What is required from the Contractor regarding data access?

The requirement for the Contractor to control access strictly to assigned project staff reflects the need for maintaining data security and confidentiality. This approach ensures that sensitive information is only accessible to individuals who are directly involved with the project and have a legitimate reason to access that data. By limiting data access in this way, the Contractor can help protect against unauthorized use or disclosure of sensitive information, thus adhering to best practices in data management and compliance with relevant laws and regulations regarding data privacy.

The other options suggest broader access, which could pose risks to data integrity and confidentiality, undermining the project's objectives and potentially violating security protocols.
