Critical Infrastructure Cybersecurity: Full Definition

We live in a digital world full of cyber threats. So, public and private sectors must secure critical infrastructure cybersecurity.

Read on to learn more.

Critical Infrastructure Cybersecurity Defined

But first, let us define what critical infrastructure is.

Critical infrastructure refers to the computer data, systems, and networks of the United States. But, these are not just ordinary computer assets. Why?

These assets are vital in the US. So, without these, it will affect security, economic security, health, or safety.

Moreover, there are so many threats and vulnerabilities in the digital landscape. In fact, the Department of Homeland Security points out this need.

So, DHS continues to secure the critical infrastructures. They do this by working with other industries, federal agencies, and private companies.

Furthermore, they outlined a plan for public and private sectors to protect critical infrastructure in the US.

But, what are the top sectors in the United States that protect critical infrastructure cybersecurity?

Top Sectors of Critical Infrastructure Cybersecurity

Energy Services Sector

The energy sector enables the US economy. Without a secure energy sector, it will compromise the citizens’ welfare.

For example, Dragonfly 2.0 hackers targeted US energy companies. The result? They hacked the industrial control maps that power the energy grid of the US.

Dams Sector

The Dams sector controls water services and maintenance in the US. Also, these services include:

  • hydroelectric power
  • agricultural systems
  • inland mass transportation
  • recreation

In 2016, a cyberattack hit the Rye Brook Dam in New York, US. So, the hackers accessed the control systems of the dam.

Also, if not responded quickly, they would have released the water behind the dams. Fortunately, it was prevented.

Financial Services Sector

The financial services sector protects the economy of the US. But, it is one of the most attacked sectors.

In addition, the Equifax credit breach affected 44% of the US population. It also stole more than 140 million records from the finance sector.

Nuclear and Waste Sector

The nuclear sector provides not just electricity to millions of Americans. It also gives medical isotopes. And researchers use these isotopes to treat cancer.

Moreover, it became a major target for cyber threats. Experts even suggest that it can lead to dangerous attacks. Where hackers can get full access to the infrastructure.

Food and Agriculture Sector

The Food and Agriculture sector composes of the following:

  • 2.1 million farms
  • 935,000 restaurants
  • over 200,000 manufacturing facilities

Additionally, this sector uses connected devices with big data. So, they are at risk for hackers.

Unfortunately, a survey states that 87% of farmers have no response plan prepared.

Water Systems Sector

The water systems sector ensures the supply of water for US citizens. So, it is essential for general wellbeing.

But in 2016, hackers rack up water bills. They also took control of the water authority. So, the damages round up to $100,000.

Healthcare and Public Sector

This sector secures US citizens’ health and safety. Yet, it’s one of the main targets for data breaches. Why?

It has so many sensitive data and personal information. Thus, they continue to take incident response plans.
