The process of selecting security controls when using a three-tier risk management approach of organizations (Tier 1), tasks/business processes (Tier 2), and information systems (Tier 3) is described in NIST SP 800 53r4. This three-tier approach allows for continuous improvement of risk-related activities and makes communication with all stakeholders in the organization easier. After risk categorization of the information system, security controls need to be selected. When the data is classified according to the CIA Triad, the organization can reflect on the risk mitigations and will have a better understanding of the risk methodology, and it is also interesting to note that external service providers can be used to satisfy certain to help the organization to meet its security needs.
The document was the discussion of multitiered risk management and the document notes that multitiered risk management helps to integrate the risk management process throughout the organization, as well as to ensure risk management acknowledges mission and business concerns. The tiers are as follows: organization (tier 1), mission and business processes (tier 2), and information systems (tier 3). Tier 1 stood out to me, as this tier handles the highest-level management of risk, which includes prioritizing organizational missions and business functions, driving investment strategies and funding, promoting cost-effective solutions, and ensuring all these components are consistent with the strategic goals and objectives of the organization. This is an absolutely essential function that many organizations, especially those that treat risk management as a separate entity from the enterprise, often ignore. Organizations must integrate risk management into their business processes, and the multitiered risk management approach ensures that business operations and risk management are intertwined rather than siloed. Siloing these functions results in risk management not aligning with the organizational and strategic goals of the enterprise, which results in the risk management processes failing or not meeting the predetermined risk management standards.
Security and privacy controls for federal information systems and organizations are important measures to ensure the safe, reliable, and efficient operation of federal agency information and information systems. By following the controls and requirements in NIST SP 800-53 and combining with the actual situation and needs of the organization, the development of personalized security policies and control measures can effectively reduce the risk and impact of security incidents and ensure the normal operation and development of the organization.
NIST 800 53r4 The goal of Security and Privacy Controls for Federal Information Systems and Organizations is to provide guidance to its partners on selecting organizational security controls in accordance with FIBS Publication 200 and the Federal Minimum Security Requirements. This document provides an outline of a risk management framework, which is an ongoing process. it security professionals should categorize, select, implement, assess, authorize, and monitor different risks. By understanding the framework, IT security professionals can implement appropriate security controls for each type of risk.
NIST 800 53r4 Security and Privacy Controls for Federal Information Systems and Organizations provides federal agencies with detailed guidance on how to select and implement information security and privacy controls. These controls are designed to protect sensitive information from unauthorized access, use, disclosure, damage, modification, or destruction. By following the guidance in NIST SP 800-53r4, Federal agencies can establish a robust information security and privacy protection framework to protect their critical information and assets from a variety of threats and risks.
NIST SP 800-53r4 provides a comprehensive framework of security controls that encompasses multiple aspects of access control, identity management and authentication, security assessment and authorization, system and communications protection, auditing, and monitoring. These controls are designed to protect the confidentiality, integrity, and availability of information systems. The importance of privacy protection is also specifically emphasized and a series of privacy controls are provided. These measures cover personal information protection, privacy impact assessment, privacy training and awareness-raising to ensure that personal information is lawfully collected, used, stored and shared.
One of the key points of the NIST special publication 800-53r4 is the New Development and Legacy Systems section. There are two different views of new development and heritage. For new development systems, the security control selection process is applied from the perspective of requirements definition. The organization makes security classifications, incorporates them into security plans, and implements them into the system development lifecycle. This perspective is for systems that do not yet exist. If the information system already exists, the organization’s security control selection process is applied from the perspective of gap analysis. This legacy information system can apply the security control selection process from different analytical perspectives.
Key elements of NIST SP 800-53r4:
1.Control Families: The document organizes the security and privacy controls into families, such as Access Control, Audit and Accountability, Awareness and Training, Configuration Management.
2.Control Baselines: NIST SP 800-53r4 provides multiple baselines for agencies to select from, based on their mission requirements and the sensitivity of their information.
3.Implementation Guidance: For each control, the document provides detailed implementation guidance, including the steps agencies should take to implement the control, as well as any associated policies, procedures, or technologies that may be useful.
4.Assessment and Authorization: The guide also covers the process for assessing and authorizing information systems, including the conduct of security assessments, the development of security plans, and the authorization decision-making process.
