Complying with DoD Cybersecurity Requirements: What do NIST 800-171 Revision 2 and 800-171B Drafts Mean for Your Business?

By Eric Noonan • June 24, 2019

NIST 800-171 Revision 2 and 800-171B drafts were released for comment last week, and as expected there have been no major changes proposed to the controls in NIST 800-171 Revision 2. For DoD contractors waiting to implement the required security requirements of NIST 800-171 Revision 1 pending the latest updates, the proposed updates won’t buy you any time. The fact is enforcement is underway and compliance with DoD cybersecurity requirements is a go/no go decision if you are serious about being eligible to do business with the DoD.

The 800-171B draft enhanced security controls are in addition to 800-171 controls, in cases where the information held by the contractor is determined to be a high-value target. The enhanced requirements are to be applied to nonfederal systems and organizations processing, storing, or transmitting controlled unclassified information (CUI), when such information is contained in a critical program or designated high-value asset. The enhanced security requirements of the 800-171B draft were designed to address advanced persistent threats (APTs) and are mapped to the security controls in NIST 800-53. The implied maturity level required and associated costs with implementing the 800-171B draft enhanced security controls is significant.

The enhanced security requirements include three, mutually supportive and reinforcing components:

(1) penetration resistant architecture;

(2) damage limiting operations; and

(3) designing for cyber resiliency and survivability.

The Path Forward for DoD Contractors

With a tremendous amount of activity related to The Cybersecurity Maturity Model Certification (CMMC), DCMA audits of NIST 800-171 compliance, False Claims Act litigation, and the 800-171 revisions and supplements, the path forward for DoD contractors is clear:

Fund and execute compliance with NIST 800-171 now. Despite all of the proposed changes, the fact remains that the DFARS 252.204-7012 clause in ANY of your contracts requires the implementation of NIST 800-171. That is your contractual requirement and all changes proposed so far rely on NIST 800-171 as a foundation of compliance.

There has been a level of paralysis by analysis across industry caused by the questions of cost reimbursement, proposed changes and uneven auditing of compliance. This is the kind of noise that has caused many DoD contractors across the supply chain to delay their DFARS compliance efforts but that high-risk approach invites legal and competitive pain that should be avoided. While there are many changes to be aware of CyberSheath advises focusing on what you are required to do today as the best approach to current and future compliance requirements. Nothing that has been proposed eliminates the requirement to implement NIST 800-171.

Compliance with the DFARS and NIST 800-171 requirements involves much more than writing a System Security Plan (SSP) and vendors selling you a tool to get compliant are misleading you. There are 110 security requirements in NIST 800-171 and you have to actually implement them, there isn’t a single product to solve this problem.
