How is layer sharing configured in ArcGIS?

Layer sharing in ArcGIS is configured through the sharing settings for each layer. This involves specifying who can view, edit, or use a layer based on roles, groups, or specific users. Layers in ArcGIS can be set to be publicly accessible, restricted to certain groups, or fully private, allowing administrators to control access in a granular way.

When managing layer sharing, administrators use the ArcGIS Portal interface or the ArcGIS Online settings to define these sharing permissions for each layer individually. This flexibility is crucial for collaborative GIS environments where data needs to be shared with different stakeholders while maintaining privacy and security for sensitive information.

Other methods, such as a centralized user management system, primarily facilitate user access and authentication but do not directly configure share settings for layers. Similarly, updating server configuration files and executing direct database queries pertain more to system administration and database management rather than the specific act of configuring sharing settings for layers.
