Evidence

推荐处置 recommendation

  • uploaded_file=mixed_scenario_features.csv
  • input_label=unknown_suspicious
  • uploaded feature row evaluated by EncGuard scenario rule engine
  • anomaly_score=90.106726
  • anomaly_risk_score=90.0
  • uncertainty_gate=0.16878
  • safe_lab_batch=safe-lab-20260704092453-e82171
  • scenario=unknown_suspicious_like
  • ground_truth_label=unknown_suspicious
  • safe synthetic metadata only; no payload and no real attack execution

recommendation：Review uploaded feature context and validate whether this communication is authorized.

Attack Chain

攻击链关联 attack_chain

暂无攻击链关联。

Safety Boundary

安全边界说明

  • EncGuard 不解密 SSH/TLS/HTTPS/SFTP/SCP payload。
  • 当前检测依据为连接元数据、流量统计、规则 evidence、模型预测、异常检测和攻击链聚合。
  • post_bruteforce_action、encrypted_tunnel、data_exfiltration 主要由规则、攻击链或异常检测补强。
