Mitigating Controls (NIST 800-53 r5) AI

prevent

Directly requires validation of all inputs to the VTS driver, blocking the malformed data that produces the arbitrary write.

prevent

Applies hardware or OS memory-protection mechanisms that can deny or contain the unauthorized memory write originating from the driver flaw.

prevent

Enforces process/kernel isolation boundaries so that an arbitrary write inside the VTS driver cannot freely corrupt other address spaces or security functions.

detects

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.

prevents

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.

prevents

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.

prevents

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.

prevents

Requiring language-specific secure coding standards, peer review, SAST and documented mitigation of common programming errors forces validation of all inputs before they are trusted.

none

Regular automated validation of system software and data content, combined with scanning of all inbound files, enforces input validation at the boundary before untrusted content is processed.
