Embodiments consistent with the present disclosure provide systems and methods for providing namespace-aware provenance tracking in a containerized environment. In some embodiments, methods for providing namespace-aware provenance tracking in a containerized environment may include monitoring, by one or more custom kernel hooks, event audit records from an OS kernel, wherein the one or more custom kernel hooks extend the functionality of the OS kernel; augmenting the event audit records from the OS kernel with one or more additional namespace aware audit records that include namespace information related to the container associated with event audit records, wherein the namespace information related to the container includes namespace IDs; processing, by an audit reporter, the namespace aware audit records to interpret the namespace IDs contained within the namespace aware audit records; and creating namespace-aware provenance graph that is namespace and container aware based on the namespace aware audit records.

Sound and clear provenance tracking for microservice deployments

A method, apparatus and system for providing security for a container network having a plurality of containers includes establishing a network stack for each of the plurality of containers of the container network, determining network and policy information from active containers, based on a set of pre-determined inter-container dependencies for the plurality of containers learned from the determined network and policy information, configuring container access in the container network to be limited to only containers of the plurality of containers that are relevant to a respective communication, and configuring inter-container traffic in the container network to be directed only from a source container into a destination container in a point-to-point manner such that exposure of the inter-container traffic to peer containers is prevented.

Security for container networks

A network security policy may be implemented at network switches as a set of active packet disposition directives. In a dynamically programmable network, the network switches can be dynamically reprogrammed with new packet disposition directives. A security mediation service permits such dynamic reprogramming as long as the new directives are consistent with the then-current network security policy. The security mediation service evaluates candidate packet disposition directives for conflicts with the currently active security policy, before instantiating the candidate packet disposition directives at the network switches.

Security mediation for dynamically programmable network

An automatic technique for generating signatures for malicious network traffic performs a cluster analysis of known malicious traffic to create a signature in the form of a state machine. The cluster analysis may operate on semantically tagged data collected by connection or session and normalized to eliminate protocol specific features. The signature extractor may generalize the finite-state machine signatures to match network traffic not previously observed.

Semantically-aware network intrusion signature generator

A monitor of malicious network traffic attaches to unused addresses and monitors communications with an active responder that has constrained-state awareness to be highly scalable. In a preferred embodiment, the active responder provides a response based only on the previous statement from the malicious source, which in most cases is sufficient to promote additional communication with the malicious source, presenting a complete record of the transaction for analysis and possible signature extraction.
