Cyber Threat Intelligence (CTI) is a rapidly developing field which has evolved in direct response to exponential growth in cyber related crimes and attacks. CTI supports Communication and Information System (CIS)Security in order to bolster defenses and aids in the development of threat models that inform an organization's decision making process. In a military organization like NATO, CTI additionally supports Cyberspace Operations by providing the Commander with essential intelligence about the adversary, their capabilities and objectives while operating in and through cyberspace. There have been many contributions to the CTI field; a noteworthy contribution is the ATT&CK® framework by the Mitre Corporation. ATT&CK® contains a comprehensive list of adversary tactics and techniques linked to custom or publicly known Advanced Persistent Threats (APT) which aids an analyst in the characterization of Indicators of Compromise (IOCs). The ATT&CK® framework also demonstrates possibility of supporting an organization with linking observed tactics and techniques to specific APT behavior, which may assist with adversary characterization and identification, necessary steps towards attribution. The NATO Allied Command Transformation (ACT) and the NATO Communication and Information Agency (NCI Agency) have been experimenting with the use of deception techniques (including decoys) to increase the collection of adversary related data. The collected data is mapped to the tactics and techniques described in the ATT&CK® framework, in order to derive evidence to support adversary characterization; this intelligence is pivotal for the Commander to support mission planning and determine the best possible multi-domain courses of action. This paper describes the approach, methodology, outcomes and next steps for the conducted experiments.

Cyber-physical systems (CPSs) encompass a network of sensors and actuators that are monitored, controlled and integrated by a computing and communication core. As autonomous underwater vehicles (AUVs) become more intelligent and connected, new use cases in ocean production, security and environmental monitoring become feasible. Swarms of small, affordable and hydrobatic AUVs can be beneficial in substance cloud tracking and algae farming, and a CPS linking the AUVs with multi-fidelity simulations can improve performance while reducing risks and costs. In this paper, we present a CPS concept tightly linking the AUV network in ROS to virtual validation using Simulink and Gazebo. A robust hardware-software interface using the open-source UAVCAN-ROS bridge is described for enabling hardware-in-the-loop validation. Hardware features of the hydrobatic SAM AUV are described, with a focus on subsystem integration. Results presented include pre-tuning of controllers, validation of mission plans in simulation and real time subsystem performance in tank tests. These first results demonstrate the interconnection between different system elements and offer a proof of concept.
