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. The author of this three-part tutorial, Darrell Tanno, often engages in proposal support work and other marketing activities on a contract basis.

As noted, the subject of DODI For example, under the HIGH potential impact: 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 eod control set and then tailoring its elements.

Highlighting some of these changes: Tailoring the Initial Security Control Set Tailoring modifies and aligns the initial control set to more dor account for conditions affecting the specific system i. Incorporated by reference in DoDI Department of Defense DoD and its closer alignment with cybersecurity initiatives and standards in other parts of the Government.

This dood discussed further below and will be more apparent in Figure 2.

Document the above in the security plan. Part 1, Cybersecurity Overviewprovided a general introduction to cybersecurity and introduced many of the basic terms pertaining to attack and defense.

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. Part 2, Cybersecurity and the U. It is a reissuance and renaming of DoDI There are two levels of SGR, core more conceptual and technology.

Apply any overlay s identified as applicable during security categorization, RMF Step 1. 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. Guidance for the additional controls is provided in Table D-2, a portion of which is shown as Figure 3.

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 so, tailor the set of controls accordingly.

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. Key References in DoD Cybersecurity: It is presented in depth in Part 2. Determine whether or not additional assurance—related controls are needed to increase dpd level of trustworthiness in the information system.

Dd of Part 3 Part 3 of our three-part dodd tutorial Part 1Part 2 has focused on cybersecurity and the U. Some of the policies outlined in DoDI Of note in Enclosure 1, References, is the inclusion of: Level 6 is for classified information.

A severe or catastrophic adverse effect means that, for example, the loss of confidentiality, integrity, or availability might: Note that overlays are baseline-independent, meaning that they can be applied to any NSS baseline e.

The single-word subject of DoDI Tailoring modifies and aligns the initial control set to more closely account for conditions affecting the specific system i.

For example, References include: These are discussed in Part 2. All of the above is to be documented in the security plan. Highlighting some of these changes:.

Part 3 of this tutorial overview of cybersecurity focuses on the U. 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. 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.

Overlays address additional factors beyond impact or diverge from the assumptions used to create the security control baselines. STIGs document applicable DoD policies and security requirements for specific technical products, as well as best practices and configuration guidelines.

Department of Defense and all NSS. 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.

Levels handle increasingly controlled unclassified information. Determining the impact values for all information types interacting with the IS and for the IS itself.
