Cybersecurity

Cybersecurity involves protecting systems, networks, and data from cyber threats. This field encompasses a wide range of practices and technologies designed to safeguard information from unauthorized access, attacks, damage, or theft. Cybersecurity includes preventive measures such as firewalls, encryption, and secure coding practices, as well as detection and response strategies like intrusion detection systems and incident response plans. This topic covers the principles, best practices, and latest trends in cybersecurity, including emerging threats and the evolving landscape of cyber defense.
