Highlighting some of these changes: All of the above is to be documented in the security plan.

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.

As noted, the subject of DODI A severe or catastrophic adverse effect means that, for cnwsi, the loss of confidentiality, integrity, or availability might: There are two levels of SGR, core more conceptual and technology.

Document the above in the security plan. These are discussed in Part 2.

This cssi identifies security control specifications needed to safeguard classified information stored, processed, or transmitted by national security systems NSS. Administrative change to reflect Appendix F vice K. Of note in Enclosure 1, References, is the inclusion of: Part 2, Cybersecurity and the U.

Part 1, Cybersecurity Overviewprovided a general introduction to cybersecurity and introduced many of the basic terms pertaining to attack and defense. Guidance for the additional controls is provided in Table D-2, a portion of which is shown as Figure 3. This document is designated FOUO. This document is comprised of four Privacy Overlays that identify security and privacy control specifications required to protect personally identifiable information PIIincluding protected health information PHIin National Security Systems NSS and reduce privacy risks to individuals throughout the information lifecycle.

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. If so, tailor the set of controls accordingly.


STIGs document applicable DoD policies and security requirements for specific technical products, as well as best practices and configuration guidelines. Department of Defense DoD and its closer alignment with cybersecurity initiatives and standards in other parts of the Government.

Overlays address additional factors beyond impact or diverge from the assumptions used to create the security control baselines.

Administrative changes from Rev 3 to Rev 4. For example, References include: Level 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. Security controls for all six levels do rely upon FedRAMP as their basis, but each level adds further controls and enhancements.

The instructions presented under this topic provide guidance and establishes technical criteria for specific national security systems issues.

Prescribes the handling and control of CCI. Incorporated by reference in DoDI The single-word subject of DoDI These instructions include technical or implementation guidelines, restrictions, doctrines, and procedures applicable to cybersecurity. Key References in DoD Cybersecurity: Summary of Part 3 Part 3 of our three-part cybersecurity tutorial Part 1Part 2 has focused on cybersecurity and the 2153.

This document is classified and can only be gotten by request to the CNSS Secretariat, please see attached document. 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.

All instructions are binding upon all U.

This is discussed further below and will be more apparent in Figure 2. Department of Defense and all NSS. For example, under the HIGH potential impact: 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 cjssi NSS. The author of this three-part tutorial, Darrell Tanno, often engages in proposal support work and other marketing activities on a contract basis.


It is a reissuance and renaming of DoDI Tailoring modifies and aligns the initial control set to more closely account for conditions affecting the specific system i. Administrative change from Appendix K to F. 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.

If you want to watch the video version of Part 3, look for it at the bottom of the cybersecurity landing page.

Note that overlays are baseline-independent, meaning that they can be applied to any NSS baseline e. Part 3 of this tutorial overview of cybersecurity focuses on the U. Determining the impact values for all information types interacting with the IS and for the IS itself. Apply any overlay s identified as applicable during security categorization, RMF Step 1. Levels handle increasingly controlled unclassified information. Government departments and agencies. Determine whether or not additional assurance—related controls are needed to increase the level of trustworthiness in the information cnzsi.

NSTISSI has not been re-released, the date showing dnssi records when an addition has been made to the description for this document.

Some of the policies outlined in DoDI It is presented in depth in Part 2. 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.
