An up-to-date, complete, accurate, and readily available inventory of system components exists.
Employ automated discovery and management tools to maintain an up-to-date, complete, accurate, and readily available inventory of system components.
The system component inventory includes system-specific information required for component accountability and to provide support to identify, control, monitor, and verify configuration items in accordance with the authoritative source. The information necessary for effective accountability of system components includes the system name, hardware and software component owners, hardware inventory specifications, software license information, software version numbers, and—for networked components—the machine names and network addresses. Inventory specifications include the manufacturer, supplier information, component type, date of receipt, cost, model, serial number, and physical location. Organizations also use automated mechanisms to implement and maintain authoritative (i.e., up-to-date, complete, accurate, and available) baseline configurations for systems that include hardware and software inventory tools, configuration management tools, and network management tools. Tools can be used to track version numbers on operating systems, applications, types of software installed, and current patch levels.
