True or False: Item-level security permissions override object-level security permissions.

Item-level security permissions are indeed a more granular level of security that can be implemented within systems, providing specific access controls at the item level as opposed to the broader object-level permissions. Typically, object-level permissions determine what a user can do with an entire object, such as view, edit, or delete, while item-level security refines these controls down to individual items or records within that object.

In the context of security hierarchies, item-level permissions can be deemed as an additional layer that complements object-level permissions rather than strictly overriding them. If a user has restricted permissions at the item level, they may not be able to access certain items even if they possess broader permissions at the object level. Therefore, the understanding that item-level permissions override object-level ones is not accurate, as both are meant to work together to establish an effective security model.

Hence, the statement that item-level security permissions override object-level security permissions is false.
