Fedramp vs nist

Federal government contracts are vastly different from corporate ones. They have distinct control requirements and measures that need to be kept pace to safeguard sensitive data. 

Not obtaining certain certifications can be a non-starter for companies in the public sector looking to obtain government contracts. And with each one having its own set of rules, CISOs quickly find out just how challenging it can be to navigate this space. 

For the purpose of this article, we’re focusing on two such frameworks—NIST 800-53 and FedRAMP. Read on to learn about the key differences between FedRAMP and NIST 800-53 and how to pick between the two.

NIST 800-53 Overview

NIST (National Institute of Standards and Technology) Special Publication 800-53 recommends security and privacy controls for federal systems under FISMA rules. It was first published in 2005 and has been revised several times to adapt to evolving cybersecurity threats and technologies.

The creation of SP 800-53 involved a collaborative effort with contributions from various sectors, including defense, intelligence, civil government, cybersecurity experts, and organizations.

In simple terms, it’s a detailed guide to cybersecurity that covers topics such as who can access what, how to handle problems and system setup.

The guide is part of NIST’s 800 series, covering crucial information system security elements. Even though the framework was initially created with federal systems in mind, it has since been updated for non-federal systems.

Background on controls

NIST SP 800-53 consists of 20 different security control groups categorized into 20 families or areas of operation. Among controls, monitoring for unauthorized access, responses to incidents, and configuration management are some areas it covers.

These guidelines, part of the 800 series of NIST Special Publications, deal with computer security and cybersecurity. Initially used solely in federal information systems, the new versions also cover non-federal systems.

What is FedRAMP? 

FedRAMP (Federal Risk and Authorization Management Program) is a framework that defines the level of risk associated with cloud services used by U.S. federal agencies. In simple terms, FedRAMP enables you to use contemporary cloud technologies, prioritizing security and safeguarding federal information.

It focuses on three main areas: security processes that include but are not limited to authorization, security assessment, and monitoring.

The mission of FedRAMP is to shape a uniform and durable cloud security for the administration of the United States. This can help cloud products have security standards that meet specific requirements and free the market for cloud services for a mature environment. This encourages government agencies to use cloud services more widely and fosters collaboration by sharing insights and solutions across the government.

How is FedRAMP connected to NIST 800-53?

FedRAMP is connected to NIST 800-53 because as FedRAMP simplifies the security assessment process for Cloud Service Providers, CSPs need to follow the security controls and enhancements set out in NIST Special Publication 800-53. 

Moreover, the NIST CSF advises using threat intelligence to spot, stop, and handle cyber threats better. On the other hand, FedRAMP needs cloud service providers to offer ongoing monitoring reports to inform federal agencies about security concerns.

For example, a Software as a Service (SaaS) company operates from a single centralized data center or hosting facility. As a result, all users of this SaaS platform benefit from the same level of physical security measures in place at that facility. This uniformity greatly reduces the risk for all users. 

On the other hand, when different government agencies acquire this SaaS solution, each agency is tasked with setting up and maintaining its own secure password protocols. This decentralized approach ensures that each agency can tailor their password controls to meet its specific security needs effectively.

In other words, FedRAMP uses NIST 800-53 as its guideline so that cloud services meet federal security standards.

ScopeFedRAMP provides a steady way to check, approve, and monitor CSPs to ensure they meet top-notch security standards.
The NIST 800-53 standards aim to secure federal information systems. They offer a detailed framework for federal agencies and organizations handling federal information to establish and uphold strong security controls.
SuitabilityFedRAMP rules apply to all federal agencies using CSPs to handle federal information, from collection to disposal.US-based contractors and federal agencies are required to follow NIST 800-53. Even though it’s mandated for them, many state and private sectors adopt it as their security control framework.
Security controlsThe FedRAMP framework tells CSPs which security controls to use and how to show they’re using them. These controls match up with the NIST 800-53 guidelines.NIST controls help strengthen a company’s cybersecurity, risk management, and information protection.
Continuous monitoringContinuous monitoring is a key principle emphasized by NIST 800-53. It involves ongoing surveillance to detect security vulnerabilities, threats, and incidents.FedRAMP mandates that CSPs use continuous monitoring to maintain compliance with security standards over time.

Crucial requirements of NIST 800-53 & FEDRAMP

NIST 800-53 and FedRAMP have essential requirements to ensure robust cybersecurity. 

NIST 800-53

NIST SP 800-53 offers a set of controls to help build secure and resilient federal information systems. These controls cover operational, technical, and management standards that ensure information systems maintain confidentiality, integrity, and availability.

The controls are broken—low, moderate, and high, split into 18 families. The NIST SP 800-53 security control families are:

  • Access Control
  • Awareness and Training
  • Audit and Accountability
  • Contingency Planning
  • Configuration Management
  • Identification and Authentication
  • Incident Response
  • Maintenance
  • Media Protection
  • Personnel Security
  • Physical and Environmental Protection
  • Planning
  • Risk Assessment
  • Program Management
  • Security Assessment and Authorization
  • System and Communications Protection
  • System and Information Integrity
  • System and Services Acquisition


Here are the requirements of FedRAMP:

  • FedRAMP requires companies to have a federal agency sponsor to get through the authorization process. Without a Federal sponsor, a company cannot apply for FedRAMP.
  • FedRAMP categorizes Cloud Service Offering (CSO) into one of three security profile levels: low, moderate, and high, depending on the data your organization stores and processes. Your sponsor must determine which category would apply to you, given the nature of your services. Usually, companies are categorized as either high or medium-risk.
  • The number of controls to be implemented would be ~325 (for Medium risk) or ~500 (for High-risk vendors).
  • 3PAO stands for third-party assessment organization in FedRAMP. They check your cybersecurity and make a Readiness Assessment Report (RAR) for you.
