finds

Security testing in development can detect path-traversal flaws before release.

prevents

Secure SDLC mandates input validation and path-handling controls that directly mitigate path traversal.

prevents

Application security requirements include rules for safe file-path construction and canonicalization.

prevents

Secure architecture principles require proper directory restrictions and input sanitization to prevent traversal.

prevents

Secure coding standards explicitly forbid unsafe path concatenation and mandate canonicalization routines.

mitigates

Information access restriction limits file reachability but does not address the input-validation flaw itself.
