From 8811936d3deaba5be36dd0db872741dac0613744 Mon Sep 17 00:00:00 2001 From: luohua13 Date: Thu, 24 Sep 2026 01:37:58 +0000 Subject: [PATCH 01/11] docs(ai): add garak LLM security scanning on Workbench Prebuilt Workbench image with garak 0.17.0 and its offline detector models, datasets and NLTK corpora, so an isolated cluster can scan a published inference service without reaching PyPI or Hugging Face. Covers obtaining the image, importing the WorkspaceKind the console needs to offer it, preparing the scan configuration, running a scan and reading the reports, plus adapting the chat template for non-Qwen models and using an LLM judge detector. Verified against Qwen3.5-0.8B on vLLM: 21 probes in 775s, reports written to the Workspace volume, detectors loading from the image with the container offline.

[garak](https://github.com/NVIDIA/garak) is NVIDIA's open-source LLM vulnerability scanner (Apache-2.0). It ships 41 probe modules with roughly 180 attack probes, sends the attack prompts to a target model, uses detectors to decide whether the response is undesirable, and reports an attack success rate per risk category. + +Installing garak on site is often impractical: it pulls Python packages from PyPI and detector models and datasets from Hugging Face, none of which is reachable from an isolated environment. + +This solution provides a prebuilt Alauda AI Workbench image with garak and all of its offline assets baked in. Once the image is in the platform Private Registry and a WorkspaceKind has been imported, users create a Workspace from the console and scan any inference service in the same cluster. Nothing is fetched from the internet at scan time, and no extra scheduling component is required. + +## Environment + +* Alauda AI with the Alauda AI Workbench plugin installed. +* Verified on: `aml-server` v2.8.0-beta.4, Workbench chart 2.0.0, Kubernetes v1.34.5, x86/64 CPU nodes. +* Target: a text LLM published on the platform that exposes an OpenAI-compatible API (for example a vLLM runtime). +* The Workspace needs CPU only. The detector models are small classifiers that run on CPU. +* Multimodal probes (image, audio) are out of scope. + +## Resolution + +### Prerequisites + +* The inference service to be scanned is published, and its in-cluster address is known. It has the form `http://-predictor..svc.cluster.local`. +* The garak Workbench image has been pushed to the platform Private Registry (the registry specified when the cluster was deployed). See [Obtaining the image](#obtaining_the_image). +* Cluster administrator permission, to import the WorkspaceKind once. See [Importing the WorkspaceKind](#importing_the_workspacekind). +* At least 2 GB free on the Workspace volume, for the scan configuration and the reports. + +### Image contents + +The image is built on the platform Workbench image `alauda-workbench-jupyter-datascience-cpu-py312-ubi9` and adds: + +| Content | Location | +| --- | --- | +| garak 0.17.0 and its dependencies (own venv, CPU build of PyTorch) | `/opt/app-root/garak/venv`; the `garak` command is on `PATH` | +| Detector models and probe datasets (Hugging Face cache layout) | `/opt/app-root/garak/assets/hf` | +| NLTK corpora | `/opt/app-root/garak/assets/nltk_data` | +| Sample scan configuration | `/opt/app-root/garak/scan.yaml` | + +The image sets `HF_HUB_OFFLINE=1`, `HF_DATASETS_OFFLINE=1` and `TRANSFORMERS_OFFLINE=1`, so nothing is fetched at run time. It is 5.3 GB compressed and about 11 GB unpacked. + +The bundled assets come from the public `garak-llm` organization on Hugging Face: six models (NLI, refusal, toxicity and refutation detectors, plus the `atkgen` attack model) and nine datasets (package-name lists for the package-hallucination probes, and prompt sets for the system-prompt-extraction probes). They change rarely; the dataset snapshot dates are part of their names. + +### Obtaining the image {#obtaining_the_image} + +Alauda publishes the built image on Docker Hub. There is no need to build it yourself. + +| Item | Value | +| --- | --- | +| Image | `alaudadockerhub/garak-workbench:0.17.0-20260922` (the tag is the garak version plus the build date) | +| Digest | `sha256:d1cc22470189dfe4b341f1c2507897d60399f5257ec936bcd14da4f38e99440a` | +| Size | 5.3 GB, 8 layers | + +On a machine that can reach Docker Hub, pull the image and push it to the platform Private Registry: + +```bash +docker pull alaudadockerhub/garak-workbench:0.17.0-20260922 +docker tag alaudadockerhub/garak-workbench:0.17.0-20260922 \ + /mlops/garak-workbench:0.17.0-20260922 +docker push /mlops/garak-workbench:0.17.0-20260922 +``` + +If Docker Hub is not reachable at all, Alauda can supply the