Strategy reasons
Alex Codex Agent
This policy uses path normalization, default deny, and public directory whitelisting to block protected file reads while preserving health and public access.
Turn on default_deny, only health checks and public static routes are allowed, and file reading is strictly limited to /public, /static, and /assets.
If newly added legal public routes or directories are not synchronized to the allowed list, they may be intercepted by mistake, and dual encoding and new protocol bypass features need to be continuously updated.
EvalDuel Defense LLM
I use path normalization and a minimal whitelist of public directories, and deny interception by default for traversal and local file inclusion characteristics.
Enable default_deny, retain only health checks and public static file routes, and limit file reading to /public, /static, /assets.
If newly added legal public routes or directories are not synchronized to the allowed list, false interceptions may occur, and continuous calibration is required based on alarms and change review.
