What could trigger an SEG alert?

An SEG alert is typically triggered by suspicious or abnormal activities that might indicate a security threat to an organization's email system. The correct choice identifies specific scenarios that are directly related to email security concerns. Anomalous email sending patterns, such as an unusual frequency of messages sent from a user account or communication from unauthorized sources, can indicate compromised accounts or spam campaigns. Additionally, the presence of malicious attachments or the detection of phishing attempts are critical triggers for alerts, as these can lead to data breaches or security incidents. By monitoring these activities, SEGs can help protect the integrity of an organization's communications and data, ensuring that threats are identified and addressed proactively.

Other answers do not pertain to security threats and don’t represent situations that warrant alerts. Increased customer satisfaction rates, regular automated backups of emails, and higher server maintenance costs are operational and administrative metrics, not indicators of potential security risks within the email environment.
