Evaluation of Visual Notations as a Basis for ICS Security Design Decisions

For making informed security decisions during the design of industrial control systems (ICS), engineers need to process large amounts of security-relevant information outside their area of expertise. This problem moves the presentation of the security-relevant information into focus: security-relevant engineering information must be presented to security decision-makers in a way that enables them to decide upon security measures to build a defensible system. Visual representations have the potential to effectively convey suchlike information, thus saving the engineers’ brain capacity for the security decision-making. However, research shows that this potential is only realized if the visualizations are carefully constructed for cognitive effectiveness. As a prerequisite for constructing a visual language for security engineering in the future, this paper explores two scientific questions: 1) what are the requirements for visualizing security-relevant engineering information in a way that enables engineers to make security decisions during ICS design? and 2) which existing visual languages meet (parts of) these requirements? The evaluation of existing visualizations reveals that there is a need for an improved, specialized visual language for security engineering that builds upon established engineering visualizations like piping and instrumentation diagrams and network maps, represents all security-relevant information as icons to achieve semantic transparency, and includes filtering mechanisms to reduce the complexity of each single diagram. The paper finishes with defining the main pillars of a future visual language that should allow ICS engineers to quickly capture security-relevant information and guide them through the process of selecting the right security measures to design a defensible ICS.

A Novel Study on Design and Implementation of a Cyber Physical Industrial Control System by Using Cyber Security Techniques

Because of late expansion in arrangement of Cyber-Physical Industrial Control Systems in various basic frameworks, tending to network protection difficulties of these frameworks is essential for guaranteeing their dependability and secure activity in presence of malignant digital assaults. In the ongoing scene that is controlled by innovation and organization associations, it is vital to know what digital protection is furthermore, to have the option to really utilize it. Frameworks, significant documents, information, and other significant virtual things are in danger on the off chance that there is no security to safeguard it. Securing the data have become perhaps of the greatest test in the current day. Whenever we ponder the network protection the primary thing that rings a bell is 'digital violations' which are expanding monstrously step by step. Different Governments and organizations are going to numerous lengths to forestall these digital wrongdoings. Other than different measures digital protection is as yet an extremely large worry to a large number. Towards this end, fostering a testbed to produce ongoing informational indexes for basic foundation that would be used for approval of constant assault recognition calculations are without a doubt profoundly required. This paper investigates and proposes the design and implementation of a cyber-physical industrial control system testbed where the Tennessee Eastman process is simulated in real-time on a PC and the closed-loop controllers are implemented on the Siemens PLCs. Misleading information infusion digital assaults are infused to the created testbed through the man-in-the-center construction where the vindictive programmers can continuously adjust the sensor estimations that are shipped off the PLCs. Moreover, different digital assault location calculations are created and executed continuously on the testbed and their exhibition and capacities are looked at and assessed.

A Cyber-Security Methodology for a Cyber-Physical Industrial Control System Testbed

Due to recent increase in deployment of Cyber-Physical Industrial Control Systems in different critical infrastructures, addressing cyber-security challenges of these systems is vital for assuring their reliability and secure operation in presence of malicious cyber attacks. Towards this end, developing a testbed to generate real-time data-sets for critical infrastructure that would be utilized for validation of real-time attack detection algorithms are indeed highly needed. This paper investigates and proposes the design and implementation of a cyber-physical industrial control system testbed where the Tennessee Eastman process is simulated in real-time on a PC and the closed-loop controllers are implemented on the Siemens PLCs.

Construction of Safety Protection System for Power Industrial Control System and Enhancement Design of Communication Protocol

The safe and stable operation of the power system has always been a common problem related to social stability and economic development in the world. To adapt to the development of “Internet +" and energy Internet, to ensure the information security of the power industrial control side, the power industrial control system Information security raises higher requirements.

Cyber attack detection and mitigation: Software Defined Survivable Industrial Control Systems

Modern Industrial Control Systems (ICS) constitute complex and heterogeneous ‘system of systems’ embracing the numerous advantages of traditional Information and Communication Technology (ICT). The pervasive integration of off-the-shelf ICT into the core of ICS broadened the palette of features and applications, but it also raised new design challenges and exposed ICS to a new breed of cyber-physical attacks. In addition, despite all the security solutions in place, unavoidably, these systems may be compromised. Therefore, survivability, that is, the ability to face malicious actions and faults, becomes a salient feature/requirement in the design of modern cyber-connected ICS. We present a comprehensive solution for ensuring the survival of ICS under malicious activities and faults. We design a Software Defined Networking (SDN) and Network Function Virtualization (NFV) based communication infrastructure particularly tailored to address the communication requirements of ICS. We develop an attack detection and localization algorithm for bidirectional ICS flows, and we design an optimal intervention strategy that embraces the communication and security requirements of industrial applications. Finally, we present intrinsic details on recreating a real-life and emulated test infrastructure. Experimental results demonstrate the solution’s applicability to networked robot control systems.

