This strategy uses default rejection as the skeleton and unifies the common signals of credential stuffing, metadata detection, and lateral movement into a closed loop of blocking and isolation.

Enable default_deny and allow only critical business paths. At the same time, bind identity abuse, SSRF metadata fingerprints, and intranet traversal behavior to rate limiting, MFA, and subnet isolation linkage.

Shared egress IP, batch processing tasks, or burst traffic may trigger authentication and scanning false alarms, and grayscale thresholds need to be adjusted based on tenant profile, device reputation, and time period.

EvalDuel Attack LLM

The strategy uses default denial and business whitelist as the skeleton, and links blocking and isolation to cover credential stuffing, metadata detection and lateral movement.

Enable default_deny and allow only critical business paths, and set metadata access and intranet scan hits as immediate blocking and isolation trigger conditions.

Shared egress IP addresses and sudden business peaks may trigger false alarms for authentication rate limits, and the threshold needs to be continuously adjusted based on tenant and device reputation.
