to determining that the amount of change is greater than the maximum amount of change threshold level, an anomaly is detected in the network.

Abstract: An embodiment establishes a network model based at least in part on network data received from a network, wherein the network data comprises device data and certificate data. The embodiment samples the network to receive a network data sample. The embodiment compares the network data sample to the network model to determine whether an anomalous amount of devices is present in the network. The embodiment compares the network data sample to the network model to determine whether an anomalous amount of certificates is present in the network. The embodiment identifies a device population anomaly upon a determination that an anomalous amount of devices and/or an anomalous amount of certificates is present in the network.

Abstract: One embodiment of the invention provides a method for reverse proxy inspection (RPI) of encrypted traffic in an edge-based network. The method comprises sharing a first certificate from an RPI instance to an edge-based network gateway. The first certificate is issued to the RPI instance. The method further comprises receiving, at the RPI instance, an encrypted message with an initial layer of encryption and a subsequent layer of encryption. The initial layer is encrypted using a second certificate issued to an edge-based network device. The subsequent layer is encrypted using the first certificate. The method further comprises, at the RPI instance, authenticating the first certificate, and decrypting the subsequent layer using the first certificate, resulting in the encrypted message with the initial layer intact. The method further comprises, at the RPI instance, inspecting the encrypted message, and forwarding the encrypted message to a centralized hub.

Abstract: In some examples, workflow-based dynamic data model and application generation may include ascertaining, for an application that is to be generated, a plurality of fields that are declared. Based on the plurality of declared fields, a data model may be generated. The data model may include a plurality of application programming interface (API) keys associated with the plurality of declared fields. Based on the data model, a mapping file may be generated to map a plurality of APIs that are to be invoked relative to the API keys. Based on the data model and the mapping file, the application may be generated.
