Explicitly requires removing confidential data from process memory when no longer needed, directly addressing dead-store removal of buffer clears.

Secure SDLC practices include compiler-aware mitigations (volatile, memset_s) that prevent this exact weakness.

Security testing can detect residual sensitive data left by dead-store removal, but does not prevent the weakness itself.
