Cybersecurity threats refer to potential dangers that can compromise the integrity, confidentiality, and availability of information systems. These threats can come from various sources, including malicious software, phishing attacks, and unauthorized access attempts. Cybercriminals often target individuals, businesses, and government organizations to steal sensitive data or disrupt operations. Common types of cybersecurity threats include viruses, ransomware, and denial-of-service attacks. Viruses can corrupt files and spread to other systems, while ransomware locks users out of their data until a ransom is paid. Denial-of-service attacks overwhelm a system, making it unavailable to users, which can lead to significant financial losses.
