Reasoning / Planning Paradigm (KC3)

Security implications

Reasoning processes can propagate hallucinations, be manipulated to achieve unauthorized goals, exhibit misaligned behaviors, create untraceable decision trails, or craft manipulative responses.

Implementation considerations

Security requires verification at key decision points, traceability of reasoning chains, validation of intermediate conclusions, and checks for logic consistency and alignment with intended goals.

Sub-components

• KC3.1 Structured Planning / Execution

  Focuses on decomposing tasks into a formal plan, defining sequences of actions (often involving tool calls), and executing the plan, sometimes with separate planner/executor components (e.g., ReWoo, LLM Compiler, Plan-and-Execute).

• KC3.2 ReAct (Reason + Act)

  Dynamically interleaves reasoning steps with actions (like using tools or querying APIs) and updates reasoning based on feedback.

• KC3.3 Chain of Thought (CoT)

  Enhances reasoning quality by prompting step-by-step "thinking," inducing an LLM to generate a set of "thoughts" before arriving at a final action or conclusion.

• KC3.4 Tree of Thoughts (ToT)

  Generalizes CoT by exploring multiple reasoning paths and plans in parallel with lookahead, backtracking, and self-evaluation.

Threats

• T5 Cascading Hallucination Attacks

  Foundation models generate incorrect information that propagates through the system, affecting reasoning quality and being stored in memory across sessions or agents.

• T6 Intent Breaking & Goal Manipulation

  Attacks that manipulate the agent's core decision-making to achieve unauthorized goals, breaking control flow, abusing shared context, or interfering with isolated data.

• T7 Misaligned & Deceptive Behaviors

  Model alignment issues leading to unintended behaviors that impact users, organizations, or broader populations through subtle reasoning or tool usage misalignments.

• T8 Repudiation & Untraceability

  Making agent actions difficult to trace through workflow manipulation, obscuring decision trails in reasoning chains, or tampering with evidence in memory.

• T15 Human Manipulation

  Models exploit human trust to manipulate users, leveraging reasoning capabilities or operational access to influence human decisions.

Controls

• M18 Incident Response & Recovery Framework: Implement comprehensive incident response capabilities specifically designed for agentic AI systems, including automated containment, forensic analysis, recovery procedures, and lessons learned integration to rapidly respond to security incidents and minimize impact.

Architecture patterns

• Sequential Agent Architecture: A straightforward linear workflow where a single agent processes tasks through a linear workflow.
• Hierarchical Agent Architecture: This architecture introduces a KC2.2 (Hierarchical planning) model where a central orchestrator agent decomposes complex tasks and delegates them to specialized sub-agents.
• Collaborative Agent Swarm: A collaborative swarm is a decentralized system where multiple peer agents operate without a strict hierarchy, using KC2.3 (Multi-agent collaboration).
• Reactive Agent Architecture: Agents designed for responsive workflows, often event-driven, where actions are taken based on immediate inputs or changes in the environment.
• Knowledge-Intensive Agent Architecture: Agents focused on leveraging and processing large volumes of external data, typically using sophisticated RAG approaches.
