According to the VMware Carbon Black Cloud Endpoint Standard Skills Reference Materials, alerts are categorized as either “Threat” or “Observed” based on the severity and confidence of the event. “Threat” alerts indicate a high-severity and high-confidence event that is more likely to be malicious, such as a ransomware attack, a credential theft, or a network beacon. “Observed” alerts indicate a low-severity and low-confidence event that is less likely to be malicious, such as a suspicious registry modification, a fileless script execution, or a process injection. The categorization of alerts helps analysts prioritize their investigations and responses. References: VMware Carbon Black Cloud Endpoint Standard Skills Reference Materials, page 14, section 2.3.1.
