When categorizing a security incident for response, which category represents the highest priority?

• A. Minor
• B. Moderate
• C. Major
• D. Critical

Answer: (D)

In incident response, priority is driven by the severity and urgency of the impact. The highest-priority incidents are those that pose severe risk to people, critical systems, data, or operations, demanding immediate containment and rapid use of resources. This level is described as Critical because it signals that the situation could cause widespread disruption, significant data loss, safety concerns, or severe financial or regulatory consequences. Because of that, it triggers instant escalation, with on-call teams mobilized right away and top readiness across the organization. Lower levels—Major, Moderate, or Minor—indicate progressively less severe impact and thus require correspondingly less urgent action. So, the category representing the highest priority is Critical, since it encapsulates the most urgent need for rapid, aggressive response.
