Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation of inputs to system processes, which is the exact flaw (CWE-20) that allowed an unprivileged process to terminate a root process.
Enforces least privilege so that unprivileged processes cannot hold or exercise the rights needed to terminate root-owned processes.
Access enforcement mechanisms must mediate all subject-object operations, preventing unauthorized termination of privileged processes by untrusted callers.

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.
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.
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.
