A Security Analysis of Long-Horizon Agentic AI Systems: Threats, Evaluation, and Framework Development

arXiv:2606.14816v1 Announce Type: cross Abstract: This paper presents a structured analysis of security challenges in long-horizon agentic AI systems. The study reviews existing threats, evaluation approaches, attack propagation mechanisms, and security frameworks. A taxonomy of security threats and a framework for analyzing attack propagation are proposed to support future research in agentic AI security

Why this matters
Why now

The rapid advancement and deployment of agentic AI systems necessitate concurrent development in security frameworks to address emergent vulnerabilities before widespread adoption. The paper's publication dates to 2026, indicating forward-looking research on a relevant and developing topic.

Why it’s important

A structured security analysis of long-horizon agentic AI systems is crucial for ensuring their safe and responsible development, preventing catastrophic failures, and building public trust. This research provides foundational knowledge for addressing critical risks associated with increasingly autonomous AI.

What changes

The focus on threat taxonomies and attack propagation mechanisms for agentic AI shifts the approach from reactive vulnerability patching to proactive security by design. This will lead to more robust, albeit potentially slower, development of AI agents.
