Alert Notification Rules

Correct Answer: B.

When an alert is triggered in Microsoft Defender for Endpoint, an Alert notification rule can be used to define how the alert should be handled. This includes options such as sending an email, creating a ticket, or triggering an automated action.

One of the filters that can be set as part of an Alert notification rule is Alert Severity. Alert Severity is a measure of the potential impact of an alert. Alerts are assigned a severity level based on the potential harm that they represent.

For example, a low-severity alert might indicate that a suspicious file has been detected on a single machine, while a high-severity alert might indicate that a critical system has been compromised.

By setting Alert Severity as a filter in an Alert notification rule, an organization can ensure that the right people are notified when important alerts are triggered. For example, a high-severity alert might trigger an immediate email to the security team, while a low-severity alert might simply be added to a log for future reference.

The other options listed in the question are also important filters that can be set as part of an Alert notification rule:

• Subject IDs: This filter allows alerts to be filtered based on the user or device that triggered them.
• Account: This filter allows alerts to be filtered based on the account that was targeted or affected.
• Alert IDs: This filter allows alerts to be filtered based on their unique identifier within the Microsoft Defender for Endpoint system.

In summary, while all of the options listed are important filters that can be set as part of an Alert notification rule, Alert Severity is the one specifically mentioned in the question.