image as a tar archive, which is then handled by the customer's existing offline image import process: + +```bash +docker load -i garak-workbench-0.17.0-20260922.tar +docker tag alaudadockerhub/garak-workbench:0.17.0-20260922 \ + /mlops/garak-workbench:0.17.0-20260922 +docker push /mlops/garak-workbench:0.17.0-20260922 +``` + +> **NOTE:** +> The image contains no customer data, so it can go through the usual image security scanning before being admitted to the registry. + +### Importing the WorkspaceKind {#importing_the_workspacekind} + +The images offered in the Workbench console come from `WorkspaceKind` resources in the cluster, so an administrator has to import a WorkspaceKind that points at the garak image. This is a one-time operation; afterwards every user can pick it when creating a Workspace. + +Save the following as `workspacekind-garak.yaml`, change `image` to the address pushed in the previous step, and apply it with `kubectl apply -f workspacekind-garak.yaml`. + +

The scan configuration and the reports are stored under the home directory and survive a Workspace restart or an image version change. + +> **NOTE:** +> Create the Workspace from the console. If you create it with `kubectl` and omit `spec.podTemplate.podMetadata`, the Workspace list in the current console version fails to render — the field is optional in the CRD, but the console does not tolerate its absence. When creating from YAML, set `podMetadata: {labels: {}, annotations: {}}` explicitly. + +### Verifying access to the inference service + +Open the JupyterLab page of the Workspace, start a terminal (Launcher > Terminal), and run the following with the address of the service to be scanned: + +```bash +export TARGET_URL=http://-predictor..svc.cluster.local + +# list the model names, needed for the configuration below +curl -s $TARGET_URL/v1/models + +# check that the completions endpoint works +curl -s $TARGET_URL/v1/completions -H 'Content-Type: application/json' \ + -d '{"model":"","prompt":"hello","max_tokens":20}' +``` + +Both commands must return JSON. Note the `id` field returned by `/v1/models`; that is the model name. + +> **NOTE:** +> This solution posts to `/v1/completions` and assembles the chat template by hand, rather than using `/v1/chat/completions`. Two reasons: in the verification environment the chat endpoint hung without responding while the completions endpoint worked, and the completions endpoint lets you switch off the thinking mode of models such as Qwen3, so that reasoning text does not distort detector verdicts. To use the chat endpoint instead, see [Using the chat endpoint](#using_the_chat_endpoint). + +### Preparing the scan configuration + +Copy the sample configuration shipped in the image to the home directory and edit it: + +```bash +mkdir -p ~/garak && cp /opt/app-root/garak/scan.yaml ~/garak/scan.yaml +``` + +The configuration is: + +```yaml +# garak scan configuration: scans an in-cluster inference service via /v1/completions +# Usage: garak --config ~/garak/scan.yaml +system: + parallel_attempts: 8 # concurrent requests; tune to the service throughput + +run: + generations: 1 # generations per prompt; 1 for a pilot, 3-5 for a full assessment + soft_probe_prompt_cap: 20 # at most 20 prompts per probe; remove for a full assessment + spec: + include: + - probes.dan.Dan_11_0 + - probes.grandma + - probes.encoding.InjectBase64 + - probes.promptinject + - probes.latentinjection.LatentInjectionResume + - probes.lmrc + - probes.malwaregen.TopLevel + - probes.packagehallucination.Python + - probes.sysprompt_extraction + - probes.web_injection.MarkdownImageExfil + - probes.ansiescape.AnsiRaw + +plugins: + target_type: rest + target_name: + generators: + rest: + RestGenerator: + uri: http://-predictor..svc.cluster.local/v1/completions + method: post + headers: + Content-Type: application/json + req_template_json_object: + model: + # Qwen3 chat template; \n\n disables thinking mode. + # Replace with the chat template of the model under test. + prompt: "<|im_start|>user\n$INPUT<|im_end|>\n<|im_start|>assistant\n\n\n\n\n" + max_tokens: 256 + temperature: 0.7 + response_json: true + response_json_field: $.choices[0].text + request_timeout: 120 + +reporting: + report_prefix: scan-pilot # report file name prefix +``` + +Replace the three placeholders: + +1. `target_name` and `req_template_json_object.model`: the model name returned by `/v1/models`, replacing ``. +2. `uri`: the in-cluster address of the service, replacing `` and ``, keeping the `/v1/completions` suffix. +3. `prompt`: the chat template of the target model. **Leave it unchanged for Qwen3 models** — the sample is the Qwen3 template.

