True or False: An ACL is overruled by higher-level rules within the same structure.

The statement is true because in ServiceNow, Access Control Lists (ACLs) follow a hierarchy where higher-level rules can override more specific lower-level rules within the same structure. This means that if there are conflicting permissions defined at different levels for a particular resource, the higher-level rules will take precedence over lower-level ones. This hierarchy ensures that the most restrictive rules apply, allowing for more granular control over access permissions while maintaining a clear set of guidelines for prioritizing which rules govern application functionality.

In this context, if an ACL is defined at a broader level and a more specific ACL contradicts it, the broader one will prevail, leading to a consistent and predictable behavior in access control within the ServiceNow platform. Understanding this hierarchy is crucial for developers when configuring security settings to ensure that they achieve the desired access control without inadvertently leaving gaps or introducing conflicts.
