Patent attributes
A system for securing control plane traffic in a sliced communication network that is adapted to run a plurality of network functions includes a plurality of security guards, each placed at an edge of an internal security zone, wherein the internal security zone is formed by grouping one or more network functions. Each security guard is configured to receive an incoming message from a requestor external to corresponding internal security zone and validate the extracted information against each other, and against a service specification policy for the communication network, and against threat intelligence analytics data. Each security guard is configured to compute one or more risk scores indicating risk perception or incidence of attack for its associated internal security zone and to initiate one or more attack preventive measures if a computed risk score exceeds a predetermined threshold. such as modifying or correcting or dropping the incoming message.
