Cybersecurity is the body of technologies, processes, and practices designed to protect networks, computers, programs, and data from attack, damage, or unauthorized access.

The term cybersecurity refers to techniques and practices designed to protect digital data — the data that is stored, transmitted, or used on an information system. After all, that is what a criminal wants: data. The network, servers, and computers are just mechanisms to get to the data. Effective cybersecurity reduces the risk of cyber-attacks and protects organizations and individuals from the unauthorized exploitation of systems, networks, and technologies.

Robust cybersecurity implementation is roughly based around three key terms: people, processes, and technology. This three-pronged approach helps organizations defend themselves from both highly organized attacks and common internal threats, such as accidental breaches and human error.

The attacks evolve every day. As attackers become more inventive, it is critical to properly define cybersecurity and understand cybersecurity fundamentals.
