NIST SP 800-18r1 is a comprehensive guide designed to help federal agencies build and maintain a secure, reliable, and efficient information system to protect their information assets from threats such as unauthorized access, use, disclosure, destruction, modification, or destruction.
A critical area in developing the System Security Plan is determining what is in and out of scope. The section on Scoping Guidance provided key considerations to utilize when determining how the baseline controls should be applied to an organization. The guidance also reiterated the importance of including a rationale for the type of considerations that were made. A documented rationale to support critical decisions is important for the Authorizing Official to understand and will be reviewed in situations where errors occur or threats are realized.
The Guidelines for Developing Federal Information System Security Plans emphasize that in the system security plan, information types and information systems must be classified according to the FIPS199 registry for security, which affects the prioritization of asset types and achieves cost-effective information security protection.
A system security plan helps an organization to identify security measures. According to the document, a system security plan is a dynamic document that requires periodic review and revision, as well as action plans and milestones for implementing security controls.FIPS 199 helps an organization determine the identification of threats and vulnerabilities in its system security plan, and it can be used to develop remediation methods and update the security plan. In addition, the system security plan helps the organization train its managers, users, and system administrators on how to use the system securely and demonstrates how the organization can effectively respond to any security incidents.
I think the FISMA(Federal Information Security Management Act) requires that all federal agencies develop, document, and implement an agency-wide information security program. This program is used to provide information security for all information and information systems that are used for business operations and agency assets.
This information system security plan should include a summary of all the security requirements and security controls that are in place to support these requirements. The system security plan documents require periodic review, recertification, modification, and plans of action to implement their supporting controls. The organization should also have procedures in place to determine who reviews the plan, updates the plan, and follows up on the established controls. The plan must also be accredited and certified. The certification agent must ensure that the program is in line with FIPS 199 security category: “the threat and vulnerability identification and initial risk determination are identified and documented in the system the security plan, risk assessment, or equivalent document”. The security plan is based on FIPS 199, FIPS 200, and the SP 800-53 document. It must consist of a risk assessment, ongoing monitoring, point of action and milestones and provide guidance for configuration management. It must also have a process to ensure completeness and accuracy.
NIST SP 800-18r1 is designed to provide federal government agencies with a framework and guidance for developing and implementing information systems security programs. The guidelines are part of NIST’s Special Publication 800 series, which focuses on information security and privacy protection.
The primary goal of NIST SP 800-18r1 is to help federal government agencies identify and manage security risks to their information systems. It provides a structured approach to ensure that security programs can fully cover an organization’s information assets and meet relevant regulatory and policy requirements.
Hi Lakshmi, I agree that risk management is not designed to eliminate all risks. By its own nature some risks can have a low probability of occurrence or a low impact, so it would not be advisable from an economic point of view to expend resources eliminating these risks. Risk management also involves forecasting and evaluating the potential risks associated with day-to-day operations, while actively identifying ways to reduce them or minimize their impact on the business.
The NIST SP 800-18r1 is not only targeting the organizations that have regularity compliance requirements from the federal government. It also targets the program managers, system owners, and security personnel in any organization, as well as the users within the organization. The NIST SP 800-18r1 is designed to provide guidelines on how to prepare a system security plan and it can be adapted to fit variety of organizations.
The most attractive to me is Ongoing System Security Plan Maintenance. Once the information system security plan is developed, it is important to periodically assess the plan, review any change in system status, functionality, design, etc., and ensure that the plan continues to reflect the correct information about the system. This documentation and its correctness are critical for system certification activity. Sometimes this crucial step may be overlooked as they don’t think about what will happen in the future if the information is not modified in time. hen it comes to maintaining a smoothly operating network and preventing a malicious cyberattack, getting the routine basics right is key.
For instance, an estimated average of 1 in 3 breaches is caused by unpatched vulnerabilities, which are known flaws in software or hardware that the business, for whatever reason, fails to fix before attackers leverage it to breach their environment. This is just one example of a routine maintenance item that could make a significant difference to an organization’s cybersecurity posture.
Boundary of the system is something I’m interested in. The process of uniquely allocating information resources for an information system defines the security boundaries of that system. Agencies have a great deal of flexibility in determining what is an information system, that is, a primary application or a general support system. If a group of information resources is identified as an information system, the resource should generally be under the same direct management control. An information system may also contain multiple subsystems. A subsystem is a major subdivision or component of an information system. Subsystems typically fall under the same administrative authority and are included in a single system security plan. A system security plan reflects the breakdown of the information system and assigns adequate security controls to each subsystem component.
The goal of system security planning is to improve the protection of information system resources, and the protection of the system must be recorded in the system security plan. The purpose of the system security plan is to provide an overview of the system security requirements and describe the controls implemented or planned to be implemented to meet these requirements. The system security plan also describes the responsibilities and expected behavior of all individuals accessing the system. A system security plan should be viewed as a document of a structured process for planning adequate, cost-effective security protection for a system. It should reflect the input of the various managers involved in the system, including the information owner, the system owner, and the Senior Agency Information Security Officer (SAISO).
The security plan for an information system should contain detailed information about the classification of the data stored, the assignment of ownership of the system, and information to ensure that everyone has a proper understanding of the functions, security measures, permissions, etc., of their respective positions. The development of a security plan will allow for a complete security overview of the system and help to ensure that all three security objectives (confidentiality, integrity, and availability) are implemented.

The NIST SP 800-18r1 is designed to provide guidelines on how to prepare a system security plan and it can be adapted to fit variety of organizations.
The most attractive to me is Ongoing System Security Plan Maintenance. Once the information system security plan is developed, it is important to periodically assess the plan, review any change in system status, functionality, design, etc., and ensure that the plan continues to reflect the correct information about the system. This documentation and its correctness are critical for system certification activity. Sometimes this crucial step may be overlooked as they don’t think about what will happen in the future if the information is not modified in time. hen it comes to maintaining a smoothly operating network and preventing a malicious cyberattack, getting the routine basics right is key.
For instance, an estimated average of 1 in 3 breaches is caused by unpatched vulnerabilities, which are known flaws in software or hardware that the business, for whatever reason, fails to fix before attackers leverage it to breach their environment. This is just one example of a routine maintenance item that could make a significant difference to an organization’s cybersecurity posture.
Boundary of the system is something I’m interested in. The process of uniquely allocating information resources for an information system defines the security boundaries of that system. Agencies have a great deal of flexibility in determining what is an information system, that is, a primary application or a general support system. If a group of information resources is identified as an information system, the resource should generally be under the same direct management control. An information system may also contain multiple subsystems. A subsystem is a major subdivision or component of an information system. Subsystems typically fall under the same administrative authority and are included in a single system security plan. A system security plan reflects the breakdown of the information system and assigns adequate security controls to each subsystem component.
The goal of system security planning is to improve the protection of information system resources, and the protection of the system must be recorded in the system security plan. The purpose of the system security plan is to provide an overview of the system security requirements and describe the controls implemented or planned to be implemented to meet these requirements. The system security plan also describes the responsibilities and expected behavior of all individuals accessing the system. A system security plan should be viewed as a document of a structured process for planning adequate, cost-effective security protection for a system. It should reflect the input of the various managers involved in the system, including the information owner, the system owner, and the Senior Agency Information Security Officer (SAISO).
