Cybersecurity focuses on protecting data, devices, and networks from unauthorized access or attacks. It's built on three core principles known as the "CIA triad": Confidentiality (keeping information private), Integrity (ensuring information isn't tampered with), and Availability (making sure information is accessible when needed).
