What is cybersecurity?

Cybersecurity refers specifically to the protection of systems, networks, and programs from digital attacks. This involves implementing various measures and practices to safeguard sensitive data and ensure the integrity, confidentiality, and availability of information systems. With the increasing number and sophistication of cyber threats, cybersecurity measures are critical for individuals and organizations to defend against unauthorized access, data breaches, and other cyber-related incidents.

The focus on protecting against digital threats makes this choice the only one that aligns accurately with the core principles of cybersecurity. It encompasses a wide range of practices, including network security, application security, information security, and end-user education.

In contrast, the other options describe unrelated concepts. Optimizing network speed pertains to enhancing the efficiency of data transmission, while the development of new hardware focuses on creating physical components for computers. The analysis of data for business decisions relates to the field of data analytics or business intelligence, which, while important, does not involve cybersecurity directly. Thus, the correct definition of cybersecurity is centered on protection against digital attacks, making it the most accurate choice.
