Triage is a critical process in incident response that helps to assess the severity of an incident and allocate appropriate resources. In the context of Microsoft Sentinel, triage is the process of assigning a severity level to incidents to ensure they are prioritized and investigated in a timely manner. In this blog post, we will explore how to triage incidents in Microsoft Sentinel using the incident metrics feature.
Incident Metrics is a feature in Microsoft Sentinel that provides a centralized view of incident data for security operations teams. It enables security analysts to triage incidents based on their severity and investigate them accordingly.
With Incident Metrics, you can monitor the performance of your security operations center (SOC) by tracking the following metrics:
Incident volume: the number of incidents that have been generated.
Incident duration: the time taken to resolve incidents.
Incident backlog: the number of unresolved incidents.
Incident age: the age of unresolved incidents.
By using Incident Metrics, you can identify areas of improvement in your incident management process and optimize your SOC performance.
Triage is a crucial process in incident response. By assigning a severity level to incidents, you can ensure that they are handled in the appropriate manner. The following are the steps to triage incidents in Microsoft Sentinel:
Navigate to the Incidents tab in the Microsoft Sentinel portal.
Select the incident you want to triage.
In the incident details view, click the Severity drop-down list to select a severity level for the incident.
Select the severity level that best describes the incident. Severity levels can range from low to critical.
Click Save to apply the severity level to the incident.
Repeat steps 2-5 for all incidents that require triage.
Use Incident Metrics to monitor the severity levels of incidents and prioritize them accordingly.

In this blog post, we have explored how to triage incidents in Microsoft Sentinel using the incident metrics feature. We hope this information helps you improve your incident response capabilities and enhance your overall security posture.
Incident triage is a process of analyzing and prioritizing the alerts or incidents generated by security monitoring solutions in order to identify which ones need further investigation.
Incident triage is important in security operations because it allows security analysts to quickly identify and respond to high-priority security incidents, while avoiding wasting time and resources on false positives.

Incident metrics can be used to identify areas of the incident triage process that need improvement, such as reducing the time to triage or respond to incidents, and to monitor the effectiveness of incident response over time.
Incident metrics can be configured in Microsoft Sentinel by creating custom views and visualizations in the incident triage dashboard, and by using Microsoft Power BI to build custom reports and dashboards.
Automation and orchestration can help with incident triage in Microsoft Sentinel by enabling security teams to automate repetitive and time-consuming tasks, such as incident enrichment and analysis, and to orchestrate response workflows across different security solutions.
Integrating other security solutions with Microsoft Sentinel can provide additional context and visibility into security incidents, enabling security teams to make more informed decisions and respond more quickly and effectively to incidents.
