Playbooks proactive · reactive · detective
Six playbooks structured from OWASP Agentic AI v1.1: 121 Helmwart action entries across 6 playbooks, mapped onto 66 Helmwart mitigations. Each playbook follows an OWASP Decision Path step and the source's Proactive, Reactive, and Detective organization; Helmwart adds implementation-specific actions and mappings.
Preventing AI Agent Reasoning Manipulation
Stop attackers from rewriting an agent’s plan or hiding its tracks.
Goal: Prevent attackers from manipulating AI intent, security bypasses through deceptive AI behaviours, and enhance AI actions traceability.
Preventing Memory Poisoning & AI Knowledge Corruption
Keep short- and long-term memory clean of adversarial writes and retrievals.
Goal: Prevent AI from storing, retrieving, or propagating manipulated data that could corrupt decision-making or spread misinformation.
Securing AI Tool Execution & Preventing Unauthorised Actions Across Supply Chains
Keep tool invocations on-policy and the upstream components trustworthy.
Goal: Prevent AI from executing unauthorised commands, misusing tools, or escalating privileges due to malicious manipulation, including across the agent’s supply chains.
Strengthening Authentication, Identity & Privilege Controls
Make every agent and tool prove what it is before doing anything privileged.
Goal: Prevent unauthorised AI privilege escalation, identity spoofing, and access control violations.
Protecting HITL & Preventing Decision Fatigue Exploits
Keep human oversight effective when the agent fan-out tries to swamp it.
Goal: Prevent attackers from overloading human decision-makers, manipulating AI intent, or bypassing security through deceptive AI behaviours.
Securing Multi-Agent Communication & Trust Mechanisms
Make every inter-agent message authenticated, integrity-checked, and bounded.
Goal: Prevent attackers from corrupting multi-agent communication, exploiting trust mechanisms, or manipulating decision-making in distributed AI environments.
Source basis: OWASP Agentic AI: Threats and Mitigations v1.1 (Dec 2025), §Mitigation Strategies. OWASP supplies the six playbooks, threat coverage, and step structure. Helmwart expands them with implementation-oriented actions and per-action mappings onto deployable controls.
