Which ArcGIS Online capability ensures that content can be accessed by the right people?

The capability that ensures content can be accessed by the right people in ArcGIS Online is sharing. Sharing allows users to control who can view and interact with their content, such as maps, layers, and applications. This involves defining sharing settings, which can include options like sharing with everyone, sharing with the organization, or sharing with specific groups or individuals. By properly managing sharing settings, users can ensure that sensitive data is only accessible to authorized users while allowing broader access to public or collaborative content.

The other capabilities mentioned, such as apps, smart mapping, and analysis, do play important roles in the overall functionality of ArcGIS Online but do not specifically address the aspect of controlling access to content. Apps are tools created to visualize and interact with geographic data; smart mapping refers to techniques that enhance visualization based on data patterns, and analysis involves processing geographic information to derive insights. However, none of these functionalities directly manage or enforce access control to ensure that the right people can access specific content.
