Abstract:

Critical infrastructure is a term to define the network of crucial assets for the functioning of a society and modern economies. The complexity of critical infrastructures and the ability to connect smart devices to these networks make them more vulnerable to cyberattacks. One of the cutting events pointing out gaps and importance of the cyber resilience in the nation's infrastructure systems, including Industrial Control Systems (ICS), was the discovery of Stuxnet in 2010, a malicious computer worm attacking Iranian nuclear facilities. The vulnerability of cyber systems was further revealed b

Abstract:

<p>Cyber counterintelligence (CCI) could be the United States' best defense against Chinese cyber aggression of Critical Infrastructure and Key Resources (CIKR). The need to defend CIKR is essential to public safety and national defense. As technology evolves and continues to march towards the inevitable connectedness that brings systems in sync with one another, the United States becomes more vulnerable. Of the 16 total sector specific areas of United States’ assets, the Communications and Information Technology (IT) sectors are constantly under attack from threats both foreign and dome

Abstract:

Cyber-attack simulation is a suitable method used for assessing the security ofnetwork systems. An attack simulation advances step-wise from a certain systementry-point to explore the attack paths that lead to dierent weaknesses inthe model. Each step is analyzed, and the time to compromise is calculated.Attack simulations are primarily based on attack graphs. The graphs areemployed to model attack steps where nodes can represent assets in the system,and edges can represent the attack steps. To reduce the computational cost associatedwith building an attack graph for each specic system, domain

Abstract:

Critical infrastructures include sectors such as energy resources, finance, food and water distribution, health, manufacturing and government services. In recent years, critical infrastructures have become increasingly dependent on ICT; more interconnected and are often, as a result, linked to the Internet. Consequently, this makes these systems more vulnerable and increases the threat of cyber-attack. In addition, the growing use of wireless networks means that infrastructures can be more susceptible to a direct digital attack than ever before. Traditionally, protecting against environmental

Complex cyber-physical systems have become fundamental to modern society by effectively providing critical services and improving efficiency in various domains. Unfortunately, as systems become more connected and more complex, they also can become more vulnerable and less robust. As a result, various failure modes become more common and easily triggered from both unanticipated and malicious perturbations. Research has been conducted in the area of vulnerability analysis for cyber-physical systems, to assist in locating these possible vulnerabilities before they can fail. I present two case st

Abstract:

Cyber-physical systems (CPSs) are systems that integrate physical elements with a cyber layer that enables sensing, monitoring, and processing the data from the physical components. Examples of CPSs include autonomous vehicles, unmanned aerial vehicles (UAVs), smart grids, and the Internet of Things (IoT). In particular, many critical infrastructure (CI) that are vital to our modern day cities and communities, are CPSs. This wide range of CPSs domains represents a cornerstone of smart cities in which various CPSs are connected to provide efficient services. However, this level of connectivity

The modernization of the power grid has seen an increase in the integration and incorporation of computing and communication elements, creating an interdependence of both physical and cyber assets of the power grid. The fast-increasing connectivity has transformed the grid from what used to be primarily a physical system into a Cyber- Physical System (CPS). The physical elements within a power grid are well understood by power engineers; however, the newly deployed cyber aspects are new to

Computational power of mobile devices has been continuously improving in the recent years. One of the benefits which it brings, is feasibility of new kinds of distributed systems, such as Ensemble-Based Component Systems (EBCS). For practical reasons, EBCS systems are usually tested using simulations before being released. However, it can be difficult to interpret the simulation output, as it is usually contained in XML format, which is more suited to be read by machines than by people. We provide a visualizing application, which creates a graphical representation of such a simulation output.
