If you’re a defense contractor and have a DFARS 7012 clause in your contract, then you are required to protect CUI and meet all 110 NIST 800-171 requirements. The only way to definitively meet controls is to have a System Security Plan (SSP) that spells out the policies and procedures your organization has adopted to do just that. This documentation cannot just make sense to you – it also has to make sense to a potential outside auditor.
This blog will provide a helpful guide for how to create a sufficiently robust SSP that can meet the scrutiny of auditors. Creating an SSP can be challenging and time consuming, but the process doesn’t need to be opaque.
A System Security Plan (SSP) has been required by NIST 800-171 since November 2016. NIST 800-171 control security requirement 3.12.4 states that organizations must “develop, document, and periodically update system security plans that describe system boundaries, system environments of operation, how security requirements are implemented, and the relationship with or connections to other systems.”
In essence, an SSP describes the cybersecurity program that a defense contractor has in place. The SSP needs to go through each NIST 800-171 control and explain how the control is implemented, monitored and enforced. This can be through policy, technology or a combination of both. The SSP will also outline the roles and responsibilities of security personnel to ensure that CUI is appropriately protected.
An SSP is key to more than just NIST 800-171. In order to achieve DFARS 7012, DFARS 7019, and soon-to-be CMMC compliance, you’ll need an SSP. DFARS 7012 requires NIST 800-171 compliance and DFARS 7019 requires contractors to submit their NIST 800-171 self assessment scores in the SPRS database. This score can only be accurately calculated and submitted if a contractor has a SSP in place.
Your SSP needs to go through the 110 controls of NIST 800-171 one by one and explain how you’ll satisfy each and every one of them. Each control can be satisfied by technology, policy or a combination of both.
If a control can be met by technology, the IT team can simply state that the control is met by a technology solution. If, however, the control is met by a training or an incident response plan, then explaining the process of how the organization meets those requirements becomes much more complex. Many contractors will turn to a certified consultant to assist in this process who is better able to provide an overview of the security controls used by the organization.
Control AC L1-3.22 provides a simple example of the necessary policies and procedures required. This control states:
Control information posted or processed on publicly accessible information systems.
The policy could state:
The SSP procedure might state:
Develop, document, and periodically update system security plans that describe system boundaries, system environments of operation, how security requirements are implemented, and the relationships with or connections to other systems.
The supporting policy might state:
The associated procedures documented within the SSP could then state:
-The date the SSP was updated
-Updates made to the SSP
-Administrator responsible for the updates
-Updated version number of the SSP
a. Complete a full Top-Secret Tier 5 background check that must be fully adjudicated (not Interim)
b. The Acting Authority assigns the resource with the Administrator role
i. The Acting Authority will assign the role of Administrator through the creation of a ticket in the internal company ticket system.
ii. That ticket will then be routed to the IT Manager
iii. The IT Manager will then update the Roles and Responsibilities matrix to ensure that the new Administrator’s information is correctly reflected
a. Document is sent via email or shared drive link to the authorized Document Reviewer listed on the Roles and Responsibility matrix.
b. The document reviewer will review the document and then submit it to the Acting Authority with any additional information required.
c. The Acting Authority will review the document and ask any questions or gain any additional clarification from the Administrator before ensuring that the document is signed and then disseminated to all stakeholders.
And this control is not unique in its complexity. Many of the NIST 800-171 controls require this level of detail in order to fulfill the requirements of building an accurate SSP and creating an SSP that could pass an audit.
As you see above, creating an SSP can be a time consuming process. That said, it isn’t optional. So what can you, an efficiency-minded small to medium sized business (SMB) do to reduce the burden?
1. Self-assess first.
The best way to get started in creating your organization’s SSP is to start with a self-assessment against the 110 NIST 800-171A requirements. This exercise will force you to review each control and take an inventory of what you have in terms of policy, technology. From there you can see the gaps of which controls you need to work on or which ones you already meet.
2. Use a template
After completing a self-assessment, you should download one of the many SSP templates available online and start writing the documentation for each control. Then you have the outline for your SSP.
The disadvantage of attempting to create an SSP in-house is that there are many nuances to writing up the processes and creating the robust documentation you will need. Indeed, trying to do it on their own is where many contractors fail. A typical SSP along with its supporting documentation ranges from 80-120 pages. Without the help of a trained consultant or expert, your SSP policies and procedures will likely not align because you are not implementing the processes you claimed to. As a result, your SSP won’t pass an audit.
PreVeil can reduce the need for expensive external consultants. We offer a CMMC compliance documentation package for organizations that have deployed our Email and File Sharing platform for protection of CUI.
PreVeil’s package provides you with a SSP template for the 102 out of 110 NIST 800-171 controls which PreVeil meets as well as policy templates for all 14 NIST families. PreVeil also provides a customer responsibility matrix (CRM) and Plan of Action and Milestones (POA&M) for the controls that PreVeil doesn’t meet.
While PreVeil’s template still requires contractors to customize the SSP template to how their environment works, the CRM saves contractors hundreds of hours of prep and consultant time. PreVeil’s template helps contractors know who is responsible for meeting the control whether it is their organization, PreVeil or AWS – for example. And the PreVeil SSP template provides a POA&M for the controls left unmet by our existing package.
PreVeil can also assist contractors in finding a compliance expert who understands the CMMC landscape and can help their business work through their compliance questions. With PreVeil, customers have a partner, not just a solution.
If you’re a defense contractor, you must create a SSP in order to continue working with the Department of Defense (DoD). If you don’t already have a robust SSP that can stand up to an audit, then you’re already in breach of compliance. Don’t waste more time.
