Which specific tooling is referenced for managing security policies in Pega?

The correct choice, Dev Studio, is the primary environment in Pega where developers can create and manage various application components, including security policies. In Dev Studio, developers have access to a range of tools that enable them to define and configure security settings for their applications. This includes managing access roles, privileges, and the authentication mechanisms required for user access, which are essential elements of security policy management.

Dev Studio provides a user-friendly interface for defining who can access specific parts of an application and what actions they can perform. It also allows for the implementation of security best practices through role-based access control, thereby helping to safeguard sensitive data and functionality from unauthorized access.

The other options do not specifically focus on security policy management. App Studio is more oriented towards application design and user experience, Data Warehouse pertains to data storage and analytics, while an Identity Management System is a broader concept for managing user identities across systems rather than a specific tool associated directly with Pega security management.
