What is cybersecurity?

Cybersecurity is the practice of protecting computer systems, networks, programs, and data from digital attacks, unauthorized access, damage, or theft. It encompasses a wide range of technologies, processes, and practices designed to defend against cyber threats. Key domains include: network security (protecting the network infrastructure), application security (securing software from vulnerabilities), information security (protecting data integrity and confidentiality), operational security (procedures for handling sensitive data), disaster recovery, and end-user education. With increasing digitization, cybersecurity has become critical for businesses, governments, and individuals alike.
