FISMA, FedRAMP, and NIST: Federal Compliance Demystified

FISMA, FedRAMP, and NIST: Federal Compliance Demystified

FISMA, FedRAMP, NIST, DFARS, CJIS, HIPAA … Government compliance standards can seem like a veritable alphabet soup. Making matters even worse, a lot of them overlap, and many organizations aren’t certain which standards they need to comply with.

Even if your organization does not currently operate in the public sector, it is important to understand the fundamentals of FISMA, FedRAMP, and NIST. First, the U.S. government is the single largest buyer of goods and services in the world, and your company may ultimately want to tap this lucrative market. Second, any information security standards that the federal government implements will ultimately trickle down into state and local laws, as well as industry frameworks.

What is NIST?

The National Institute of Standards and Technology (NIST) is a non-regulatory agency that is part of the United States Department of Commerce. Its mission is “To promote U.S. innovation and industrial competitiveness by advancing measurement science, standards, and technology in ways that enhance economic security and improve our quality of life.”

Among many other responsibilities, NIST creates and promotes information security standards for the federal government. These standards are outlined in NIST’s SP-800 series of publications, including NIST SP 800-53 (also known as NIST 800-53), which outlines security controls for federal information systems and organizations and documents security controls for all federal information systems, except those designed for national security. Federal agencies must comply with NIST guidelines and standards within one year of their publication.

The controls outlined in NIST 800-53 are the basis for FISMA as well as FedRAMP, DFARS, CJIS, HIPAA, FedRAMP +, FedRAMP DoD IL 2, 4, 5, 6, and other standards.

What is FISMA?

FISMA was first enacted in 2002 as the Federal Information Security Management Act, then updated in 2014 to the Federal Information Security Modernization Act. FISMA applies to:

• All federal government agencies
• State agencies that administer federal programs, such as Medicare/Medicaid and student loans
• All private-sector firms that support federal programs, sell services to the federal government, or receive federal grant money

In a nutshell, FISMA requires the implementation of information security controls that utilize a risk-based approach. The primary framework for FISMA compliance is NIST 800-53. Organizations that demonstrate FISMA compliance are awarded an Authority to Operate (ATO) from the federal agency they are doing business with. This ATO applies only to that particular agency; if an organization has contracts with multiple federal agencies, they must obtain an ATO from each one. The logic behind this is that because every federal agency has different data security needs and vulnerabilities, different controls may apply. A FISMA assessment may be performed directly by the agency granting the ATO or a third-party security assessor.

What is FedRAMP?

The Federal Risk and Authorization Management Program (FedRAMP) was designed to support the federal government’s “cloud-first” initiative by making it easier for federal agencies to contract with cloud providers. Like FISMA, the controls outlined in FedRAMP are based on NIST-800-53.

Unlike FISMA, which requires organizations to seek an ATO from each individual federal agency, a FedRAMP ATO qualifies a cloud service provider to do business with any federal agency. Because FedRAMP ATO’s are more far-reaching, the certification process is far more rigorous. It must also be performed by a certified third-party assessment organization (3PAO) such as Lazarus Alliance. Finally, FedRAMP is more specific than FISMA. FISMA applies to information systems security in general, while FedRAMP applies only to cloud service providers and federal agencies that plan to use cloud service providers.

Since the FedRAMP certification process is so demanding, a FedRAMP ATO is beneficial even for cloud service providers that do not currently work with the federal government. Private-sector companies are aware of how difficult it is to comply with FedRAMP and recognize it as a gold standard of cloud security.

However, this is not to say the FISMA compliance process is “easy.” Organizations need to map the specific NIST 800-53 controls to the FISMA requirements of each agency they wish to do business with. There are hundreds of different controls, and figuring out which ones apply in each situation can be quite complex.

Complying with FedRAMP, FISMA, and NIST 800-53

Regardless of which compliance framework is right for your organization, it’s best to partner with a certified 3PAO so that you can get a clear picture of certification costs, timelines, and internal resource demands to facilitate an informed decision about pursuing FedRAMP or FISMA certification based on NIST 800-53.
