Abstract: An example method includes detecting, using sensors, packets throughout a datacenter. The sensors can then send packet logs to various collectors which can then identify and summarize data flows in the datacenter. The collectors can then send flow logs to an analytics module which can identify the status of the datacenter and detect an attack.

Abstract: The disclosed technology relates to intent driven network management. A system is configured to maintain an inventory store comprising records for a set of network entities in a network, wherein each network entity in the set of network entities is associated with a record in the inventory store. The system receives a user intent statement comprising an action and a flow filter representing network data flows on which the action is to be applied and queries, based on the flow filter, the inventory store to identify a plurality of network entities in the set of network entities to which the user intent statement applies. The system generates a plurality of network policies that implement the user intent statement based on the plurality of network entities and the action and enforces the plurality network policies.

Abstract: A method provides for receiving network traffic from a host having a host IP address and operating in a data center, and analyzing a malware tracker for IP addresses of hosts having been infected by a malware to yield an analysis. When the analysis indicates that the host IP address has been used to communicate with an external host infected by the malware to yield an indication, the method includes assigning a reputation score, based on the indication, to the host. The method can further include applying a conditional policy associated with using the host based on the reputation score. The reputation score can include a reduced reputation score from a previous reputation score for the host.

Abstract: A application and network analytics platform can capture telemetry (e.g., flow data, server data, process data, user data, policy data, etc.) within a network. The application and network analytics platform can determine flows between servers (physical and virtual servers), server configuration information, and the processes that generated the flows from the telemetry. The application and network analytics platform can compute feature vectors for the processes. The application and network analytics platform can utilize the feature vectors to assess various degrees of functional similarity among the processes. These relationships can form a hierarchical graph providing different application perspectives, from a coarse representation in which the entire data center can be a “root application” to a fine representation in which it may be possible to view the individual processes running on each server.

Abstract: Flow data can be augmented with features or attributes from other domains, such as attributes from a source host and/or destination host of a flow, a process initiating the flow, and/or a process owner or user. A network can be configured to capture network or packet header attributes of a first flow and determine additional attributes of the first flow using a sensor network. The sensor network can include sensors for networking devices (e.g., routers, switches, network appliances), physical servers, hypervisors or container engines, and virtual partitions (e.g., virtual machines or containers). The network can calculate a feature vector including the packet header attributes and additional attributes to represent the first flow. The network can compare the feature vector of the first flow to respective feature vectors of other flows to determine an applicable policy, and enforce that policy for subsequent flows.

Abstract: The technology visualizes data flows within a datacenter in an interactive hierarchical network chord diagram. Based on analyzed data describing data flows, a portion of the data flows that originate at the same first endpoint and terminate at the same second endpoint can be grouped. Subsequently, the dataflow monitoring system displays an interactive hierarchical network chord diagram to include a chord with a first endpoint and a second endpoint. The chord represents the grouped portion of data flows that originate at the same first endpoint and terminate at the same second endpoint. Upon receiving a selection of the chord or the first endpoint of the chord, the dataflow monitoring system expands the grouped portion of the data flows into a more granular representation of the network.
