AnAccess Control rule (ACL)in ServiceNow defineswho can access dataandwhat actions they can performon that data. Each ACL consists of three primary components:
Object being secured– The specific table, field, or record that the rule applies to.
Operation– The type of action that is being secured (e.g., Read, Write, Create, Delete).
Permissions required– The conditions, roles, or scripts that determine whether access is granted.
ACLs evaluatewhether a user has permissionto access a specific table, field, or action.
Thesecurity rules are processed from most specific to least specific(e.g., field-level > table-level).
Permissions can be granted based onroles, conditions, or custom scriptsusing GlideSystem (gs).
