Critical infrastructure refers to the physical and cyber systems and assets that are vital to the nation’s security, economy, public health, and safety. These infrastructures include sectors such as energy, transportation, water, healthcare, and communications, which collectively sustain the daily functions of society. The significance of critical infrastructure to homeland security cannot be overstated, as disruptions or attacks on these systems can lead to catastrophic consequences, including economic downturns, loss of life, and compromised national security. Protecting these infrastructures involves comprehensive strategies encompassing prevention, preparedness, response, and recovery efforts tailored to each sector's unique vulnerabilities.

The energy sector, for example, encompasses electricity generation, transmission, and distribution systems that power homes, businesses, and government operations. Its security is paramount due to its central role in supporting all other critical sectors. A potential means of attack on the energy sector involves cyberattacks targeting the control systems of the electrical grid. Such cyberattacks could be orchestrated by malicious actors seeking to cause widespread power outages. Hackers may exploit vulnerabilities in Supervisory Control and Data Acquisition (SCADA) systems, which monitor and control power grid operations, by introducing malware or malware variants designed to disrupt operations. An example is the targeted use of ransomware or malware to disable grid controls, leading to blackouts that impair essential services, disrupt communications, and threaten public safety.

Protective measures include cybersecurity enhancements such as intrusion detection systems, network segmentation, and regular system audits. Agencies like the Department of Homeland Security have emphasized the importance of resilience planning, including backup power supplies, rapid response teams, and coordinated communication strategies to mitigate the impact of such attacks. Overall, safeguarding critical infrastructure sectors like energy requires a multi-layered approach integrating technological defenses, policy frameworks, and collaborative efforts among government, private sector, and community stakeholders.
