Mitigating Controls (NIST 800-53 r5) AI

Baseline configuration directly requires documenting and maintaining secure initial settings instead of insecure defaults.

Configuration settings mandate the most restrictive values be applied at initialization, eliminating reliance on insecure factory defaults.

Malicious-code protection at entry points blocks dangerous file types from being accepted and executed.

Least privilege reduces the blast radius of any insecure default permissions that remain after initialization.

Least functionality restricts the file types and automatic processing capabilities the system will accept.

Security engineering principles include explicit requirements for secure defaults during resource initialization and design.

Secure development practices include designing products with secure defaults rather than insecure ones.

finds

Configuration and acceptance testing verify that file-upload handling enforces allowed types and does not permit dangerous content to be stored or executed.

prevents

Mandating secure baseline templates and immediate replacement of vendor defaults directly stops systems from being deployed with insecure factory settings that attackers can exploit.

prevents

Secure-coding guidelines and security testing explicitly address restrictions on allowed file types and upload handling, reducing the risk that dangerous file uploads are accepted without validation.

prevents

Mandated testing for malicious content and known vulnerabilities reduces the likelihood that an outsourced component will contain or accept dangerous file types that could later be uploaded or executed.

prevents

Requiring documented specification, testing, and acceptance of changes ensures that new or modified components are not initialized with insecure default settings that would otherwise be left in production.

mitigates

Application allow-listing and pre-use scanning of received files directly blocks the introduction of executable content that has not been vetted, eliminating the primary vector for unrestricted dangerous file uploads.
