A security incident refers to any event that compromises the confidentiality, integrity, or availability of information or systems. This can include unauthorized access to data, malware infections, or data breaches. Organizations often have protocols in place to detect and respond to these incidents to minimize damage and protect sensitive information. Common types of security incidents involve phishing attacks, where attackers trick individuals into revealing personal information, and ransomware attacks, which lock users out of their systems until a ransom is paid. Effective incident response plans are crucial for organizations to quickly address and recover from these threats.
