Abstract: Systems, methods, and computer-readable media for gathering network intrusion counter-intelligence. A system can maintain a decoy network environment at one or more machines. The system can identify a malicious user accessing network services through the network environment. Further, the system can receive network service access requests from the user at one or more machines in the network environment and subsequently direct the network service access requests from the malicious user to the decoy network environment based on an identification of the malicious user. The network services access requests can be satisfied with network service access responses generated in the decoy network environment. Subsequently, the system can maintain malicious user analytics based on the network service access requests of the malicious user that are directed to the decoy network environment.

Abstract: Aspects of the disclosed technology provide methods for automatically tuning load-balancer configurations in a network environment. In some implementations, a process of the disclosed technology includes steps for collecting flow records of traffic flow segments at a middle box in a network environment, the traffic flow segments corresponding to one or more traffic flows passing through the middle box, analyzing the flow records to identify one or more traffic patterns in the network environment, and automatically updating a load balancer configuration based on the one or more traffic patterns, wherein updating the load balancer configuration improves at least one traffic flow parameter for at least one of the traffic flows passing through the middle box. Systems and machine-readable media are also provided.

Abstract: Systems, methods, and computer-readable media for flow stitching network traffic flow segments at a middlebox in a network environment. In some embodiments, flow records of traffic flow segments at a middlebox in a network environment are collected. The flow records can include transaction identifiers assigned to the traffic flow segments. Sources and destinations of the traffic flow segments with respect to the middlebox can be identified using the flow records. Further, the traffic flow segments can be stitched together to form a plurality of stitched traffic flows at the middlebox based on the transaction identifiers and the sources and destinations of the traffic flow segments in the network environment with respect to the middlebox. A configuration of the middlebox operating in the network environment can be identified based on the stitched traffic flows at the middlebox in the network environment.

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: The disclosed technology relates to a distributed policy store. A system is configured to locate, in an index, an entry for a network entity, determine, based on the entry, a file identifier for a file containing a record for the network entity and an offset indicating a location of the record in the file. The system is further configured to locate the file in a distributed file system using the file identifier, locate the record in the file using the offset, and retrieve the record.

Abstract: Systems, methods, and computer-readable media for flow stitching network traffic flow segments across middleboxes. A method can include collecting flow records of traffic flow segments at a first middlebox and a second middlebox in a network environment including one or more transaction identifiers assigned to the traffic flow segments. Sources and destinations of the traffic flow segments can be identified with respect to the first middlebox and the second middlebox. Corresponding subsets of the traffic flow segments can be stitched together to from a first stitched traffic flow at the first middlebox and a second stitched traffic flow at the second middlebox. The first and second stitched traffic flows can be stitched together to form a cross-middlebox stitched traffic flow across the first middlebox and the second middlebox. The cross-middlebox stitched traffic flow can be incorporated as part of network traffic data for the network environment.
