Critical Infrastructures: Presentation, cyberattacks and protection Mechanisms – A Survey

In recent years, the world has seen great achievements in the development of the infrastructure needed for information and communication technologies, and widespread and growing access to high-speed Internet. Today, governments, businesses, civil society and individuals across the planet are increasingly connected to this vast network. However, the significant growth of the internet has also led to new cybersecurity challenges for the global community. The more interconnected our societies become, the more vulnerable our critical infrastructures are to cyber threats.

It is therefore urgent to find defence methods against these attacks In this article, we present the state of the art in attack methods against critical infrastructures, as well as the defence methods implemented against these attacks.
