Introduction Protecting a nation’s critical infrastructure refers to the need to protect key infrastructures like food and cultivation. The government in every region is responsible for protecting these basic infrastructures from destruction by natural calamities, terrorism, and in this current world, from cyber-attacks. Supervisory Control and Data Acquisition (SCADA) systems are a component of the critical infrastructure and are affected by the Stuxnet worm. SCADA is a system that enabled organizations to document occurrences in a log file, relate with devices straightaway and manage industrial processes remotely. Stuxnet is a computer worm that was programmed to delve into industrial systems and inquire from the host’s specific information (Abou, 2021). Stuxnet takes advantage of the vulnerabilities of systems in the nation and can replicate itself to perform complex actions in a computer without any human intervention. The United States (US) is faced with security challenges in protecting its critical infrastructure since it is vulnerable to and has been impacted by the Stuxnet worm. The government sectors can employ some methods to mitigate the threats and vulnerabilities. The Impact and the Vulnerability of the SCADA/Stuxnet Worm The US is currently vulnerable to cyber-attacks due to the presence of Stuxnet worms in its critical infrastructure essential to contemporary society. The vulnerability results from the US depending on SCADA systems to control vital and complex functional processes, yet the system is prone to Stuxnet worm. The extensive adoption of these systems arose from the need to manage important commercial systems in an economical way to support the growth of demand for commodities and services in the current society. Industrial complexity is the reason for the need for SCADA systems in the US that are prone to cyber-attacks; this makes them vulnerable to Stuxnet malware. The requirement for periodic updates is among the typical susceptibilities of SCADA since the updates are done via the internet, thus creating an avenue for intruders. The ease of handling updates surpassed security priorities due to many SCADA systems being integrated with other industrial systems in the US, which led to more vulnerabilities. The nation has been overly dependent on these systems, exposing its critical infrastructures to cyber-attacks. Components of SCADA have the likelihood of being overburdened with tasks compelling information to be released wholly, and this relates to attack. Stuxnet worm is a malware that attacks the SCADA model in the US; it was specifically programmed for SCADA in the industrial system. Stuxnet is now engineered so that its spread is minimized so that the likelihood of it being discovered is reduced and reduces unwanted attention. SCADA worm has increased indirect costs associated with the critical infrastructure, and this results in losses. A cyber-attack from Stuxnet can lead to economic loss and loss of lives; power blackouts in the US cities resulting from a power plant experiencing a cyber-attack have caused many to lose lives and some businesses to experience losses. Due to the increasing threats to the critical inf
