What best describes the difference between an OT alarm and a cyber incident?

• A. An alarm is a notification of a potential issue; a cyber incident is a confirmed security event requiring containment and remediation.
• B. An alarm triggers containment actions.
• C. A cyber incident is only about physical safety.
• D. An alarm is a formal incident response.

Answer: (A)

The key idea is that alarms and cyber incidents serve different roles in OT security: alarms are alerts signaling a potential problem, while a cyber incident is a confirmed security event that requires actions to contain and remediate. An alarm comes from sensors or control systems and indicates something may be going wrong, but it does not by itself prove a breach and does not automatically trigger containment. A cyber incident, on the other hand, is a verified security event that impacts cyber assets and operations, demanding formal containment, eradication, and recovery steps. So the best description is that an alarm is a notification of a potential issue, whereas a cyber incident is a confirmed security event requiring containment and remediation. The other statements mischaracterize alarms as actions or misdefine incidents as solely physical safety events or as the formal response itself.
