To control access to all fields on a table, which ACL should be used?

The best choice for controlling access to all fields on a table is represented by using "table.". In ServiceNow, Access Control Lists (ACLs) play a crucial role in managing permissions for various components, including tables and fields. When specifying "table.", the asterisk (*) serves as a wildcard that indicates all fields within the specified table are included in the ACL.

This means that by applying the ACL at the table level with a wildcard, the access rules defined will automatically be applied to every field within that table, ensuring a consistent level of access control across all of its fields. It provides a streamlined approach, allowing developers to enforce security settings for an entire table without needing to create separate ACL rules for each individual field.

In this context, the other options do not effectively govern access to all fields across the entire table. For instance, "table.**" does not align with the correct syntax used in ServiceNow for wildcards, while "table.All" and "table.None" reflect specific conditions that do not encompass all fields within the table. Thus, "table.*" stands out as the most appropriate choice to manage access comprehensively.
