The TEEX/NERRTC Cybersecurity online courses are designed to ensure that the privacy, reliability, and integrity of the information systems that power our global economy remain intact and secure. These DHS/FEMA-certified courses are offered through three discipline-specific tracks targeting general, non-technical computer users, technical IT professionals, and business managers and professionals.
The following course tracks have been reviewed by the American Council on Education (ACE) for college credit.
The courses are broken into tracks for no-techs, techs, and managers. Not sure how in-depth each of them is but general if you have a class like Business Information Continuity it takes at least a couple hours to complete.
