**Cybersecurity** is a set of **technologies, practices, and processes designed to protect digital systems, networks, software, and data from cyberattacks, unauthorized access, damage, or theft**. It encompasses several key areas, including: * **Network security**: Protecting network infrastructure from intrusions and attacks. * **Application security**: Ensuring software is free of vulnerabilities that could be exploited. * **Information security**: Safeguarding the confidentiality, integrity, and availability of data. * **Device security**: Securing user devices against malware and physical attacks. * **Incident response and recovery**: Detecting threats, responding to attacks, and restoring systems after an incident. Cybersecurity is essential for protecting individual privacy, business operations, and national security, especially in the era of rapid digital transformation and increasing reliance on technology.
