Is it possible for an entity or a division part of an organization to be certified ISO 27001, specifically the Division Information Security Management System?
Yes, that is possible. ISO27001 requires you to define the scope of the certification, so you could restrict the scope to that one specific division.
Of course, any smart auditor would check what relations that division has with other divisions and which risks and controls are related to that.
Required, but never shown
