Review Questions

• How do resilience enhancement strategies improve the effectiveness of cyber security measures?
  • Resilience enhancement strategies improve cyber security by implementing proactive measures such as redundancy, which ensures that systems remain operational even during an attack. Regular updates to software help patch vulnerabilities that could be exploited by attackers. Additionally, training employees about potential threats like phishing reinforces the human element of security, making organizations more robust against cyber incidents.
• Evaluate the role of technology in strengthening cyber security frameworks within organizations.
  • Technology plays a critical role in strengthening cyber security frameworks through the implementation of advanced tools like firewalls, intrusion detection systems, and encryption. These technologies help protect sensitive data from unauthorized access while monitoring network traffic for suspicious activity. Furthermore, leveraging AI and machine learning allows organizations to automate threat detection and response processes, significantly enhancing their overall cyber defense capabilities.
• Assess the implications of a successful cyber attack on critical infrastructure for national security and economic stability.
  • A successful cyber attack on critical infrastructure can have dire implications for national security and economic stability by disrupting essential services such as power supply, healthcare, and transportation. Such disruptions can lead to widespread panic, loss of trust in government capabilities, and significant economic repercussions due to halted operations. Moreover, it can expose vulnerabilities within national defense systems, prompting concerns about overall safety and preparedness against future threats.
