“…Other AI techniques, such as propositional logic, have been adopted in the area of critical infrastructure protection. In [169], the authors proposed a logic-based framework to enforce security policies for system authorization in SCADA systems, because the authentication process in this environment requires complex mapping between user privileges and system rules. In such a framework, rules are distributed across system nodes, so that they can derive the sets of actions the user can perform on each node.…”

Cybersecurity is a fast-evolving discipline that is always in the news over the last decade, as the number of threats rises and cybercriminals constantly endeavor to stay a step ahead of law enforcement. Over the years, although the original motives for carrying out cyberattacks largely remain unchanged, cybercriminals have become increasingly sophisticated with their techniques. Traditional cybersecurity solutions are becoming inadequate at detecting and mitigating emerging cyberattacks. Advances in cryptographic and Artificial Intelligence (AI) techniques (in particular, machine learning and deep learning) show promise in enabling cybersecurity experts to counter the ever-evolving threat posed by adversaries. Here, we explore AI's potential in improving cybersecurity solutions, by identifying both its strengths and weaknesses. We also discuss future research opportunities associated with the development of AI techniques in the cybersecurity field across a range of application domains.

“…The references that wind up this manuscript should be complemented by many more items related to time modeling, namely those that were the original source for the paradigm presented; nevertheless they can be retrieved entirely from the article (Sveda, 2013). Also, some technicalities related to SCADA applications are dealt in more detail by (Rysavy and Rab and Halfar and Sveda, 2012) and (Rysavy and Rab and Sveda, 2013).…”

This paper discusses the role of time in industrial cyber-physical applications of information systems using SCADA as a representative example. It restates the basics of the notion of time, which is important not only in general but particularly in enterprise domain, and focuses on industrial applications. Also, the manuscript brings SCADA concepts and relates them to cyber-physical system architectures. The case study demonstrates some time-related techniques in frame of a simple but real-world application.

“…However, with the advances in both hardware and software over time, there are additional requirements important for its applicability of contemporary SCADA systems: extensive and elaborate SCADA model, reusability, extensiblity, easy adaptation to user demands, crossplatform and secured operation. [5] [6] [7] Contemporary SCADA systems on the modern market need to support the handling of millions of data points (part telemetered, part derived) in a networked, real-time environment. Data acquisition and primary data processing is always done in a centralized fashion due to architectural limitations, and then the concentrated values in the real-time database counting several million data points are distributed to achieve high-availability.…”

SCADA solutions are under a high flux to shift their focus from process control of a limited set of industrial plants to the control of large-scale system of systems. This is in par with the recent proliferation of ubiquitous/pervasive computing paradigm mostly embodied as Internet of Things (IoT). In a traditional setup, a whole system is only partially covered by SCADA data points; therefore, complex simulation is required to fit the missing measurements, hence, buttress decision support scenarios. This usually entails a fully integrated and centralized approach, where SCADA infrastructure needs to hold and distribute data, both collected and calculated. It leads to the increase of load on a supporting real-time database, which hosts millions of data points. It is a challenge that a traditional SCADA design (based on a shared memory database and competing processes), cannot fulfill in real-time. This paper proposes an alternative approach of an architecture and basic functionality of a SCADA system. The proposed architecture targets distributed SCADA systems that can be used to supervise and control large-scale distributed industrial or infrastructural systems. Strategic data organization and segmentation are introduced, so that the acquired data can be efficiently distributed throughout the system. The proposed architecture pushes forward a peer-to-peer node structuring scheme, where an autonomous node supervises and controls only subsets of the system. Nodes collaborate to establish a unified view of the entire system. The proof of the concept implementation has proven to be able to manage significantly more data points in a distributed fashion than a centralized variant.
