Abstract
Cyberattacks, which consist of exploiting security vulnerabilities of computer networks and systems for any kind of malicious purpose (e.g., extortion, data steal, assets hijacking), have been continuously increasing worldwide in recent years. Cyberspace appears today as a new battlefield, along with physical world scenarios (land, sea, air, and space), for the organizations defence and security. Besides, by the fact that attacks from the physical world may have significant implications in the cyber world and vice versa, these dimensions cannot be understood independently. However, the most common intelligence systems offer an insufficient situational awareness exclusively focused on one of these decision spaces. This article introduces HYBINT, an enhanced intelligence system that provides the necessary decision-making support for an efficient critical infrastructures protection by combining the real-time situation of the physical and cyber domains in a single visualization space. HYBINT is a real cross-platform solution which supplies, through Big Data analytical methods and advanced representation techniques, hybrid intelligence information from significant data of both physical and cyber data sources in order to bring an adequate hybrid situational awareness (HSA) of the cyber-physical environment. The proposal will be validated in a detailed scenario in which HYBINT system will be evaluated.
Highlights
This paper introduces HYBINT, a real and advanced hybrid intelligence system for critical infrastructures protection
RTIR) responsible to gather significant data related to the cyber environment, a Sensor Observation Service (SOS) server which exposes the necessary services to feed and retrieve information from all the physical assets simulated in the scenario [71], and a common computer in order to allow, through accessing to HYBINT platform, the system administrator to perform manual insertions
Significant data collected from heterogeneous cyber and physical data sources are processed through latest analytical procedures in order to produce real-time intelligence information which is shown, through advanced representation techniques, in a single visualization space
Summary
The accelerated technological development arose in the last decade has reached most of the society areas allowing organizations to be more efficient by expanding their operational spectrum to cyberspace and overcoming the physical limitations of markets and borders This recent transformation is mostly leaded by the Information and Communication Technologies [1], where hot research fields such as Big Data [2, 3], Artificial Intelligence [4], or Internet of Things (IoT) [5, 6] are already heading this new paradigm in which physical world (land, sea, air, and space) merges with cyberspace producing a hybrid environment where physical and cyber entities are linked together [7] (Figure 1). Both the current scenario and the present proposal are introduced; secondly, the oeuvres taken as main references and the motivation of this work are described; after that, HYBINT system architecture and the functionalities of each of its modules are explained in detail; a validation scenario and the obtained results are presented; and main conclusions and future works are exposed
