In a Microsoft 365 E5 subscription, what is the first step to enable remote shell connections from the Defender portal?

To enable remote shell connections from the Defender portal in a Microsoft 365 E5 subscription, configuring role-based access control (RBAC) is the essential first step. RBAC allows you to assign specific permissions to users or groups, ensuring they have the appropriate access required to perform actions within the Defender portal.

By properly setting up RBAC, you can designate roles that have the capability to execute remote shell commands. This access is necessary to maintain security and control over who can initiate and manage these connections, thus minimizing the risk of unauthorized access or actions within the environment.

Establishing device groups, modifying permissions for Microsoft 365 Defender, or enabling automated investigations are additional steps that may be involved in broader security management practices. However, unless the necessary permissions are established upfront through RBAC, users will not be able to perform remote shell connections, regardless of these subsequent configurations.
