How often can the Escalation Level be set for alerts?

The option indicating that the Escalation Level for alerts can be set every 15 minutes is correct because this time frame allows for a balance between timely responses to potential security threats and not overwhelming the monitoring system or the personnel responsible for addressing those alerts. Regularly scheduled checks, such as every 15 minutes, enable organizations to stay proactive in dealing with security issues, ensuring that alerts are acknowledged and acted upon in a timely manner. This frequency can help minimize potential damage by quickly escalating incidents when necessary, maintaining the effectiveness of the email security posture.

Setting alerts too often, like every 5 minutes, can lead to alert fatigue, making it harder for personnel to prioritize genuine issues. Conversely, allowing longer intervals, such as 30 minutes or an hour, may increase the risk of delaying necessary actions against threats. Therefore, the 15-minute interval strikes an appropriate balance for effective monitoring and incident response.
