Access control in computer operating systems is primarily concerned with managing permissions and rights for users and groups concerning system resources. Granting user rights to system objects ensures that individuals have appropriate access to files, applications, and other system resources necessary for their roles while protecting sensitive data from unauthorized access.

By implementing access control mechanisms, operating systems can enforce policies that help to maintain confidentiality, integrity, and availability of data. This process involves defining who can view or use information and under what circumstances, thereby mitigating risks related to data breaches or unauthorized actions within the system.

The other options do not align with the primary functions of access control. Storing historical data pertains more to data management and archiving rather than control. Reducing storage costs relates to optimizing resources rather than user access. Monitoring data synchronization also focuses on ensuring consistency between datasets, which is outside the realm of access control.
