Identification and Authentication decides whether your system knows who, and what, is connecting. Its 8 active requirements break into 44 determination statements in SP 800-171A, and 8 of those are organization-defined parameters for things like re-authentication, identifier reuse, password rules, and authenticator refresh. Four Revision 2 requirements are now withdrawn, and Authenticator Management (03.05.12) is new in Revision 3.
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.
