>Control Description

Maintain the currency, completeness, accuracy, and availability of the baseline configuration of the system using organization-defined automated mechanisms.

>DoD Impact Level Requirements

No specific parameter values or requirements for this impact level.

>Discussion

Automated mechanisms that help organizations maintain consistent baseline configurations for systems include configuration management tools, hardware, software, firmware inventory tools, and network management tools. Automated tools can be used at the organization level, mission and business process level, or system level on workstations, servers, notebook computers, network components, or mobile devices. Tools can be used to track version numbers on operating systems, applications, types of software installed, and current patch levels.

Automation support for accuracy and currency can be satisfied by the implementation of CM-8(2) for organizations that combine system component inventory and baseline configuration activities.
