Industrial Cybersecurity

By: Pascal Ackerman

Overview of this book

With industries expanding, cyber attacks have increased significantly. Understanding your control system’s vulnerabilities and learning techniques to defend critical infrastructure systems from cyber threats is increasingly important. With the help of real-world use cases, this book will teach you the methodologies and security measures necessary to protect critical infrastructure systems and will get you up to speed with identifying unique challenges.Industrial cybersecurity begins by introducing Industrial Control System (ICS) technology, including ICS architectures, communication media, and protocols. This is followed by a presentation on ICS (in) security. After presenting an ICS-related attack scenario, securing of the ICS is discussed, including topics such as network segmentation, defense-in-depth strategies, and protective solutions. Along with practical examples for protecting industrial control systems, this book details security assessments, risk management, and security program development. It also covers essential cybersecurity aspects, such as threat detection and access management. Topics related to endpoint hardening such as monitoring, updating, and anti-malware implementations are also discussed.

Chapter 9. ICS Computer Security

In this chapter, we will be exploring the computer security layer of the defense-in-depth model. At this point, the stacking of security measures becomes more noticeable. For example, in the previous chapter, we installed network perimeter firewalls to restrict certain network connections from getting established across security boundaries by blocking the corresponding network ports at the network perimeter. In this chapter, we will add backup security controls (additional layers of defense) by applying endpoint hardening and configuring a host-based firewall policy.

This chapter will cover the following topics:

  • Patch management
  • Anti-malware software
  • Endpoint protection software
  • Endpoint hardening
  • Application whitelisting software
  • Monitoring and logging
  • Configuration/change management—software updates
