Systems and methods for rule-based anomaly detection on IP network flow
A system to detect anomalies in internet protocol (IP) flows uses a set of machine-learning (ML) rules that can be applied in real time at the IP flow level. A communication network has a large number of routers equipped with flow monitoring capability. A flow collector collects flow data from the routers throughout the communication network and provides them to a flow classifier. At the same time, a limited number of locations in the network monitor data packets and generate alerts based on packet data properties. The packet alerts and the flow data are provided to a machine learning system that detects correlations between the packet-based alerts and the flow data to thereby generate a series of flow-level alerts. These rules are provided to the flow time classifier. Over time, the new packet alerts and flow data are used to provide updated rules generated by the machine learning system. |

Trusted network detection
Approaches for processing network requests based upon the perceived trustworthiness of the network. A software component renders a judgment, based on a policy that weighs one or more factors, about whether a network accessible to a device should be trusted.

The identity provider determines if the user meets the desired class level and provides various information related to the authentication. When the user attempts to access a second service provider that is associated with the same identity provider, the second service provider accesses the identity provider and determines that the user was recently authenticated. The identity provider then transmits the relevant information regarding the authentication process to the second service provider, which can then allow or deny the user access to the second service provider. |

Deploying operators of a streaming application based on physical location attributes of a virtual machine
A streams manager monitors operator performance of a streaming application to determine when the performance of an operator needs to be improved or optimized. The streams manager in conjunction with a cloud manager automatically determines one or more preferred virtual machines in a cloud with a specified streams infrastructure that best meet the needs of the underperforming operator or application component based on physical location attributes of the preferred virtual machines. The cloud manager determines the physical location attributes of the candidate virtual machines. The streams manager or the cloud manager can then determine a preferred virtual machine of the candidates to deploy the operator based on the physical location attributes. The streams manager then modifies the flow graph so one or more operators of the streaming application are deployed to a preferred virtual machine determined according to the physical location attributes of the preferred virtual machine. |
