Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

AC-6 limits privileges granted to processes creating or accessing temporary files, reducing blast radius of insecure permissions.

SC-4 directly stops unauthorized information transfer through shared resources such as temporary files created with weak permissions.

AC-3 enforces access authorizations on system resources including files, structurally stopping insecure temporary file permissions from being exploitable.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require proper temporary-file creation and permission handling.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

Secure coding standards directly prohibit insecure temporary file creation and permissions.

finds

Security testing can detect insecure temporary files but does not prevent their creation.

prevents

Secure SDLC mandates secure handling of temporary files and permissions.

prevents

Application security requirements include secure creation and permissioning of temporary files.

prevents

Secure architecture principles require least-privilege file creation and access controls.

prevents

Information access restriction can limit exposure but does not address file creation itself.
