DefinitionAn information security incident (情報セキュリティインシデント) is an event that threatens information security (an information security event, 情報セキュリティ事象) and has been assessed as likely to harm the business or the security of information.
ExplanationTypical examples include information leaks, malware infections, unauthorized access and service outages caused by failures. What is learned from the response goes into stronger measures so the same damage does not happen again.
AnalogyIt is like triage in an emergency room: each arriving patient is examined to judge how urgent the case is.
