Part 3 of this tutorial overview of cybersecurity focuses on the U. Department of Defense DoD and its closer alignment with cybersecurity initiatives and standards in other parts of the Government. Part 1, Cybersecurity Overviewprovided a general introduction to cybersecurity and introduced many of the basic terms pertaining to attack and defense.
Part 2, Cybersecurity and the U. Highlighting some of these changes:. The single-word subject of DoDI These are discussed in Part 2. As noted, the subject of DODI It is a cnnssi and renaming of DoDI There are two levels of SGR, core more conceptual and technology.
STIGs cnszi applicable DoD policies and security requirements for specific technical products, as well as best practices vnssi configuration guidelines. It is presented in depth in Part 2. Overlays address additional factors beyond impact or diverge from the assumptions used to create the security control baselines.
Once the security categorization of the IS is complete, the general steps to security control selection are selecting the initial security control set and then tailoring its elements. Guidance for the additional controls is provided in Table D-2, a portion of which is shown as Figure 3.
Note that overlays are baseline-independent, meaning that they can be applied to any NSS baseline e. Tailoring modifies and aligns the initial control set to more closely account for conditions affecting the specific system i. As discussed in Part 2, FedRAMP is a Government-wide program that provides a standardized approach to security assessment, authorization, and continuous monitoring for cloud products and services.
Levels handle increasingly controlled unclassified information.
Security Controls Matrix (Microsoft Excel Spreadsheet)
Fnssi 1 is for unclassified, public information, level 2 is for unclassified information with limited access, and impact levels deal with controlled unclassified information, CUI, of increasing confidentiality.
Level 6 is for classified information. Security controls for all six levels do rely upon FedRAMP as their basis, but each level adds further controls and enhancements.
Part 3 of our three-part cybersecurity tutorial Part 1Part 2 has focused on cybersecurity and the U. Department of 1523 and all NSS. Importantly, we note the acceptance of NIST standards as the baseline of NSS security policy and controls, upon which additional controls and policies are placed for the special requirements of NSS.
Part 3: Cybersecurity and the U.S. Department of Defense
If you want to watch the video version of Part 3, look for it at the bottom of the cybersecurity landing page. The author of this three-part tutorial, Darrell Tanno, often engages in proposal support work and other marketing activities on a contract basis. For example, under the HIGH potential impact: A severe or catastrophic adverse effect means that, for example, the loss of confidentiality, integrity, or availability might: Highlighting some of these changes: Incorporated by reference in DoDI Key References in DoD Cybersecurity: Some of the policies outlined in DoDI For example, References include: Of note in Enclosure 1, References, is the inclusion of: As outlined in CNSSIpreserving the three discrete components, rather than using the HWM, provides granularity in allocating security controls to baselines and reduces the need for subsequent tailoring.
This is discussed further below and will be more apparent in Figure 2. Determining the impact values for all information types interacting with the IS and for the IS itself. Identifying overlays that apply to the IS and its operating environment to account for additional factors beyond impact that influence the selection of security controls.
All of the above is to be documented in the security plan. Guidance on Information System Security Control Selection, RMF Step 2 Once the security categorization of the IS is complete, the general steps to security control selection are selecting the initial security control set and then tailoring its elements.
Apply any overlay s identified as applicable cnswi security categorization, RMF Step 1. Document the above in the security plan.
Tailoring the Initial Security Control Set Tailoring modifies and aligns the initial control set to more closely account for conditions affecting the specific system i. Determine whether or not additional assurance—related controls are needed to increase the level of trustworthiness in cnsdi information system.
If so, tailor the set of controls accordingly. Summary of Part 3 Part 3 of our three-part cybersecurity tutorial Part 1Part 2 has focused on cybersecurity and the U.