Analysis of dataflows within industrial control system design

A design of industrial control system is a complex process which is usually divided into specific design steps. Results from antecedent step are generally inputs for the next step and there could be also other influences among steps. So there is a strong dataflow within an automation project especially if the range of designed system is large from the point of view of the signals count, components, variables, alarms and other messages etc. The ability of effective and reliable data transfer between the steps has significant influence on effectivity and quality of the design of an industrial control system. The main goal of the paper is an analysis of the design steps during the industrial control system design, definition of the dataflows between particular steps and description of a concept of automated system for data transmission within the design. The proposed concept is presented and evaluated on pilot industrial control system design project.

Cyber-Security-Aware Network Design of Industrial Control Systems

The pervasive adoption of traditional information and communication technologies hardware and software in industrial control systems (ICS) has given birth to a unique technological ecosystem encapsulating a variety of objects ranging from sensors and actuators to video surveillance cameras and generic PCs. Despite their invaluable advantages, these advanced ICS create new design challenges, which expose them to significant cyber threats. To address these challenges, an innovative ICS network design technique is proposed in this paper to harmonize the traditional ICS design requirements pertaining to strong architectural determinism and real-time data transfer with security recommendations outlined in the ISA-62443.03.02 standard. The proposed technique accommodates security requirements by partitioning the network into security zones and by provisioning critical communication channels, known as security conduits, between two or more security zones. The ICS network design is formulated as an integer linear programming (ILP) problem that minimizes the cost of the installation. Real-time data transfer limitations and security requirements are included as constraints imposing the selection of specific traffic paths, the selection of routing nodes, and the provisioning of security zones and conduits. The security requirements of cyber assets denoted by traffic and communication endpoints are determined by a cyber attack impact assessment technique proposed in this paper. The sensitivity of the proposed techniques to different parameters is evaluated in a first scenario involving the IEEE 14-bus model and in a second scenario involving a large network topology based on generated data. Experimental results demonstrate the efficiency and scalability of the ILP model.

Implementation of a WirelessHART Training System for Upgrading Industrial

Real problem-based learning: specific features of the training method for creation of modern industrial control systems (based on the experience of the european universities participating in TEMPUS MEDIS)

The main aim of the article is to cover the key approaches for improving the problem-based learning (PBL) in the context of students’ training for the design of modern industrial control systems. The study revealed the transformation of PBL into two complementary areas of training: Advanced Problem-Based Learning (APBL) and Real Problem-Based Learning (RPBL). The feature of APBL is the simultaneous study of several interconnected subjects on the base of projects implementation which requires the use of all of these subjects. RPBL complements APBL by training students the missing knowledge and skills through performing real projects for industrial enterprises. It is depicted that in-between transition from PBL to APBL and RPBL the role of teacher is changing. If in PBL the teacher supervises and controls the progress of the project implementation, then in APBL teacher plays the guide role from the formulation of the problem to its solution. In RPBL teacher partially becomes a member of the team carrying out the projects. Specific features of RPBL realization methodology are considered in terms of TEMPUS MEDIS project realization

A metamorphic controller for plant control system design

One of the major problems in the design of industrial control systems is the selection and parameterization of the control algorithm. In practice, the most common solution is the PI (proportional-integral) controller, which is simple to implement, but is not always the best control strategy. The use of more advanced controllers may result in a better eciency of the control system. However, the implementation of advanced control algorithms is more time-consuming and requires specialized knowledge from control engineers. To overcome these problems and to support control engineers at the controller design stage, the paper describes a tool, i.e., a metamorphic controller with extended functionality, for selection and implementation of the most suitable control algorithm. In comparison to existing solutions, the main advantage of the metamorphic controller is its possibility of changing the control algorithm. In turn, the candidate algorithms can be tested through simulations and the total time needed to perform all simulations can be less than a few minutes, which is less than or comparable to the design time in the concurrent design approach. Moreover, the use of well-known tuning procedures, makes the system easy to understand and operate even by inexperienced control engineers. The application was implemented in the real industrial programmable logic controller (PLC) and tested with linear and nonlinear virtual plants. The obtained simulation results conrm that the change of the control algorithm allows the control objectives to be achieved at lower costs and in less time.
