Critical infrastructure refers to essential services, systems, facilities, and assets necessary for the proper functioning of society and national economic security. These physical or virtual structures ensure society’s overall well-being, health, and safety. Let’s discuss the importance and security of critical infrastructure.
Critical infrastructure is physical or virtual assets, systems, and networks vital for maintaining society’s economy, health, and safety. It varies slightly from country to country, but the smooth running of infrastructure and its security is important to us all.
Critical infrastructure includes energy, water supply, transportation, communication systems, financial services, healthcare, emergency systems, and defense. While critical industries are more or less the same in all countries, they can vary depending on a nation’s needs, resources, and level of development.
The private sector typically owns critical infrastructure in the United States. However, some are operated by federal, state, or local governments. It is divided into 16 sectors, which strongly depend on one another, so the smooth functioning of interdependent critical structures is essential for the continued operation of society, the economy, and government.
16 critical infrastructure sectors in the United States:
The connection between these 16 interdependent infrastructure systems is important because failure in at least one sector can negatively affect multiple sectors. We’ve seen cyberattacks disrupt the daily operations of critical industries multiple times before. Therefore, companies implement cybersecurity measures to prevent the domino effect on critical infrastructure sectors.
Critical infrastructure evolves and becomes more digitized every day, raising concerns about its cybersecurity challenges. Automated systems reduce the cost of services and improve process efficiency while leaving facilities, sensitive data, and intellectual property open to cyber threats.
Critical infrastructure cybersecurity is a set of programs, protocols, and technologies safeguarding the infrastructure from cybercriminals. Bad actors frequently target infrastructure of national importance, such as the national public health sector, transportation systems, industrial control systems, the government facilities sector, the energy sector, financial services, and other operations vital for the welfare of governments and citizens. We all remember the scandalous ransomware attack on the US Colonial Pipeline that caused the shutdown of the largest fuel pipeline in the US and fuel shortages on the East Coast.
The US Department of Homeland Security (DHS) is responsible for public security. It collaborates continuously with industry sectors, federal agencies, and private organizations to ensure infrastructure security and prevent emerging threats. DHS responsibly analyzes vulnerabilities and monitors and handles security breaches that may affect key industry sectors.
Cyberattacks on infrastructure can have severe consequences for the smooth running of national operations and citizens’ public health or safety. This is why maintaining strong critical infrastructure security is not only crucial for the private sector and federal agencies but is also the responsibility of each of us.