5.Privacy Considerations: In addition to traditional security controls, NIST SP 800-53r4 also includes a focus on privacy controls, addressing the protection of personally identifiable information and other sensitive data.
The operation of information and communication systems (ICTs) depends on an interconnected supply chain ecosystem distributed across the globe, comprising various entities such as purchasers, system integrators, suppliers and external service providers, the design, production, distribution, deployment and use of products and services, as well as soft environments such as technology, law and policy.By following the guidance of NIST SP 800-53r4, federal agencies can establish a robust framework for information security and privacy protection
Multi-layered risk management decomposes risks into different layers or dimensions, such as strategic layers, operational layers, project layers, etc. This hierarchical management helps organizations better understand and manage risks at different levels and develop appropriate control measures based on the characteristics and impacts of risks.
The integration of a three-tier risk management approach, as outlined in NIST SP 800-53r4, encompassing organization-level (Tier 1), task/business process-level (Tier 2), and information system-level (Tier 3) risks, is crucial for ensuring the secure, reliable, and efficient operation of federal information systems. This tiered framework not only facilitates continuous improvement in risk-related activities but also enhances communication among stakeholders. After categorizing risks within the information system, the selection of appropriate security controls becomes paramount. Classifying data based on the CIA Triad (Confidentiality, Integrity, Availability) allows organizations to deeply reflect on risk mitigations and gain a deeper understanding of the risk methodology. Furthermore, the utilization of external service providers can significantly assist in meeting specific security needs, thus bolstering the organization’s overall security posture. By adhering to the controls and requirements specified in NIST SP 800-53 and customizing them to fit the unique context and requirements of the organization, personalized security policies and control measures can be developed. This approach effectively minimizes the risk and impact of security incidents, ensuring the smooth operation and sustained development of the organization.
NIST 800 53r4 includes controls for protecting information systems. This control protects information systems from different levels of operations, technology and management. The purpose of NIST 800 53r4 is to maintain the confidentiality, integrity, and availability of information systems. It also includes a risk management framework. It includes a 6-step process. The first step is to classify the information system. Then, Step 2 Select appropriate controls to protect the information system. Step 3 includes implementing these controls. Then, evaluate the security controls as part of Step 4. Step 5 Include authorizing the controls. The final step 6 includes continuous monitoring of the process.
NIST 800-53 R4 includes the controls to secure the information systems. This controls secures the information systems from different levels as at the Operational, technical and management level. The purpose of the NIST 800-53 R4 is to maintain the confidentiality, integrity, and availability of the information system. It also includes the Risk Management Framework. Which includes 6 steps process. Step 1 is to categorize of the information systems. Then step 2 select the appropriate controls to secure the information systems. Step 3 includes implementing those controls. Security controls then get assessed as part of the step 4. Step 5 includes authorizing those controls. The final step 6 includes to continuous monitoring of that process.
NIST 800-53r4 outlines comprehensive security and privacy controls for federal information systems and organizations. One particularly impactful aspect is the emphasis on continuous monitoring and assessment of security controls. This approach recognizes that cybersecurity is not a one-time effort but an ongoing process that requires constant attention and adaptation to new threats. By prioritizing continuous monitoring, organizations can better detect and respond to security incidents, ultimately enhancing the overall security posture.
This publication details the second step of the NIST Cybersecurity Risk Framework: after categorizing systems into low, medium, and high impact levels, how to target and select the appropriate security controls. The book lists seventeen control families and provides a list of controls that should be implemented for each type of impact level system. This assessment process is designed to establish a baseline of security controls that will effectively protect the information system from all types of threats from internal, external, or human sources. It should be noted that some systems may require more stringent controls than those recommended in the baseline, depending on multiple factors such as the data handled by the system, the content stored and the nature of the business. The exercise therefore requires regular review and flexible adjustment of security controls in the light of the actual situation to ensure that system risks are minimized.
Multi-layer risk management is a process and method of security control, dividing risk into different levels or dimensions, the main purpose is to reduce risk, and consider all aspects of the operation process. What risks arise in day-to-day operations and what it will take for the organization to get back to normal. Risk is assessed at different levels of the organization and is therefore critical to aligning processes with business objectives.
