Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation of all inputs to the router management interface, blocking the malformed data that enables unauthorized software/functionality changes.
Mandates integrity verification of firmware and configuration files before and after any administrative action, detecting or blocking the unauthorized modifications introduced via the input flaw.
Enforces explicit access restrictions and authorization checks on all configuration-change operations, limiting the ability of even authenticated local admins to alter router software outside approved mechanisms.

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.
