Cybersecurity involves protecting systems, networks, and data from digital attacks, unauthorized access, and other cyber threats. It encompasses a wide range of practices, including the use of firewalls, encryption, multi-factor authentication, and regular security updates. Cybersecurity also involves monitoring networks for suspicious activity, responding to incidents, and educating users on how to avoid common threats like phishing and malware. The goal of cybersecurity is to ensure the confidentiality, integrity, and availability of information in the face of evolving cyber risks.
