Control statement
Validate information output from the following software programs and/or applications to ensure that the information is consistent with the expected content: [Organization-defined: software programs and/or applications].
Discussion
Certain types of attacks, including SQL injections, produce output results that are unexpected or inconsistent with the output results that would be expected from software programs or applications. Information output filtering focuses on detecting extraneous content, preventing such extraneous content from being displayed, and then alerting monitoring tools that anomalous behavior has been discovered.
Organization-defined parameters
These values must be resolved through the organization’s tailoring and governance process. Bracketed parameter references in the control text identify where a decision is required.
From control text to operational evidence
Use Information Output Filtering as a testable risk decision. Translate the official statement into accountable people, repeatable processes, configured technology, and evidence that demonstrates the outcome over time. In this family, pay particular attention to flaw remediation, malicious-code protection, monitoring, integrity, and trustworthy information handling.
Implementation workflow
- Define the control boundary, responsible owner, inherited portions, and systems or processes in scope.
- Resolve each organization-defined parameter before declaring the control implemented.
- Document how the implementation satisfies every clause of the official control statement.
- Collect evidence as a normal byproduct of operation rather than only before an assessment.
- Review exceptions, changes, and monitoring results on a risk-based cadence.
Evidence examples
- patch and remediation records
- malware protection configuration
- monitoring alerts and response records
- integrity validation and exception reports
Common failure patterns
- patch compliance hides unsupported assets
- alerts generated without response ownership
- exceptions never expire
- integrity monitoring excludes critical configurations
Questions practitioners should ask
- What risk decision is this control intended to support in this system?
- Which parts are implemented locally, inherited, shared, or not applicable—and what evidence supports that decision?
- Do the documented narrative, deployed configuration, operating process, and collected evidence agree?
- What event or threshold requires the implementation to be reviewed or changed?
Assessment objectives and methods
Show the assessment objective
information output from [Organization-defined: software programs and/or applications] is validated to ensure that the information is consistent with the expected content.
Examine
- System and information integrity policy
- system and information integrity procedures
- procedures addressing information output filtering
- system design documentation
- system configuration settings and associated documentation
- system audit records
- system security plan
- other relevant documents or records
Interview
- Organizational personnel responsible for validating information output
- organizational personnel with information security responsibilities
- system/network administrators
- system developer
Test
- Organizational processes for validating information output
- automated mechanisms supporting and/or implementing information output validation
