Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks. These cyberattacks are typically aimed at accessing, changing, or destroying sensitive information, extorting money from users, or interrupting normal business processes. Effective cybersecurity measures involve a combination of technology, processes, and practices designed to safeguard computers, networks, programs, and data from unauthorized access or damage. Key components of cybersecurity include network security, information security, endpoint security, application security, and cloud security. Additionally, cybersecurity involves continuous monitoring and improving defense mechanisms to counteract evolving threats.