After reading NIST 800-53r4, I have a better understanding of information security and privacy protection. This standard not only focuses on the technical aspects of security, but also ensures a full range of security and privacy from multiple dimensions, including management, personnel, and physical environment.
The standard provides 53 subcontrol sets that cover all aspects from risk assessment to safeguarding system and data integrity. It requires organizations to focus not only on technical security, but also to develop and implement security policies and procedures, conduct security vetting for hiring and separation of personnel, and provide employee training and education.
Additionally, controls in the physical environment are important, including strict control of physical access and addressing potential threats.
In summary, NIST 800-53r4 is not just a technical standard, but a comprehensive security framework. It provides an important reference for understanding and addressing information security and privacy protection challenges.
NIST SP 800-53r4, “Security and Privacy Controls for Federal Information Systems and Organizations,” is a comprehensive guide that provides a framework for federal agencies to select and implement security and privacy controls for their information systems and organizations.
Here are some key elements of NIST SP 800-53r4:
Security and Privacy Controls Catalog: The document includes a catalog of security and privacy controls that agencies can use to address specific security requirements. These controls are organized into families such as access control, audit and accountability, awareness and training, configuration management, identification and authentication, incident response, maintenance, media protection, personnel security, physical and environmental security, planning, program management, recovery, risk assessment, and system and services acquisition.
Control Baselines: NIST SP 800-53r4 defines several control baselines that agencies can adopt based on their specific needs and risk tolerances. These baselines include a low baseline, a moderate baseline, and a high baseline, each with a corresponding set of security and privacy controls.
Integration with Other Frameworks: The document provides guidance on how to integrate NIST SP 800-53r4 with other frameworks and standards, such as the Risk Management Framework (RMF) and the Federal Information Processing Standards (FIPS).
Updated Controls and Enhancements: NIST SP 800-53r4 includes updated controls and enhancements to address evolving cyber threats and best practices. These updates reflect lessons learned from past incidents, new security technologies, and evolving privacy requirements.
Focus on Privacy: In addition to traditional security controls, the document also includes a focus on privacy controls to address the protection of personally identifiable information (PII) and other sensitive data.
To implement the controls outlined in NIST SP 800-53r4, agencies are expected to conduct a thorough risk assessment, develop a security plan, and implement the appropriate controls based on their risk tolerance and business needs. Agencies are also encouraged to continuously monitor and evaluate their security controls to ensure they remain effective and up to date.
NIST 800-53r4 is a standard document published by the National Institute of Standards and Technology (NIST) in the United States. Its full name is “Security and Privacy Controls for Federal Information Systems and Organizations,” also known as “Security and Privacy Controls for Federal Information Systems and Organizations.”.
This standard document aims to provide federal government agencies and organizations with a comprehensive set of security and privacy control measures to protect the security and privacy of their information systems and data. It provides a series of security and privacy control objectives, requirements, and guidelines to help organizations establish, implement, supervise, and maintain security and privacy controls for information systems.
The NIST 800-53r4 standard document contains a series of control measures covering various aspects of information system security and privacy, including access control, identity authentication, risk management, event response, physical security, network security, data protection, etc. These control measures aim to help organizations establish a comprehensive information system security and privacy management framework to address various threats and risks.
The NIST 800-53r4 standard document is the benchmark for security and privacy control for federal government agencies and organizations in the United States, and is widely used in other industries and organizations, especially those that have business dealings with the federal government. It provides a set of universal best practices and guidelines to help organizations establish and maintain the security and privacy of information systems to protect sensitive information and data from unauthorized access, leakage, and damage.
One of the key points from this publication is from the purpose of security and privacy controls, which is providing guidelines in stipulating security controls for establishments and supporting executive organizations. In order to attain information systems security, it is required to: enable a consistent method in specifying security controls for information systems; provide a firm collection of information regarding security controls in order to meet current information needs; provide groundwork for assessment procedures to determine security control efficiency, and communicate with organizations to provide knowledge in discussing risk management ideas.
The NIST SP 800-53r4 establishes a powerful framework for information security and privacy protection for federal agencies. The supply chain of operating information and communication systems is distributed globally and includes various entities such as purchasers, system integrators, suppliers, and external service providers, products and services designed, produced, distributed, deployed, and used, as well as soft environments such as technology, laws, and policies.
