Hardware Inventory - Most organizations lack a hardware inventory of what equipment they have, who has ownership or possession of it, and which departments or systems are using that equipment. This is a serious gap in their security program. In the event of a fire, equipment failure or theft, this lack of documentation may result in extended loss of operations and poor response.
It also makes proper configuration management impossible. A decision to roll out a patch or fix (or even a new service pack or release) will be limited by the ability to positively locate, update and test every affected device.
