Which factor is an essential consideration for ensuring data security?

Access controls and permissions are fundamental to ensuring data security because they determine who has the ability to view, manipulate, or manage data. By implementing strict access controls, organizations can restrict data access to authorized users only, thereby reducing the risk of unauthorized access, data breaches, and potential misuse of information. This means managing user roles, permissions, and ensuring that sensitive data is only accessible to individuals who need it for their specific functions.

In contrast, while availability of data is important for information systems to function effectively, it does not directly address security concerns. Physical storage of data is crucial for managing where data resides physically, but it does not account for who can access that data. Data consolidation, though it may improve efficiency in data management, does not inherently enhance security measures. Thus, prioritizing access controls and permissions is key to protecting sensitive data and maintaining the integrity of information systems.
