Mitigating Controls (NIST 800-53 r5) AI
Requires integrity verification tools that detect unauthorized changes when checksum validation is missing or flawed.
Developer testing and evaluation can discover missing input validation through analysis or test cases.
Mandates cryptographic mechanisms that include integrity protection, preventing improper checksum validation.
Requires protection of transmitted information integrity, directly mandating correct validation of integrity checks.
SI-10 directly requires validity checks on information inputs, structurally preventing improper or missing validation.
Requiring documented development standards and tools can embed input-validation practices into the engineering process.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Requires cryptographic hashes and signatures that directly enforce integrity-check validation for data at rest.
Requires cryptographic hashes and signatures that directly enforce integrity-check validation for data in transit.
Secure SDLC practices directly require and enforce input validation during development.
Mandates pre-acquisition integrity assessment, addressing only the initial portion of the weakness lifecycle.
Requires verification of backup integrity, covering validation only within recovery scenarios.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Cryptographic controls mandate integrity mechanisms whose correct validation directly prevents CWE-354.
Secure coding standards require proper implementation and validation of checksums or MACs.
Testing against a defined set of requirements and using code review plus vulnerability scanning forces validation of inputs and handling of unanticipated conditions, reducing the chance that malformed data will be accepted.
Secure-coding guidelines and mandatory security testing (including code scans) compel developers to validate and sanitize inputs at design and implementation time, lowering the incidence of malformed or malicious data reaching downstream components.
Mandating input controls that include integrity checks and input validation ensures that untrusted data is examined before use, blocking the root cause of many injection and malformed-data weaknesses.
Security-by-design principles explicitly call for data validation and sanitization at every layer, reducing the chance that malformed or malicious input will be processed without scrutiny.
