What’s Covered in NIST SP 800-53: Three Classes of Information Systems

NIST Publication 800-53 categorizes information systems into three classes:

Operational Systems: These systems are used to carry out day-to-day tasks within an organization. They are typically designed to automate routine processes and support business functions. Examples of operational systems include human resource management systems, supply chain management systems, and customer relationship management systems.

Management Systems: These systems are used by management to control and monitor an organization’s activities. They typically provide decision-making support and enable managers to plan, allocate resources, and monitor progress. Examples of management systems include financial management systems, project management systems, and risk management systems.

Technical Systems: These systems are used to support the delivery of IT services. They are typically responsible for managing the underlying infrastructure that supports an organization’s applications and data. Examples of technical systems include network infrastructure, servers, storage devices, and security systems.

While these three classes of information systems serve different purposes and play distinct roles in supporting an organization’s operations, they are often interconnected and rely on one another to function effectively.

NIST SP 800-53 Assessment Levels for Information Systems

The NIST 800-53 features three assessment levels for information systems. These assessment levels are designed to help federal information systems and organizations determine the appropriate level of security and privacy controls needed to protect their information and assets. The assessment levels are:

Baseline: This level includes a set of security and privacy controls that are considered the minimum necessary for federal information systems and organizations to operate effectively while ensuring a basic level of security and privacy.

Moderate: This level includes additional security and privacy controls that are required for systems that process moderate levels of sensitive information, such as financial or healthcare data.

High: This level includes the most stringent security and privacy controls and is required for systems that process high levels of sensitive information, such as classified information or personally identifiable information (PII).

NIST 800-53 Control Families

NIST 800-53 is organized into 23 control families, each covering a specific aspect of information security and privacy. These families include access control, awareness and training, audit and accountability, contingency planning, identification and authentication, incident response, maintenance, media protection, physical and environmental protection, planning, risk assessment, and system and information integrity, among others.

Categories of Controls

Each NIST 800-53 control family contains a set of controls, categorized as either management, operational, or technical controls, the same categories assigned to information systems. Management controls are designed to provide an overall framework for information security management, while operational controls involve processes and procedures for implementing security measures. Technical controls are the actual security mechanisms, including hardware, software, and firmware.

The controls are organized into 20 families that cover a wide range of security-related topics, such as access control, audit and accountability, incident response, and system and information integrity. Each family includes a set of controls that specify the minimum security requirements for that particular area.

The controls are meant to be flexible and adaptable, so organizations can tailor them to meet their specific security needs. They are regularly updated to address new security threats and technologies.

Updates and Patches: Keeping information systems up to date with the latest security patches and software updates will help protect against new and emerging threats.

Regular Audits: Conducting regular audits can ensure that the organization is meeting all of the necessary requirements for NIST 800-53 compliance.

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.
