Microsoft Purview: IRM RBAC Change (related to Data Security Investigations) Preview

Microsoft Purview Insider Risk Management (IRM) will introduce a new role, Data Security Investigation Contributor, allowing IRM Investigators to launch Data Security Investigations (DSI) from IRM cases. DSI, an AI-powered solution, helps identify, analyze, and mitigate data security risks. The public preview begins in April 2025, with general availability in June 2025. No admin action is required before the rollout. Microsoft Purview Insider Risk Management (IRM) will be adding a new role–Data Security Investigation Contributor–to the Insider Risk Management Investigators role group. This will allow members of the Insider Risk Management Investigators role group to launch a Data Security Investigation (DSI) from an IRM case. DSI is a new AI-powered solution that enables data security teams to identify incident-related data, conduct deep content analysis, and mitigate risk within one unified solution. DSI enables data security admins to efficiently identify incident-relevant content by searching their Microsoft 365 data estate to locate emails, Teams messages, Copilot prompts and responses, and documents. Once the investigation is scoped, DSI’s generative AI capabilities allow admins to gain deeper insights into the impacted data, revealing critical security risks and sensitive information. Investigative capabilities include the ability to categorize evidence, perform vector searches, and examine impacted data for security and sensitive data risks. DSI visualizes correlations between investigation data, users, and their activities. To mitigate identified risks, DSI facilitates secure collaboration between partner teams. Post-investigation learnings can be used to refine existing policies to strengthen an organization’s security practices. The integration between IRM and DSI allows an IRM investigator to identify when a risky user needs deeper investigation to launch a pre-scoped investigation directly from the user activity pane, allowing them to view content analysis related to that user and better assess post-incident data impact.