This publication lists various security controls for federal systems to help protect them from malicious cyberattacks, natural disasters, structural failures, and human error. The controls listed are intended to be technology-neutral, meaning they focus on the basic safeguards needed to protect information during processing, storage, and transmission. A key feature in the reading is the baseline. Before specifying which security controls are to be implemented on a system, a baseline of security controls must be established. This baseline is based on the FIPS 200 impact level assigned to a particular system. When determining the baseline for an information system, certain factors need to be considered, such as the physical location where the information system is located, the type of information being stored/processed, the nature of the operations being performed by the organisation, or the type of threats facing the organisation. Organisation. Once a baseline is established, appropriate security controls can be customised around that baseline to properly protect the information.
The key is to choose the appropriate security baseline to ensure that the equipment and systems associated with the enterprise network environment have basic protection capabilities. A security baseline is a set of minimum security standards and configuration benchmarks defined for information systems to meet the most basic security requirements.
In order to establish and maintain these security baselines, the enterprise information or technology department should establish a complete security baseline management system from a macro perspective. The system should clarify the responsibilities of the parties, specify the requirements for the use of baselines, and implement monitoring and inspections to ensure their effective implementation. Responsibilities need to be assigned to the departments responsible for baseline development, revision, and review, as well as to the operators who perform the baseline configuration, such as managers of network equipment, servers, middleware, and databases. At the same time, a monitoring mechanism should be established to check the security baseline configuration of the device.
In addition, the regime should specify the requirements for the use of the Internet and internal networks in the baseline, as well as the applicable requirements for the baselines of the different levels of the system. Baseline requirements must also be specified for scenarios such as new online systems, third-party system access, and important system changes. In the event of a conflict between business requirements and baseline standards, an approval process and alternative treatment should be developed and clearly specified in the baseline usage requirements. Through these measures, enterprises can ensure the effective implementation of security baselines, thereby improving the overall security of information systems.
One of the key points from this publication is from the purpose of security and privacy controls, which is providing guidelines in stipulating security controls for establishments and supporting executive organizations. In order to attain information systems security, it is required to: enable a consistent method in specifying security controls for information systems; provide a firm collection of information regarding security controls in order to meet current information needs; provide groundwork for assessment procedures to determine security control efficiency, and communicate with organizations to provide knowledge in discussing risk management ideas.
Describe how to select a security control baseline, customize baseline security controls to appropriately modify controls and align them more closely with specific conditions within the organization; Organizations can use requirement definition methods or gap analysis methods to select security controls and control enhancements to supplement the initial baseline; Enhance information security without changing control choices; Organizations can use recommended priority codes related to each security to specify control in the baseline to help make ranking decisions for control implementation.
NIST SP 800 53r4 provides some useful ideas and methods on how to provide information security requirements/requirements of federal information systems and IT systems. Based on the current information security practice, the standard provides a comprehensive and detailed security control catalog for federal information systems and organizations. To protect the safe operation of the organization, the security control selection process is provided – a consistent, comparable and repeatable approach. Describes how specialized control sets or overlays can be tailored for a specific type of mission/business function, technology, or operating environment; Provides a set of privacy controls to help organizations enforce federal laws, policies, regulations, guidelines, and standards related to privacy.
One of the key points I found was the section on security control baseline and tailoring controls to business needs based on risk. Determining the control baseline appears to be comprehensive and is based on a series of assumptions, and provides a separate list of assumptions to help determine if additional safety controls are needed. This also reminded me of the reading from the book and the need for there to be a sort of controls-for-the-controls in order to mitigate insider threats to the system. IT security itself is a long-term capital consumption project, cost and benefit control adjustment is very important.The set of assumptions in NIST 800-53r4 can help organizations make good predictions.
There are 3 approaches to implementing controls for security and privacy controls, for example: generic control implementation, system-specific control implementation, and hybrid control implementation.
Control Implementation – defines the scope of application of the control, the shared nature or inheritance of the control, and the responsibility for control development.
System-specific controls-primarily the responsibility of the system owner and authorized officials for a given system. Implementing system-specific controls may pose a risk if the control implementation is not interoperable with common controls.
