Configuration Management is where a system's security either holds steady or slowly drifts. Its 10 active requirements break into 61 determination statements in SP 800-171A, and 12 of those are organization-defined parameters, from review frequencies to the functions, ports, and services you restrict. Revision 3 adds requirements for component inventory, information location, and systems taken into high-risk areas, and 2 Revision 2 requirements are now withdrawn.
This course takes every requirement through the same three steps. First you learn what it asks for and the risk behind it. Then you see a practical way to put it in place that fits your environment. Last, you learn how it gets assessed and what evidence proves it. A running case, Harbor Point Machining (a fictional company), shows each step on a system that looks like yours.
