Cybersecurity
Cybersecurity is the practice and discipline concerned with protecting digital systems, networks, software, and data from unauthorized access, malicious attack, theft, disruption, and damage.
Overview
Its core principles — confidentiality, integrity, and availability, collectively known as the CIA triad — operate across scales from individual devices to critical national infrastructure. The field draws on cryptography and number theory for encryption, computer architecture for secure design, and behavioral science for understanding the human factors that remain the most critical vulnerability in most systems.
Why it matters
As virtually every sector of modern society depends on interconnected digital infrastructure, cybersecurity failures carry profound real-world consequences: breaches have disrupted hospitals, paralyzed energy grids, compromised elections, and exposed the personal data of billions. The economic cost of cybercrime is estimated in the trillions of dollars annually, making cybersecurity a major driver of both national security policy and international law.
