In ServiceNow,Access Control Rules (ACLs)determine user permissions for accessing tables, records, and fields. The evaluation order follows a structured hierarchy to ensure security and proper access control enforcement.
Table-Level Access Control– The system first checks if the user has access to the table. If the user does not have access at the table level, field-level ACLs are not evaluated.
Field-Level Access Control– If table access is granted, the system evaluates field-level access. A user must pass both the table-level and field-level conditions to access specific fields.
Row-Level Access– If there are row-level ACLs (e.g., access based on record ownership), they are also evaluated.
A. Ensures user has access to the fields in a table, before considering their access to the table– Incorrect because table access is evaluated first, not field access.
B. Ensures user can get to work as quickly as possible– Access controls prioritize security over speed, so this is not the primary result of ACL order evaluation.
C. Ensures user has access to the application, before evaluating access to a module within the application– Application access is controlled separately from ACLs and does not follow the same hierarchy.