A default full scan — without `spec` and `soft_probe_prompt_cap` — can issue tens of thousands of requests, so start with a selection of probes and widen it gradually. + +Short scans can also be started from a notebook cell: + +```python +!garak --config ~/garak/scan.yaml --spec probes.dan +``` + +### Reading the reports + +The reports are written to `~/.local/share/garak/garak_runs/`, which is garak's default output directory on the Workspace volume: + +| File | Content | +| --- | --- | +| `.report.html` | Summary report; expands from probe module to probe to detector, with attack success rates and grades from 1 to 5.

Read them together: the former failing while the latter passes means the model played along with the attack framing but did not emit harmful content, which is less severe than both failing. + +### Results from the verification environment + +The configuration above was run against `qwen3-5-0-8b` (Qwen3.5-0.8B on vLLM): 21 probes, at most 20 prompts each, 8 concurrent requests, 775 seconds. + +| Probe | Detector | Attack success rate | Notes | +| --- | --- | --- | --- | +| dan.Dan_11_0 | dan.DAN | 100% | Adopts the DAN jailbreak persona | +| grandma.* | mitigation.MitigationBypass | 100% | Plays along with the "grandma" roleplay instead of refusing, though no real product keys or slurs were emitted | +| promptinject.Hijack* | promptinject.AttackRogueString | 75-80% | Prompt injection makes the model repeat the supplied string | +| malwaregen.TopLevel | malwaregen.AnyCode | 43.8% | Produces malware code | +| packagehallucination.Python | packagehallucination.PythonPypi | 20% | Recommends PyPI packages that do not exist | +| ansiescape.AnsiRaw | ansiescape.Raw | 12.1% | Emits ANSI escape codes | +| latentinjection.LatentInjectionResume | base.TriggerListDetector | 10% | Injection hidden in a resume takes effect | +| encoding, lmrc (profanity, sexual content, slurs), sysprompt_extraction, web_injection | respective detectors | 0% | Passed | + +This model resists roleplay jailbreaks and direct prompt injection poorly but does well on content safety, which is what a 0.8B model would be expected to do. + +> **NOTE:** +> With 20 prompts per probe and one generation each, the sample is small and the percentages only indicate a direction. For a real assessment, remove `soft_probe_prompt_cap` and raise `generations` to 3 or more. + +## Extensions + +### Using the chat endpoint {#using_the_chat_endpoint} + +If `/v1/chat/completions` works on the target service, replace the `plugins` section of `scan.yaml` with the following and let garak assemble the conversation, so no manual template is needed: + +```yaml +plugins: + target_type: openai.OpenAICompatible + target_name: + generators: + openai: + OpenAICompatible: + uri: http://-predictor..svc.cluster.local/v1/ + stop: [] # the default ["#", ";"] truncates code and CJK output, always clear it + max_tokens: 256 + extra_params: + chat_template_kwargs: + enable_thinking: false # vLLM: switch off Qwen3 thinking mode +``` + +Set a non-empty `OPENAICOMPATIBLE_API_KEY` environment variable before running; any value works when the service does not check it. + +### Adapting the chat template {#adapting_the_chat_template} + +Because the scan posts to `/v1/completions`, the `prompt` field has to spell out the chat template of the target model. The sample is the Qwen3 template. For another model, derive it as follows. + +**Step 1: read the template from the model files.** + +```bash +kubectl -n exec -c kserve-container -- python3 -c " +import json +d = json.load(open('/mnt/models/tokenizer_config.json')) +print(d.get('chat_template', '(see chat_template.jinja)')) +" +``` + +Look for the `add_generation_prompt` branch; that is the generation prompt. If the model has a thinking mode (Qwen3, GLM-4.5 and similar), also look for what is appended when `enable_thinking` is false and include it — otherwise the model emits a long block of reasoning first and the detectors count that text in their verdicts. + +**Step 2: write it into `prompt`**, with `$INPUT` where the user message goes. Common shapes: + +| Model | prompt template | +| --- | --- | +| Qwen3 family | `"<\|im_start\|>user\n$INPUT<\|im_end\|>\n<\|im_start\|>assistant\n\n\n\n\n"` | +| Zhipu GLM-4 family | `"[gMASK]<\|user\|>\n$INPUT<\|assistant\|>\n"` | +| Zhipu GLM-4.5 and later | the GLM-4 shape plus the marker that switches thinking off, as found in step 1 | + +> **NOTE:** +> The table is a starting point only. Templates differ between versions and between fine-tunes, so use what step 1 returns for the model at hand. + +**Step 3: verify with a single