The FIPS 199 formula, established by the National Institute of Standards and Technology (NIST), is a guideline utilized in the federal information security framework to categorize the impact of potential threats on information systems. Specifically, FIPS 199 defines the requirements for security categorization based on the potential impact of a breach on the confidentiality, integrity, and availability of information. The formula assesses these impacts on three levels—low, moderate, and high—across the three security objectives.
This categorization plays a crucial role in the development of security controls by federal agencies, ensuring appropriate measures are implemented to protect sensitive information. The ultimate goal is to manage risks effectively while ensuring compliance with federal security standards. Understanding and applying the FIPS 199 formula is essential for organizations seeking to align with federal regulations and improve their information security posture.
Understanding FIPS 199 Formula
1. Overview of FIPS 199
Federal Information Processing Standards (FIPS) are publicly announced standards developed by the U.S. federal government for use in computer systems. FIPS 199 specifically addresses the security categorization of federal information and information systems. The document sets forth the importance of classifying data based on its sensitivity and the potential impact of unauthorized access or alterations.
2. Purpose and Need for the FIPS 199 Formula
In an era where data breaches and cyber threats are prevalent, FIPS 199 provides a structured approach for organizations to evaluate their information systems. The significance of FIPS 199 extends to:
- Risk Management: It helps organizations identify vulnerabilities and determine appropriate levels of security measures.
- Compliance: Federal agencies must follow this standard to comply with the Federal Information Security Modernization Act (FISMA).
- Resource Allocation: The categorization helps allocate resources efficiently and effectively to mitigate risks.
3. Elements of the FIPS 199 Formula
FIPS 199 focuses on three core security objectives:
- Confidentiality: Ensuring that information is not disclosed to unauthorized individuals.
- Integrity: Protecting information from being altered or destroyed by unauthorized individuals.
- Availability: Ensuring that authorized users have access to information and associated assets when needed.
3.1 Security Categories
The FIPS 199 formula categorizes information systems based on the potential impact of loss or compromise:
- Low Impact: Limited adverse effect on organizational operations, assets, or individuals.
- Moderate Impact: Serious adverse effect on organizational operations, assets, or individuals.
- High Impact: Severe or catastrophic adverse effect.
4. Applying the FIPS 199 Formula
The application of the FIPS 199 formula involves a systematic evaluation process:
- Identify the information types and their security requirements.
- Assess the impact of a loss of confidentiality, integrity, or availability.
- Assign values (low, moderate, high) based on the potential impacts.
Example Evaluation
Consider a federal agency managing personal health information (PHI). In this example:
- If compromised, losing confidentiality could have a high impact due to legal ramifications.
- Integrity loss could also be rated high, as altered health records could jeopardize patient safety.
- The availability rating might be moderate, as access is critical but can be managed through alternative methods.
5. Compliance and Impact of FIPS 199
Compliance with FIPS 199 ensures that agencies not only protect sensitive information but also uphold public trust. Not adhering to FIPS 199 guidelines can lead to data breaches, financial loss, or legal repercussions. Furthermore, using the FIPS 199 framework enables organizations to stay ahead in the ever-evolving landscape of cybersecurity threats.
