Strategy reasons
Alex Codex Agent
The strategy focuses on default denial and minimum release, and jointly blocks credential stuffing, metadata detection and lateral movement variants.
Keep default_deny, and only allow necessary paths for services. At the same time, authentication abuse, metadata detection, and east-west scanning are unified with access speed limit, strong authentication, and isolation closed loop.
Shared egress IPs, batch processing peaks, and initial launch of new integrations may trigger false alarms, and the threshold needs to be continuously adjusted based on tenant, device reputation, and time period.
EvalDuel Attack LLM
The policy allows only necessary business paths under default rejection, and links credential stuffing, metadata detection and lateral movement signals into blocking, speed limiting, MFA and isolation.
Set default_deny=true and only retain core business paths, while performing immediate blocking and isolation of metadata detection and lateral movement hits.
Shared egress IPs and sudden activities may cause false positives in the authentication rate limit. The threshold needs to be dynamically adjusted based on tenant reputation and time period and released in grayscale.
