Abstract: Aggregation of cross domain service level indications provide an estimate of available end to end error budget within a service chain of a network system. In some embodiments, service level indications are obtained from a plurality of sub-domains, and aggregated to determine an end to end reliability score. The end to end reliability score is then distributed one or more of the sub-domains. The sub-domains then consider whether to implement a change based on local service level indications as well as the end to end reliability score. In other embodiments, a sub-domain requests approval to implement a change from an error manager. The error manager consults the end to end reliability score to determine whether adequate margin exists in the service chain to allow the change to occur, while still meeting service level objectives of the service chain. The error manager conditionally approves the request based on the determination.

Abstract: A method, computer system, and computer program product are provided for detecting drift in predictive models for network devices and traffic. A plurality of streams of time-series telemetry data are obtained, the time-series telemetry data generated by network devices of a data network. The plurality of streams are analyzed to identify a subset of streams, wherein each stream of the subset of streams includes telemetry data that is substantially empirically distributed. The subset of streams of time-series data are analyzed to identify a change point. In response to identifying the change point, additional time-series data is obtained from one or more streams of the plurality of streams of time-series telemetry data. A predictive model is trained using the additional time-series data to update the predictive model and provide a trained predictive model.

Abstract: In one example, a controller obtains a request to store an object-based storage object and identifies a data sovereignty policy identifier associated with the object-based storage object. The controller queries a data sovereignty policy manager for a data sovereignty policy associated with the data sovereignty policy identifier and obtains, from the data sovereignty policy manager, an indication of the data sovereignty policy. The controller stores the object-based storage object in compliance with the data sovereignty policy.

Abstract: Disclosed are methods, systems, and non-transitory computer-readable media for detecting a presentation attack in a biometric factor domain, such as a multi-factor authentication environment. The methods, systems, and non-transitory computer-readable media comprise analyzing data relevant to a plurality of factors for evaluating whether an authentication attempt by a user is subject to the presentation attack and determining that the authentication attempt is subject to the presentation attack based on analysis of the data from the plurality of factors. The methods, systems, and non-transitory computer-readable media can detect a presentation attack even when the authentication attempt is successful.
