Critical infrastructure are physical and cyber-based systems that are essential to the operations of the economy and government. Evolving threats to critical infrastructure are mainly pandemics, extreme weather, accidents, or technical failures, acts of terrorism, and cyber threats. Every government in every nation has a responsibility to protect this essential critical infrastructure against natural disasters, terrorist activities and now cyber threats. Critical infrastructure includes the vast network of highways, connecting bridges and tunnels, railways, utilities and building necessary to maintain normalcy in daily life. Transportation, commerce, clean water, and electricity all rely on these vital systems. Vulnerabilities include extreme weather and other natural disasters, pandemics, malfunctions and industrial accidents, hacking, terror attacks, active shooters, foreign influence operation and the investments of potential hostile foreign powers in segments of American infrastructure. Undertaking regular vulnerability assessments (Vas) can help you understand structural weaknesses within your IT infrastructure and protect assets. A comprehensive VA provides extensive knowledge about your digital assets, general risks and safety flaws, potentially decreasing the probability of cyberattacks. SCADA is a centralized system that monitors and controls the entire area. This supervisory system gather data on the process and sends the commands control to the process. The main goal of this supervisory system is to monitor and control equipment in the industrial processes for companies in the public and private sectors. In today’s world, there are SCADA systems almost everywhere. This includes industrial plants, manufacturing, transportation, oil and gas, power distribution, water control etc. SCADA systems are crucial for industrial organizations since they help to maintain efficiency, process data for smarter decisions, and communicate system issues. Successful cyberattacks could paralyze internal processes, cause financial losses and potentially lead to the loss of human lives. There should be some notes that SCADA system vulnerabilities still frequently include unsophisticated bugs like stack and butter overflows, as well as information disclosure and other.
