Internet of Things (IoT) Cybersecurity Techniques

Securing Internet of Things and Critical infrastructure Industrial Control (ICS) Systems

Topic: Hardware
Aamir Lakhani

Welcome to the connected world. Everything from our smartwatches, refrigerators, thermostats, and clocks are connected to the Internet. Recent security vulnerabilities and attacks have proven these are the some of the most vulnerable assets and most valuable targets to attackers.

Surprisingly, IoT devices are used extensively in critical infrastructure from smart meters, grids, water plants, and many other government services. The Department of Homeland Security defines 16 sectors of industry that are so vital, that their incapacitation would affect a country’s security, economy, and public safety. These industries have been the targets of cyberattacks.

Hackers are trying to gain notoriety as well as nation states attempting to harm and attack IoT devices that are now used in all industries and sectors. This course will introduce you to cybersecurity concepts and concerns around major critical infrastructure components and IoT attacks. We will examine how attackers take advantage of IoT and Critical Infrastructure to attack organizations, spread ransomware, and cause havoc to organizations. You will gain an understanding of the motivation behind the attackers and learn how they exploit systems.

We will then use cybersecurity and Pen Testing tools to explore vulnerabilities in these systems and how they can be exploited. You will understand how hackers find and attack IoT systems for enterprise, consumer, and even government industrial control systems by exposing their vulnerabilities.

Lastly, we will review the major cybersecurity defense strategies that cybersecurity practitioners use to defend IoT devices without compromising the availability and functionality of critical infrastructure devices.

What you'll learn-and how you can apply it

  • Learn the fundamentals of IoT Cybersecurity systems and their components
  • Learn about the ICS/SCADA threats and the threat actors
  • Get an inside look at the most popular and successful attacks against IoT devices.
  • Review tools and techniques you can use to test and audit IoT devices across different industries systems
  • Gain an understanding of theoretical defensive frameworks used to protect IoT and critical infrastructure.
  • Explore tools you can use to implement in your environment to secure IoT systems.

This training course is for you because...

This course is intended for cybersecurity professionals who want to get exposed to critical infrastructure OT (operational security) and cybersecurity. It will give you an understanding and introduction around one of the most concerning topics in cybersecurity today.


A solid understanding of cybersecurity and familiarity of IoT devices and basic concepts.
