Prompting in Security Copilot
Once you’ve set up Security Copilot, you can use prompts to input information. These prompts allow Security Copilot to generate answers that help you with your security-related tasks.
Prompts: These are the main input for the Security Copilot to generate answers. You can use promptbooks, prompt suggestions, or your own words to ask questions.
Process log: This shows the steps and sources that Security Copilot uses to form the response. You can cancel, edit, or delete your prompt at any time.
Feedback: You can provide feedback about the response by selecting Confirm, Off-Target, or Report. This can help improve Security Copilot.

Triage Incidents using Security Copilot
As a security operations center (SOC) analyst, you can use Security Copilot to quickly triage incidents based on alerts, entities, and threat intelligence. It uses natural language to query and summarize data from Microsoft 365 Defender and Microsoft Sentinel.
Use case example: A step-by-step demonstration of how Security Copilot can help an analyst investigate a possible credential theft incident assigned to them by Defender. The analyst uses Security Copilot to get more information about the user, device, and IP address involved in the incident, and to correlate it with a Microsoft Sentinel incident related to SAP data exfiltration.
Summary report: A concise report that the analyst can use to escalate the incident to the response team. The report includes the assessment of the original Defender incident, the link to the Sentinel incident, and the indicators of compromise. The report also highlights the threat actor and the C2 tool used by them.

Investigate an Incident in Security Copilot
As a security analyst investigating an incident, you can use Security Copilot to perform a comprehensive incident investigation using natural language and plugins. It is integrated into Microsoft 365 Defender and can also be used as a standalone experience.
Script analysis: Security Copilot can explain what a suspicious script is doing and provide an overall summary. It currently supports PowerShell, batch, and bash scripts.
Infrastructure analysis: Security Copilot can gather information about the reputation of indicators in a script, such as IP addresses or URLs, and flag them as malicious or benign.
Report generation: Microsoft Security Copilot can provide an assessment of the incident with supporting evidence and recommendations. It can also export the response and share the session with other analysts.

Manage Plugins in Security Copilot
To enhance the capabilities of Security Copilot, Microsoft has included a set of pre-installed plugins that are designed to work with Microsoft security services and other commonly used services and websites. Additionally, users have the option to add their own custom plugins, including those from OpenAI. Security Copilot can use plugins to access other services and websites that provide security information or actions.
Microsoft plugins: Security Copilot can use Microsoft plugins and connectors to access other Microsoft services that the organization already has access to, such as Microsoft Sentinel, Microsoft 365 Defender, Microsoft Entra, Microsoft Intune, Microsoft Defender Threat Intelligence, Logic Apps, and Natural Language to Microsoft 365 Defender KQL. These plugins are preinstalled and can be turned on or off by the user.
Other plugins: Security Copilot can also use other plugins that are not from Microsoft, such as ServiceNow, OpenAI, VirusTotal, and Shodan. These plugins need to be added by the user and may require additional setup steps.
Plugin management: Security Copilot allows the user to manage the plugins by turning them on or off, resetting and personalizing the settings, editing or deleting the plugin files, and adding new custom plugins. The user can also see which plugins are available and how to use them.
