What Practice Area is concerned with limiting access to controlled baseline product files?

The practice area that is concerned with limiting access to controlled baseline product files is configuration management. Configuration management focuses on establishing and maintaining the integrity of products, systems, and their components throughout their lifecycle. This includes controlling and managing the baselines, which are formally approved versions of a product or its components.

Limiting access to controlled baseline product files is critical for maintaining their integrity and preventing unauthorized changes, which is a key aspect of configuration management. It ensures that only authorized individuals have access to specific files, thus protecting the integrity of the product and its development processes. This practice not only safeguards the physical artifacts but also helps in maintaining accurate records of changes made to the baseline, ensuring traceability and accountability.

The other practice areas do not specifically focus on the aspect of controlling access to these critical files in the same way as configuration management does. Access management deals more broadly with permissions and user authentication, data protection focuses on securing data from loss or unauthorized access, and change management addresses the processes of making and controlling changes but doesn't specifically limit access to the baseline files.
