FIPS Pub 199, also known as the Federal Information Processing Standards Publication 199, is a standard published by the National Institute of Standards and Technology (NIST). Used to guide the U.S. federal government on how to securely classify its information systems. The standard was released in 2004 to provide a unified approach to assessing and managing security risks to federal information systems.
The core concept of FIPS Pub 199 is the Security category, which is based on three key security attributes: Confidentiality, Integrity, and Availability. Each attribute has three possible impact levels: Low, Moderate, and High. Through the combination of these attributes and levels, a unique security category can be identified for each information system.
Specifically, FIPS Pub 199 requires organizations to first identify all types of information processed within their information systems, such as private information, contractor sensitive information, proprietary information, etc. Each information type is then assessed for its potential impact in terms of confidentiality, integrity, and availability. Then, according to the “take high” principle, the highest impact level of each attribute is selected as the overall security category of the information system.
Finally, FIPS Pub 199 provides a generic expression for a security category (SC), namely SC={(confidentiality, impact level), (integrity, impact level), (availability, impact level)}. This expression can be used to describe the security requirements of an information system or information type.
By following the guidelines of FIPS Pub 199, organizations can develop more specific and consistent security policies and management measures for their information systems, thereby improving the security of their systems and reducing potential risks.
Security plans for their information systems should be the necessity for agencies to adopt a set of minimum security controls, as mandated. These controls are essential for safeguarding the confidentiality, integrity, and availability of federal information systems against potential security threats.
System security planning is underscored as a critical activity aligned with the system development life cycle (SDLC). Security plans should be revisited and updated in response to system events to ensure they accurately represent the current state of the system. The system security plan should outline the security requirements of the information system and detail the security controls that are in place or planned to meet these requirements. Additionally, the plan may include references to other vital security-related documents, such as risk assessments, plans of action and milestones, accreditation decision letters, privacy impact assessments, contingency plans, configuration management plans, security configuration checklists, and system interconnection agreements
