MA-03 Maintenance Tools
Control: The organization approves, controls, and monitors the use of information system maintenance tools and maintains the tools on an ongoing basis.
Supplemental Guidance: The intent of this control is to address hardware and software brought into the information system specifically for diagnostic/repair actions (e.g., a hardware or software packet sniffer that is introduced for the purpose of a particular maintenance activity). Hardware and/or software components that may support information system maintenance, yet are a part of the system (e.g., the software implementing “ping,” “ls,” “ipconfig,” or the hardware and software implementing the monitoring port of an Ethernet switch) are not covered by this control.
(1) The organization inspects all maintenance tools carried into a facility by maintenance personnel for obvious improper modifications.
Enhancement Supplemental Guidance: Maintenance tools include, for example, diagnostic and test equipment used to conduct maintenance on the information system.
(2) The organization checks all media containing diagnostic and test programs for malicious code before the media are used in the information system.
(3) The organization checks all maintenance equipment with the capability of retaining information so that no organizational information is written on the equipment or the equipment is appropriately sanitized before release; if the equipment cannot be sanitized, the equipment remains within the facility or is destroyed, unless an appropriate organization official explicitly authorizes an exception.
(4) The organization employs automated mechanisms to restrict the use of maintenance tools to authorized personnel only.
