Mitigating Controls
Mitigating Controls (NIST 800-53 r5) AI
AC-3 enforces file-system access authorizations so that temporary files cannot be read or modified by unauthorized processes.
AC-6 reduces the privileges available to processes that create or access temporary files, limiting blast radius if a file is predictable or left readable.
SC-4 directly stops unauthorized information leakage through shared resources such as world-writable temporary directories.

Secure SDLC practices directly require avoiding insecure temp-file creation patterns.

Security testing can detect insecure temporary files but does not prevent their creation.
Secure development life cycle mandates secure handling of temporary files during design and coding.
Application security requirements can specify secure temporary-file creation and access controls.
Secure system architecture principles discourage insecure temporary-file patterns but do not directly address them.
Secure coding standards explicitly require safe temporary-file APIs and permissions.
Information deletion policies may cover secure removal of temporary files after use.
