Access Control List (ServiceNow) (ACL)

Security rule granting create, read, write or delete access to tables and fields based on roles, conditions and scripts.

Definition

ACLs are evaluated table-then-field, from most specific to most general, and a user must pass both table and field ACLs. All three components (roles, condition, script) of an ACL must evaluate true. Security attribute based ACLs and deny-unless ACLs exist in newer releases.

Example

incident.* (read) for itil role; incident.short_description (write) condition: state != closed

Exam tip

Table.None controls row access; table.* controls default field access; table.field is most specific.
