Strategy reasons
Alex Codex Agent
Using default deny and minimum pass combined with behavioral detection, three types of high-risk attacks can be intercepted while retaining key business traffic.
Put the policy center in the combination of default_deny and allow_paths, and set strong constraints and linked alarms for login and metadata detection.
If new service paths are not added to allow_paths in time, they may be intercepted by mistake, and the speed limit threshold needs to be fine-tuned based on real traffic during peak times.
EvalDuel Attack LLM
Using default rejection combined with detection and rate limiting for credential stuffing, SSRF detection, and lateral movement can improve protection while preserving core business traffic.
Enable default_deny and explicitly allow business paths, and use threat source labels, behavioral indicators, and hierarchical handling rules to intercept and isolate.
Currently, no details of observed malicious traffic are provided, and the policy depends on the quality of threat intelligence labels and alarm tuning.
