NIST 800-53 vs. NIST 800-171
NIST 800-53 and NIST 800-171 are two different sets of security controls developed by the National Institute of Standards and Technology (NIST) in the United States.
NIST 800-53 provides a comprehensive set of security and privacy controls for federal information systems and organizations, while NIST 800-171 provides a subset of these controls specifically for non-federal entities that handle controlled unclassified information (CUI) in their systems.
While NIST 800-53 covers a wider range of security controls, NIST 800-171 focuses on protecting CUI, which includes sensitive but unclassified information such as financial, medical, and technical data.
Both sets of controls are intended to help organizations protect their information systems and data from a variety of threats, including cyberattacks, unauthorized access, and data breaches. However, NIST 800-171 has more specific requirements related to CUI protection, such as incident reporting, media protection, and access controls.
How Does NIST 800-53 Relate to FISMA?
The Federal Information Security Modernization Act (FISMA) of 2014 requires federal agencies to develop, document, and implement a risk-based information security program to protect their systems and data against threats and vulnerabilities. NIST 800-53 is a critical component of FISMA compliance because it outlines the minimum security controls that federal agencies must follow to meet the standards set by FISMA.
FISMA requires federal agencies to follow the guidelines outlined in NIST 800-53 when developing their security policies and procedures. The agencies must conduct regular security assessments and document the results, perform risk assessments, and implement the necessary security controls to mitigate risks. FISMA also requires regular reporting to senior leaders about the agency’s security posture.
NIST 800-53 plays a crucial role in the FISMA compliance process by providing a framework for federal agencies to assess and manage their cybersecurity risks. The publication provides detailed guidelines that enable agencies to develop effective security policies, procedures, and systems that meet the standard set by FISMA.
How Does NIST 800-53 Relate to FedRAMP?
NIST 800-53 and FedRAMP are two important frameworks that play a vital role in enhancing the cybersecurity posture of the federal government. NIST 800-53 is a set of guidelines and controls that are used by federal agencies to establish and maintain an effective security program. FedRAMP, on the other hand, is a government-wide program that provides a standardized approach to security assessment, authorization, and continuous monitoring of cloud-based services. Initially, any cloud service provider that wanted to do business with the federal government had to become FedRAMP authorized. Lately, however, many private sector businesses are choosing FedRAMP authorized cloud service providers, as they represent the pinnacle of data security and protection.
FedRAMP builds upon the security controls outlined in NIST 800-53 and provides a structured approach to assessing and authorizing cloud-based services for use by the federal government. The program aims to streamline the assessment and authorization process for cloud-based services, reduce duplication of effort, and improve security and transparency. Cloud service providers must demonstrate compliance with the security controls outlined in NIST 800-53 before they can be authorized for use by federal agencies.
The relationship between NIST 800-53 and FedRAMP is critical because the former provides the foundational security controls that are used by the latter to assess and authorize cloud-based services. FedRAMP uses a modified version of the NIST 800-53 security control catalog, known as FedRAMP Moderate, which includes additional controls specific to cloud-based services. By using a common set of security controls, federal agencies can ensure that their cloud-based services are adequately protected and meet the same security standards as their on-premises systems.
