❓ Frequently Asked Questions
What is critical infrastructure in cybersecurity?
Critical infrastructure comprises essential systems and services—like power grids, water supply, transportation, and healthcare—that society relies on. Disruptions can affect safety, economy, and national security.
Why are critical infrastructure networks attractive targets for cyber threats?
Because they are vital to daily life, highly interconnected, often use legacy technologies, and a successful attack can disrupt essential services and public safety.
What is the goal of cybersecurity for critical infrastructure?
To protect the confidentiality, integrity, and availability of these systems, prevent unauthorized access and disruptions, and maintain continuous, safe operations.
What are common strategies to safeguard critical infrastructure?
Defense-in-depth, network segmentation, continuous monitoring, timely patching, incident response and recovery planning, and collaboration between public and private sectors.
