National security refers to the protection of a nation’s interests, sovereignty, and well-being from internal and external threats. While it traditionally encompasses military defense, it increasingly involves safeguarding critical infrastructure, economic stability, and the safety of citizens. In the context of cybersecurity, national security is concerned with defending against cyberattacks that could disrupt essential services, compromise sensitive information, or undermine public trust. As cyber threats evolve in sophistication, securing digital systems, networks, and data has become a fundamental aspect of a nation’s overall security strategy.
