PR.PS-06 mostly match
prevents

Secure SDLC practices directly prevent external format strings via code review, static analysis, and safe APIs.

ID.RA-01 partial match
prevents

Vulnerability identification can discover existing format-string flaws but does not prevent their introduction.

finds

Security testing in development can detect format-string vulnerabilities before release.

prevents

Secure SDLC mandates input validation and safe API usage that can prevent externally-controlled format strings.

prevents

Application security requirements can specify safe formatting functions and ban uncontrolled format strings.

prevents

Secure architecture principles discourage dangerous string-handling patterns that lead to format-string issues.

prevents

Secure coding standards directly forbid the use of untrusted format strings and prescribe safe alternatives.
