Microsoft Graph offers a robust data repository that can enhance decision-making during threat detection and response, and its integration with Tines allows for advanced security automation. The process involves registering a new application in the Microsoft Azure App Registrations Portal to obtain an app ID and secret, selecting appropriate permissions or scopes, and creating a Tines credential using these details. Security analysts can automate tasks by utilizing Tines' HTTP Request Action, which accesses Microsoft Graph data, such as Outlook emails, through a GET request. This automation streamlines security operations, enabling analysts to focus on more impactful activities while maintaining thorough threat detection and response capabilities.
