Strategy reasons
Alex Codex Agent
The policy is centered on default denial and minimum release, and directly links credential abuse, metadata detection and lateral movement signals to automatic containment.
Keep default_deny=true, allow only business critical paths, and enable hierarchical rate limiting, MFA, and isolation processing for three types of attacks.
If new business paths are not added to allow_paths in time or the threshold is not calibrated with traffic changes, false interceptions or short-term false negatives may still occur.
EvalDuel Defense LLM
The policy is centered around deny-by-default and minimum release, and implements coordinated containment of credential abuse, metadata detection, and lateral movement.
Enable default_deny and allow only necessary business paths. At the same time, directly bind the three types of attack indicators to blocking, speed limiting, MFA and isolation actions.
If allow_paths and thresholds are not updated in a timely manner for new service paths or changes in traffic patterns, false interceptions or short-term missed reports may occur.
