Summarize an incident with Microsoft Copilot in Microsoft Defender

Applies to:

  • Microsoft Defender XDR
  • Microsoft Defender unified security operations center (SOC) platform

Microsoft Defender XDR applies the capabilities of Copilot for Security to summarize incidents, delivering impactful information and insights to simplify investigation tasks. Attack investigation is a crucial step for incident response teams to successfully defend an organization against further damage from a cyber threat. Investigations can often be time-consuming as it involves numerous steps. Incident response teams need to understand how the attack happened: sort through numerous alerts, identify which assets and entities are involved, and assess the scope and impact of an attack.

Incident responders can easily gain the right context to investigate and remediate incidents through Defender XDR's correlation capabilities and Copilot for Security's AI-powered data processing and contextualization. With an incident summary, responders can quickly get important information to help in their investigation.

The incident summary capability is available in the Microsoft Defender portal through the Copilot for Security license. This capability is also available in the Copilot for Security standalone experience through the Microsoft Defender XDR plugin.

This guide outlines what to expect and how to access the summarizing capability of Copilot in Defender, including information on providing feedback.

Summarize an incident

Incidents containing up to 100 alerts can be summarized into one incident summary. An incident summary, depending on the availability of the data, includes the following:

  • The time and date when an attack started.
  • The entity or asset where the attack started.
  • A summary of timelines of how the attack unfolded.
  • The assets involved in the attack.
  • Indicators of compromise (IoCs).
  • Names of threat actors involved.

To summarize an incident, perform the following steps:

  1. Open an incident page. Copilot automatically creates an incident summary upon opening the page. You can stop the summary creation by selecting Cancel or restart creation by selecting Regenerate.

  2. The incident summary card loads on the Copilot pane. Review the generated summary on the card.

Selecting Open in Copilot for Security opens a new tab to the Copilot for Security standalone portal where you can input prompts and access other plugins.
