Abstract: A method 300 of generating invariants for distributed attack detection on a cyber-physical system 100 having a number of system components is provided. In a described embodiment, the method 300 includes deriving design invariants at 310 based on system design of the cyber physical system 100 including physical specifications of the system components, obtaining operational data of the cyber physical system at 320 including operational attributes of the system components, generating operational invariants from the obtained operational data at 330, and correlating the operational variants with the design invariants at 340 to generate an integrated set of invariants for detecting distributed cyber attacks of the cyber physical system 100.

Abstract: A method and apparatus for determining an identity of an unknown Internet-of-Things (IoT) device in a communication network is disclosed. The method includes the steps of receiving network traffic generated by the unknown IoT device, extracting device network behavior from the generated network traffic, and determining the identity of the unknown IoT device from a list of known IoT devices by applying a selected machine learning based classifier from a set of machine learning based classifiers to analyze the device network behavior. Each machine learning based classifier of the set is trained by a dataset including a plurality of features representing network behavior of a respective known IoT device from the list and the known IoT device's identity. The plurality of features is associated with the corresponding device network behavior of the generated network traffic.
