Strategy reasons
Alex Codex Agent
This strategy is based on default denial and hierarchical linkage processing, intercepting three types of attack variants while keeping key business paths available.
Set immediate blocking of metadata detection, abnormal login rate limit, and isolation triggered by lateral movement as three main lines of defense, and use explicit allow_paths to ensure business continuity.
If the peak period threshold is not calibrated according to the real traffic or new service paths are not added to allow_paths in time, false interception or alarm noise may occur.
EvalDuel Attack LLM
The policy is based on default denial and explicit business release, and establishes linked blocking and isolation for credential collision, metadata detection and lateral movement.
Bind the disposal threshold to the observable attack signal, and once triggered, block the source, invalidate the session, and isolate the network segment simultaneously.
If there is legitimate automated access to metadata or a sudden increase in business peak logins, the exemption needs to be quickly adjusted based on the asset tag whitelist and traffic baseline.
