Mechanistic Models: Overview of Compartment Models

322
Mechanistic models, a category encompassing both physiological and compartmental modeling, differ from empirical models' approaches to incorporating known factors about the systems being modeled. Empirical models describe data with minimal assumptions, while mechanistic models aim to provide a robust description of available data by specifying assumptions and integrating known factors about the system. Compartmental analysis is a key example of a mechanistic model in pharmacokinetics and...

Open and closed-loop control systems

1.5K
Control systems are foundational elements in automation and engineering. They are broadly categorized into open-loop and closed-loop systems. These classifications hinge on the presence or absence of feedback mechanisms, significantly influencing the system's performance, complexity, and application.
An open-loop control system operates without feedback from the output. It consists of two primary elements: the controller and the controlled process. The controller receives an input signal...

Control systems are everywhere in contemporary society, influencing diverse applications from aerospace to automated manufacturing. These systems can be found naturally within biological processes, such as blood sugar regulation and heart rate adjustment in response to stress, as well as in man-made systems like elevators and automated vehicles. A control system is essentially a network of subsystems and processes that collaboratively convert specific inputs into desired outputs.

Controller Configurations

324
Controller configurations are crucial in a car's cruise control system because they manage speed over time to maintain a consistent pace regardless of road conditions, thereby meeting design goals. In traditional control systems, fixed-configuration design involves predetermined controller placement. System performance modifications are known as compensation.
Control-system compensation involves various configurations, most commonly series or cascade compensation, in which the controller...

Control System Problem01:21

Control System Problem

362
In an open-loop system, such as a basic thermostat, the poles of the transfer function influence the system's response but do not determine its stability. However, when feedback is introduced to form a closed-loop system, such as an advanced thermostat that adjusts heating based on room temperature, stability is governed by the new poles of the closed-loop transfer function.
When forming a closed-loop system, issues can arise if the poles cross into the unstable region, leading to potential...

Area of Science:

  • Cybersecurity
  • Industrial Control Systems (ICS)
  • Network Protocols

Background:

  • Modbus protocol lacks inherent security mechanisms, leaving Industrial Control Systems (ICS) and Supervisory Control and Data Acquisition (SCADA) networks vulnerable to attacks like man-in-the-middle and eavesdropping.
  • Vulnerabilities in Modbus can critically impact essential services, including power, water, and transportation systems, highlighting the urgent need for enhanced security.
  • The Modbus organization has proposed integrating Transport Layer Security (TLS) to bolster security, leveraging X.509v3 digital certificates for authentication and message integrity.

Purpose of the Study:

  • To address the security deficiencies in the Modbus protocol by proposing a new, secure Role-Based Access Control (RBAC) model.
  • To enhance authorization for both client-server interactions and Modbus frames within industrial communication networks.
  • To evaluate the proposed security model's effectiveness against cyber threats and its performance in realistic industrial network environments.

Main Methods:

  • Developed a novel RBAC model incorporating role-based authorization via X.509v3 certificate extensions and message authorization using Unit IDs.
  • Conducted a thorough security analysis to assess the protocol's resilience against various attacks and its adherence to cybersecurity principles like integrity and confidentiality.
  • Implemented and evaluated the proposed design on a GNS3 testbed adhering to the IEC-62443 industrial security standard, measuring latency with different cipher suites.

Main Results:

  • The proposed RBAC model, integrated with TLS, effectively enhances Modbus security, providing robust authentication and message integrity.
  • Security analysis confirmed the model's resistance to common attacks, safeguarding critical cybersecurity pillars.
  • Performance analysis demonstrated the feasibility of the proposed solution in an industrial setting, with latency measurements comparable to existing benchmarks.

Conclusions:

  • The novel RBAC model offers a viable and effective solution for securing Modbus communications in industrial environments.
  • Integrating RBAC with TLS provides a significant security upgrade, protecting critical infrastructure from cyber threats.
  • The proposed security enhancements maintain acceptable performance levels, making it suitable for deployment in real-world industrial control systems.
