SI-15: Information Output Filtering

RMF Control SI-15: Information Output Filtering requires organizations to validate information before it is output to users or systems. This is important for protecting information systems from unauthorized access and disclosure.

Supplemental Guidance

The Risk Management Framework (RMF) is a cybersecurity framework that provides a process for managing cybersecurity risk to systems and organizations. RMF Control SI-15: Information Output Filtering is one of the controls in the SI family, which addresses system and information integrity.

Information output filtering is the process of validating information before it is output to users or systems. This can help to prevent unauthorized access and disclosure of information, as well as the transmission of malicious code.

Benefits of Implementing RMF Control SI-15

There are a number of benefits to implementing RMF Control SI-15, including:

• Improved security posture: By validating information before it is output to users or systems, organizations can improve their overall security posture and reduce the risk of unauthorized access, disclosure, and malware infection.
• Reduced risk of data breaches: Information output filtering can help to prevent data breaches by preventing the unauthorized disclosure of sensitive information.
• Improved compliance: Many regulations require organizations to have information output filtering in place. By implementing RMF Control SI-15, organizations can improve their compliance with these regulations.

How to Implement RMF Control SI-15

To implement RMF Control SI-15, organizations should:

1. Identify all systems and applications that generate information output.
2. Assess the risks to each system and application. This assessment should consider the likelihood and impact of unauthorized access, disclosure, or malware infection.
3. Implement controls to mitigate the risks to each system and application. Controls may include input validation, output filtering, and anomaly detection.
4. Monitor the systems and applications to detect and respond to attacks.

Examples of Information Output Filtering Controls

Some examples of information output filtering controls include:

• Input validation: Input validation is used to ensure that input data is valid and does not contain malicious code.
• Output filtering: Output filtering is used to remove sensitive information from output data.
• Anomaly detection: Anomaly detection is used to detect unusual or suspicious activity in output data.

Conclusion

RMF Control SI-15: Information Output Filtering is an important control that can help organizations to improve their security posture, reduce the risk of data breaches, and improve their compliance. By implementing information output filtering controls, organizations can protect their information systems from unauthorized access, disclosure, and malware infection.

Additional Tips for Implementing RMF Control SI-15

• Use a risk-based approach to information output filtering: Organizations should use a risk-based approach to information output filtering to ensure that the most critical systems and applications are filtered first.
• Involve stakeholders in the information output filtering process: Organizations should involve stakeholders, such as IT staff, security staff, and business owners, in the information output filtering process. This will help to ensure that the information output filtering plan is aligned with the organization’s business needs and security requirements.
• Regularly review and update the information output filtering plan: Organizations should regularly review and update the information output filtering plan to ensure that it is effective and up-to-date.
