Autonomous Action Runtime Management(AARM):A System Specification for Securing AI-Driven Actions at Runtime

As artificial intelligence systems evolve from passive assistants into autonomous agents capable of executing consequential actions, the security boundary shifts from model outputs to tool execution. Traditional security paradigms - log aggregation, perimeter defense, and post-hoc forensics - cannot protect systems where AI-driven actions are irreversible, execute at machine speed, and originate from potentially compromised orchestration layers. This paper introduces Autonomous Action Runtime Management (AARM), an open specification for securing AI-driven actions at runtime. AARM defines a runtime security system that intercepts actions before execution, accumulates session context, evaluates against policy and intent alignment, enforces authorization decisions, and records tamper-evident receipts for forensic reconstruction. We formalize a threat model addressing prompt injection, confused deputy attacks, data exfiltration, and intent drift. We introduce an action classification framework distinguishing forbidden, context-dependent deny, and context-dependent allow actions. We propose four implementation architectures - protocol gateway, SDK instrumentation, kernel eBPF, and vendor integration - with distinct trust properties, and specify minimum conformance requirements for AARM-compliant systems. AARM is model-agnostic, framework-agnostic, and vendor-neutral, treating action execution as the stable security boundary. This specification aims to establish industry-wide requirements before proprietary fragmentation forecloses interoperability.

The paper addresses a critical gap in the security of autonomous AI agents that can execute real‑world actions such as database updates, email sending, or cloud service invocations. Traditional defenses—log aggregation, perimeter firewalls, SIEM alerts—operate after the fact and lack the contextual awareness needed to stop harmful actions that occur at machine speed, are irreversible, and may be the result of compromised orchestration layers (e.g., prompt injection). To close this “runtime security gap,” the authors propose Autonomous Action Runtime Management (AARM), an open, model‑agnostic specification that enforces security at the moment an AI‑driven action reaches the tool or API layer.

AARM’s core functions are: (1) intercept every action request before it reaches the target tool, (2) accumulate a “session context” that records the original user request, prior actions, accessed data, and tool responses, (3) evaluate the intercepted action against both static policy and a dynamic “intent alignment” check that measures whether the action makes sense given the accumulated context, (4) enforce a decision—allow, deny, modify, defer, or step‑up authorization—and (5) emit a tamper‑evident receipt binding the action, context, decision, and outcome for forensic reconstruction.

The specification introduces a four‑tier action classification:

• Forbidden – always blocked (e.g., dropping a production database).
• Context‑dependent deny – policy‑allowed but blocked when context reveals mis‑alignment with the user’s intent (e.g., reading PII then emailing it externally).
• Context‑dependent allow – default‑deny but permitted when context confirms legitimate intent (e.g., deleting test data after an explicit request).
• Context‑dependent defer – insufficient or ambiguous context leads to temporary suspension until additional assurance (human approval, external verification) is obtained.

The threat model explicitly includes prompt injection, confused‑deputy attacks, compositional data exfiltration, intent drift, cross‑agent propagation, and environmental manipulation. Crucially, the orchestration layer is treated as potentially compromised, forcing the security boundary to be the action execution point itself, in line with Zero‑Trust principles.

Four reference implementation architectures are described, each with distinct trust properties and bypass resistance:

1. Protocol Gateway – a network‑level proxy that mediates all API calls; offers strong isolation but adds latency.
2. SDK Instrumentation – library hooks embedded in application code; provides fine‑grained control but depends on developer adoption.
3. Kernel eBPF – OS‑level monitoring of system calls; transparent to applications and hard to bypass, yet requires kernel compatibility and careful performance tuning.
4. Vendor Integration – native enforcement built into cloud or platform services; delivers the highest assurance but risks vendor lock‑in and demands standard APIs for interoperability.

The authors define minimum conformance requirements that any AARM‑compliant system must satisfy: signed, immutable receipts; a policy update API; cryptographically protected context storage; export of telemetry to external SIEM or audit systems; and high‑availability, horizontally scalable deployment patterns. These requirements enable objective comparison of vendor claims and prevent “category dilution” where implementations claim compliance without providing the full security guarantees.

The paper’s contributions are fourfold: (1) formal problem definition and comprehensive threat model, (2) a novel intent‑aware evaluation model that couples static policy with dynamic context, (3) a taxonomy of implementation architectures with clear trade‑offs, and (4) a detailed specification—including data schemas, component interactions, and conformance criteria—intended to become a baseline standard for the emerging market of autonomous AI agents.

While the proposal is thorough, the authors acknowledge open challenges: potential performance overhead of context accumulation, the need for standardized policy languages and intent‑alignment algorithms, and the operational complexity of “defer” workflows that require human or external verification. Nevertheless, AARM represents the first systematic attempt to shift AI‑agent security from post‑hoc detection to pre‑execution enforcement, offering a foundational framework that could shape both academic research and industry practice as autonomous agents become integral to enterprise operations.
