Should security teams rely on framework tracing or kernel telemetry for AI agent detection?

Why This Matters for Security Teams

AI agents change the detection problem because execution is no longer limited to a human sitting at a keyboard. Agents can call tools, chain actions, retrieve data, and act through intermediate frameworks that may log their own version of events. That makes the choice of telemetry source a control decision, not just an observability preference. The NIST AI Risk Management Framework is useful here because it frames trustworthy AI operations around governance, traceability, and risk treatment rather than assuming any single log source is authoritative.

Framework tracing can still be useful, but it should be treated as application-generated evidence, not a trusted security boundary. If the agent runtime, orchestration layer, or prompt-handling code is compromised, traces can be incomplete, edited, delayed, or misleading. Kernel telemetry and control-plane signals are harder to fake because they sit closer to actual execution, file access, network activity, and process behavior. That is why detection strategy needs to assume partial deception at the application layer and corroborate with lower-level evidence. In practice, many security teams discover trace gaps only after an agent has already executed an unwanted tool call, rather than through intentional telemetry design.

How It Works in Practice

Operationally, the best pattern is layered collection. Kernel telemetry helps answer what actually ran, what it touched, and which child processes or network connections appeared. Control-plane logs help show who deployed the agent, what policies were loaded, which credentials were issued, and whether guardrails were bypassed. Framework tracing then adds semantic context: tool selection, prompt flow, retrieval decisions, and the chain of reasoning that led to an action. That combination is aligned with the attack patterns described in the MITRE ATLAS adversarial AI threat matrix and the OWASP Agentic AI Top 10, both of which emphasize that AI systems can be manipulated at multiple layers.

• Use kernel telemetry to detect process injection, suspicious child processes, unusual file writes, and outbound connections.
• Use control-plane logs to verify model version, policy state, secret issuance, and tool authorization.
• Use framework traces to reconstruct the decision path after an alert fires, not as the primary alert source.
• Correlate agent actions with identity and secret usage so that a tool call can be tied to a real execution context.

For teams building detections, this means placing high confidence on signals that are harder for the agent runtime itself to manipulate. Framework logs are still valuable for triage and root-cause analysis, especially when paired with NIST Cybersecurity Framework 2.0 control mapping and NIST SP 800-53 Rev. 5 Security and Privacy Controls for logging, monitoring, and accountability. These controls tend to break down when the agent runs in a highly abstracted serverless or managed runtime because visibility into process-level behavior and audit completeness is reduced.

Common Variations and Edge Cases

Tighter kernel and control-plane monitoring often increases engineering overhead, requiring organisations to balance detection depth against deployment complexity and data volume. In some environments, such as browser-based agents, managed SaaS copilots, or heavily sandboxed runtimes, kernel telemetry may be thin or unavailable. In those cases, current guidance suggests prioritising the strongest available lower-layer signals and compensating with immutable platform audit logs, egress controls, and strict tool authorization. There is no universal standard for this yet, especially across vendor-hosted agent stacks.

Framework tracing becomes more important when the question is not just whether an action occurred, but why the agent chose it. That is especially useful during incident response, policy tuning, and model evaluation. But if tracing is emitted by the same application tier that could be compromised, it should never be the sole detection source. This is one reason the CSA MAESTRO agentic AI threat modeling framework and Anthropic’s report on the first AI-orchestrated cyber espionage campaign are useful references: they reinforce that adversaries can manipulate the agent’s decision path as well as its output. Best practice is evolving, but the practical rule remains simple: detect on harder-to-fake telemetry, then investigate with traces.
