Review Questions

• How does critical infrastructure impact the overall security of a nation?
  • Critical infrastructure is fundamental to a nation's security because it encompasses essential services that support daily life and economic activity. When these systems are compromised or disrupted, it can lead to chaos, loss of life, and significant economic damage. Protecting critical infrastructure ensures not only the safety of citizens but also the stability and resilience of the entire nation during times of crisis.
• Discuss the relationship between critical infrastructure and vulnerability assessments in enhancing security measures.
  • Vulnerability assessments play a key role in enhancing the security of critical infrastructure by identifying potential weaknesses that could be targeted during an attack or crisis. By systematically evaluating these vulnerabilities, stakeholders can implement targeted protective measures and improve response strategies. This proactive approach ensures that critical systems remain operational even in adverse situations, ultimately safeguarding public welfare and national interests.
• Evaluate the implications of cyber threats on the integrity of critical infrastructure systems and suggest strategies for mitigation.
  • Cyber threats pose significant risks to the integrity of critical infrastructure systems as they can disrupt operations, steal sensitive information, or even cause physical damage. To mitigate these risks, organizations must adopt comprehensive cybersecurity strategies that include regular risk assessments, employee training, implementing advanced security technologies, and fostering collaboration between public and private sectors. Strengthening these defenses will help maintain the resilience of critical infrastructure against increasingly sophisticated cyber attacks.
