Strategy reasons
Alex Codex Agent
codex-llm
confidence 0.95
This policy uses default deny, path normalization, and public directory whitelisting to block protected file reads while preserving state and public file access.
Use default_deny and strictly limit file reading to the normalized `/public` and `/assets` root directories.
If legal downloads or file routing are subsequently added, they must be explicitly added to the allow list and the detection rules must be synchronized according to the principle of least privilege.
EvalDuel Attack LLM
codex-llm
confidence 0.95
Use path normalization and least-privilege whitelisting to block sensitive file reads while preserving health checks and exposing static access.
Enable default_deny and only allow files to be read from the normalized /public and /static root directories.
If legitimate business routes or file root directories are subsequently added, they must be added to the whitelist one by one with minimum permissions and the interception characteristics must be updated simultaneously.
