The disclosed technology relates to a network agent for reporting to a network policy system. A network agent includes an agent enforcer and an agent controller. The agent enforcer is configured to implementing network policies on the system, access data associated with the implementation of the network policies on the system, and transmit, via an interprocess communication, the data to the agent controller. The agent controller is configured to generate a report including the data and transmit the report to a network policy system.

Network agent for reporting to a network policy system

Aspects of the subject technology relate to a system configured to receive a set of network snapshot segments from an output stream of a stream processing service, compile the set of network snapshot segments from the set of messages into a first network snapshot and a second network snapshot, and compare the first network snapshot and the second network snapshot to identify a difference between the first network snapshot and the second network snapshot.

Mechanism for identifying differences between network snapshots

The disclosed technology relates to a network agent for generating platform specific network policies. A network agent is configured to receive a platform independent network policy from a network policy system, determine implementation characteristics of the network entity, generate platform specific policies from the platform independent network policy based on the implementation characteristics of the network entity, and implement the platform specific policies on the network entity.

Aspects of the disclosed technology relate to ways to authenticate customer/subscriber access to a policy update stream. A process of the technology can include steps for instantiating a network monitoring device in response to a request, the request comprising one or more configuration parameters for the network monitoring device, and receiving a first certificate from the network monitoring device, wherein the first certificate is based on the one or more configuration parameters. In some aspects, the steps can further include sending the first certificate to a processing pipeline for authentication, wherein the processing pipeline is configured to authenticate the first certificate based on a second certificate received by the processing pipeline from the network monitoring device. Systems and machine readable media are also provided.

Secure publishing for policy updates

Disclosed is a system configured to receive a set of network snapshot segments from an output stream of a stream processing service, compile the set of network snapshot segments from the set of messages into a first network snapshot and a second network snapshot, and compare the first network snapshot and the second network snapshot to identify a difference between the first network snapshot and the second network snapshot.

Aspects of the subject technology relate to a system configured to receive, from a stream processing service, a first network snapshot segment. The first network snapshot segment is associated with metadata that is used to determine that at least one additional network snapshot segment associated with the output stream has not been previously received. The system is configured to request, from the stream processing service, the at least one additional network snapshot segment and generate a first network snapshot by compiling the first network snapshot segment and the at least one additional network snapshot segment.

Mechanism for facilitating efficient policy updates

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.
