PR.PS-06 mostly match
prevents

Secure SDLC practices directly include code analysis, input validation, and testing that prevent divide-by-zero errors.

ID.RA-01 partial match
prevents

Vulnerability identification processes can discover divide-by-zero flaws via static analysis or testing.

PR.PS-02 partial match
prevents

Routine patching and replacement can remediate divide-by-zero bugs present in deployed software.

detects

Security testing in development can detect divide-by-zero conditions before release.

prevents

Secure development lifecycle includes input validation and error-handling practices that can prevent divide-by-zero faults.

prevents

Application security requirements can mandate checks for zero denominators and safe arithmetic handling.

prevents

Secure architecture principles encourage defensive coding patterns that avoid arithmetic exceptions.

prevents

Secure coding standards directly require validation to prevent divide-by-zero and similar runtime faults.
