Solutions Reservoir™, an on-demand marketing support consultancy for high-tech industries, has released a three-part tutorial overview on cybersecurity. Part 1, Cybersecurity Overview, provides a general introduction to cybersecurity, and introduces many of the basic terms pertaining to attack and defense. It was developed to make those with minimal experience with the topic feel comfortable with many of its often-used terms and concepts. Because of the prominent role of the U.S. Government in cybersecurity and its formalization, Part 2, Cybersecurity and the U.S. Government, deals with topics frequently encountered in this environment (e.g. FISMA, FIPS, TIC 2.0 and MTIPS). Part 3, Cybersecurity and the U.S. Department of Defense, focuses on changes to DoD cybersecurity as it more closely aligns with other Government cybersecurity initiatives and standards including the new Risk Management Framework for DoD IT (RMF for DoD IT) and interaction between NIST SP 800-53 and CNSSI 1253.
