Large Language Model (LLM)-driven Secure Shell (SSH) honeypots have rapidly displaced static, templated decoys, yet they share a structural limitation: a single model and a single policy serve every turn of an intrusion, from low-stakes reconnaissance to high-value persistence. This review asks whether honeypots can instead adapt their inference to the attacker’s phase. We conduct a Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020-guided systematic mapping review of fifty influential studies (2020–2026) drawn from three strands—honeypots and generative deception, cost-aware model routing and mixture-of-experts inference, and LLM agents, embeddings, and retrieval-augmented generation in security operations—assembled under a disclosed, purposive top-50 prioritization ranked by age-normalized citation velocity. That prioritization is a deliberate mapping strategy: it surfaces the field’s most influential work rather than claiming exhaustive coverage, and a sensitivity analysis tests how robust the conclusions are to the cap. Three findings emerge. Across the reviewed literature, honeypot adaptivity has advanced at the policy and generation layers but not at the inference-allocation layer; the routing literature has solved capacity allocation but conditions only on query-intrinsic signals, not on adversarial session phase; and embedding-based analytics, corroborated by a production deployment, show the phase signal is observable and reliable. The strands are individually mature and mutually disconnected. We formalize this gap and propose a phase-adaptive, agent-oriented framework that pairs an embedding-based phase estimator and an O(1) phase-to-model dispatch layer with an unprivileged, campaign-level observation substrate.The review contributes a reproducible corpus, an age-normalized bibliometric ranking, a formal gap analysis, and a conceptual architecture that operationalizes the maturation arc from static to phase-adaptive honeypots.
Large language model (LLM) backends increasingly generate SSH-honeypot output, yet the literature fixes one backend per system and judges realism by human evaluators, never asking which LLM is fit to play the shell or measuring the catastrophic failure of a backend leaking its own instructions. We fix one hardened unprivileged user scaffold and prompt, vary only the backend across eleven LLMs, and replace the human judge with an objective, prompt-anchored leakage metric. Across a controlled 42-command battery (20 trials each; 8736 responses) and a live adaptive corpus (8626 responses), we score six dimensions: instruction leakage, fidelity, hallucination, latency, verbosity, and stability. Exactly one backend (gemma-4-31b-it) reproduces verbatim leakage in both datasets and is disqualified; the other ten never leak. A deterministic handler layer serves 33 of 42 commands identically across backends, confining model risk to nine generative commands, where flag fabrication ranges 0–95%, latency spans an order of magnitude, and a held-out classifier identifies the backend from one response at 71% versus 9% chance, a fingerprinting risk. We report a per-dimension scorecard rather than a weight-sensitive ranking. Honeypot safety on the privilege boundary is a property of the architecture; realism, speed, cost, and one catastrophic leak are properties of the model.