Hybrid Controls-Risks can be introduced if the responsibilities for implementation and ongoing management of the common and system-specific parts of the control are not clear.

A key feature in the reading is the baseline. Before specifying which security controls are to be implemented on a system, a baseline of security controls must be established. This baseline is based on the FIPS 200 impact level assigned to a particular system. When determining the baseline for an information system, certain factors need to be considered, such as the physical location where the information system is located, the type of information being stored/processed, the nature of the operations being performed by the organisation, or the type of threats facing the organisation. Organisation. Once a baseline is established, appropriate security controls can be customised around that baseline to properly protect the information.

The key is to choose the appropriate security baseline to ensure that the equipment and systems associated with the enterprise network environment have basic protection capabilities. A security baseline is a set of minimum security standards and configuration benchmarks defined for information systems to meet the most basic security requirements.
In order to establish and maintain these security baselines, the enterprise information or technology department should establish a complete security baseline management system from a macro perspective. The system should clarify the responsibilities of the parties, specify the requirements for the use of baselines, and implement monitoring and inspections to ensure their effective implementation. Responsibilities need to be assigned to the departments responsible for baseline development, revision, and review, as well as to the operators who perform the baseline configuration, such as managers of network equipment, servers, middleware, and databases. At the same time, a monitoring mechanism should be established to check the security baseline configuration of the device.
In addition, the regime should specify the requirements for the use of the Internet and internal networks in the baseline, as well as the applicable requirements for the baselines of the different levels of the system. Baseline requirements must also be specified for scenarios such as new online systems, third-party system access, and important system changes. In the event of a conflict between business requirements and baseline standards, an approval process and alternative treatment should be developed and clearly specified in the baseline usage requirements. Through these measures, enterprises can ensure the effective implementation of security baselines, thereby improving the overall security of information systems.

One of the key points from this publication is from the purpose of security and privacy controls, which is providing guidelines in stipulating security controls for establishments and supporting executive organizations. In order to attain information systems security, it is required to: enable a consistent method in specifying security controls for information systems; provide a firm collection of information regarding security controls in order to meet current information needs; provide groundwork for assessment procedures to determine security control efficiency, and communicate with organizations to provide knowledge in discussing risk management ideas.

Describe how to select a security control baseline, customize baseline security controls to appropriately modify controls and align them more closely with specific conditions within the organization; Organizations can use requirement definition methods or gap analysis methods to select security controls and control enhancements to supplement the initial baseline; Enhance information security without changing control choices; Organizations can use recommended priority codes related to each security to specify control in the baseline to help make ranking decisions for control implementation.

NIST SP 800 53r4 provides some useful ideas and methods on how to provide information security requirements/requirements of federal information systems and IT systems. Based on the current information security practice, the standard provides a comprehensive and detailed security control catalog for federal information systems and organizations. To protect the safe operation of the organization, the security control selection process is provided – a consistent, comparable and repeatable approach. Describes how specialized control sets or overlays can be tailored for a specific type of mission/business function, technology, or operating environment; Provides a set of privacy controls to help organizations enforce federal laws, policies, regulations, guidelines, and standards related to privacy.
Yue Ma says
One of the key points I found was the section on security control baseline and tailoring controls to business needs based on risk. Determining the control baseline appears to be comprehensive and is based on a series of assumptions, and provides a separate list of assumptions to help determine if additional safety controls are needed. This also reminded me of the reading from the book and the need for there to be a sort of controls-for-the-controls in order to mitigate insider threats to the system. IT security itself is a long-term capital consumption project, cost and benefit control adjustment is very important.The set of assumptions in NIST 800-53r4 can help organizations make good predictions.
Hao Li says
There are 3 approaches to implementing controls for security and privacy controls, for example: generic control implementation, system-specific control implementation, and hybrid control implementation.
Control Implementation – defines the scope of application of the control, the shared nature or inheritance of the control, and the responsibility for control development.
System-specific controls-primarily the responsibility of the system owner and authorized officials for a given system. Implementing system-specific controls may pose a risk if the control implementation is not interoperable with common controls.
Hybrid Controls-Risks can be introduced if the responsibilities for implementation and ongoing management of the common and system-specific parts of the control are not clear.
