Cybersecurity is the practice of protecting computers, networks, and data from unauthorized access, attacks, and other cyber threats. It involves a combination of technologies, processes, and practices designed to secure sensitive information and prevent unauthorized access to computer systems.
Cybersecurity is important because it helps to protect individuals, businesses, and governments from the damaging effects of cyber attacks, such as the theft of sensitive data, the disruption of critical systems, and the loss of sensitive information.
By implementing strong cybersecurity measures, organizations can reduce the risk of cyber attacks and protect themselves from the damaging consequences of these attacks.
