用元认知框架让AI安全系统更懂自己，应对混乱信息做出可靠决策。

Cybersecurity decision-making increasingly occurs in environments characterized by uncertainty, partial observability, and adversarial manipulation, where heterogeneous signals from multiple sources are often incomplete, ambiguous, or conflicting. Traditional Security Orchestration, Automation, and Response (SOAR) systems rely on deterministic pipelines and threshold-based triggers, limiting their ability to support reliable decision-making under such conditions. This paper proposes a probabilistic, agentic framework for cybersecurity orchestration that models decision-making as a meta-cognitive process. The framework decomposes cybersecurity functions into interacting agents responsible for detection, hypothesis formation, contextualization, explanation, and governance, coordinated through a meta-cognitive judgement mechanism. This mechanism evaluates uncertainty, agent disagreement, and operational constraints to determine decision readiness, enabling adaptive strategies including automated action, escalation, deferral, and evidence refinement. Empirical evaluation on benchmark datasets (CICIDS2017 and NSL-KDD), augmented with adversarial and uncertain conditions, demonstrates that the proposed approach improves robustness and decision quality compared to deterministic and single-agent baselines. The framework achieves higher accuracy under noise, reduces false positive rates, and produces better-calibrated confidence estimates, while enabling more adaptive and context-aware decision behavior. By explicitly modeling meta-cognitive processes - monitoring, evaluation, control, and reflection - the proposed approach reframes cybersecurity as an instance of AI-mediated cognitive problem solving, supporting accountable autonomy and more effective human-AI collaboration in adversarial environments.
