Understanding Cyber Security in Critical Infrastructure
Describe critical infrastructure in brief.
In terms of cybersecurity, critical infrastructure can be termed as those complex interconnected ecosystem which includes assets, systems, and networks that gives us the necessary functions which are required for our way of life such as transportation and communication systems, water and power lines, etc.
List common cyber threats to critical infrastructure and what are the different categories of threats?
Major threats to critical infrastructure include cyber warfare, cyber terrorism, cyber crime, and insider threats. Cyber threats in critical infrastructure is mainly classified into three different categories such as natural threats which includes the hazards like earthquake and tsunami, Human-caused threats that includes cyber attacks, rioting, explosions and bombing (also termed as terrrorism).The third category is Accidental and technological threats that includes transportation accidents & failures & infrastructural failures.
List the different challenges faced by cyber security in critical infrastructure.
Major challenges that are faced in critical infrastructure includes Legacy Systems, complexity, constraints related to resources, regulatory compliance issues, and interconnectedness.
Understanding Cyber Security in Critical Infrastructure
The Cybersecurity features of critical infrastructure have rapidly emerged in a digital society and are doing more on online networks. Present-time civilization is largely based on a variety of networks and computer systems in which power supply systems, transportation infrastructure, hospitals, banks, and other institutions of the financial systems operate.
The hard practice of cyber security has another side of vulnerability wherein the dependence on digital technology may lead to a broken cyber defense system becoming one of the targets for cybercriminals. Cybersecurity in critical infrastructure is not only about technicality but it is a matter of historic priority to shrink the chances of economic crisis, public disorder, and national threat.
In this article, we will take a critical look at cyber security as it relates to the essential infrastructures with their challenges, advised methodologies or best practices, and some of the scenarios or examples in the real world where cyber security has been a problem.