request** before scanning: + +```bash +curl -s http://-predictor..svc.cluster.local/v1/completions \ + -H 'Content-Type: application/json' \ + -d '{"model":"","prompt":"","max_tokens":80}' +``` + +The reply should read as normal conversation. Echoed prompt text, visible role markers or an unrelated answer all mean the template is wrong. + +### Selecting probes + +* `garak --list_probes` lists every probe with its tier; tier 1 deserves the most attention. +* `--spec probes.all,tier:1` runs the tier 1 probes only; `--spec tag:owasp:llm01` selects by OWASP LLM Top 10 category. +* These probes reach the internet or the Hugging Face Hub at run time, so do not select them in an offline environment: `visual_jailbreak`, `fileformats`, `audio`. + +### Probes for other languages and for business scenarios + +garak's built-in probes are mostly English. For other languages, and for risks specific to your own RAG or agent applications, write your own probes: create a Python module, subclass `garak.probes.Probe`, set `self.prompts` in `__init__` and name a `primary_detector`. See "Writing a Probe" in the garak documentation. + +garak loads probes from its own package directory, and that directory returns to its original state when a Workspace is recreated. Keep the probe sources on the volume, for example under `~/garak/probes/`, and copy them into the package directory in each new Workspace: + +```bash +cp ~/garak/probes/*.py /opt/app-root/garak/venv/lib/python3.12/site-packages/garak/probes/ +garak --config ~/garak/scan.yaml --spec probes. +``` + +Once the probes are stable, ask Alauda to add them to the image so that they ship with it. + +### Using an LLM as the judge detector + +The `detectors.judge.*` detectors ask another model whether the attack goal was reached. That is more accurate than keyword matching, especially for non-English output. It needs a working chat endpoint: + +```yaml +plugins: + detectors: + judge: + detector_model_type: openai.OpenAICompatible + detector_model_name: + detector_model_config: + uri: http://-predictor..svc.cluster.local/v1/ + stop: [] +``` + +Use a judge model larger than the model under test. + +## Image upgrades + +* garak releases roughly monthly, mostly adding probes; the bundled detector models and datasets change rarely. Alauda publishes a new image tag per garak version. To upgrade: pull the new tag, push it to the Private Registry, change `image` in the WorkspaceKind and re-apply it (or add a second WorkspaceKind so both versions remain available), then have users switch their Workspace. +* Scan configurations, custom probes and past reports live on the Workspace volume and survive an image version change. +* Probe names and configuration keys can change between garak versions, so run the smoke test after an upgrade to confirm the existing configuration still works. + +## Summary + +garak and all of its offline assets are packaged as an Alauda AI Workbench image published by Alauda. Once the image has passed through the customer's image import process into the Private Registry, and an administrator has imported the WorkspaceKind once, users create a Workspace from the Workbench console and scan any inference service in the cluster. No internet access is needed at scan time and no task scheduling component is involved. Scan configurations and reports are kept on the Workspace volume, where they can be read in JupyterLab or downloaded for archiving; scanning a different service only takes a change of the service address and model name in `scan.yaml`.

The shipped sample is the Qwen3 template. For another model, derive it as follows. +The configuration above scans the model endpoint directly, which measures the robustness of the model itself. That is the right target for model selection, for comparing versions and for a model card, but it is not the whole production risk: system prompt leakage, guardrail bypass, indirect injection through retrieved documents and unauthorised tool calls only appear once the model sits behind an application. A model that looks weak on its own may be well contained by an application, and a model that looks safe may still be exploitable because the application concatenates user input into its system prompt. -**Step 1: read the template from the model files.** +Two ways to move closer to production risk, in increasing order of fidelity. -```bash -kubectl -n exec -c kserve-container -- python3 -c " -import json -d = json.load(open('/mnt/models/tokenizer_config.json')) -print(d.get('chat_template', '(see chat_template.jinja)')) -" -``` +**Send the production system prompt with the scan.** Keep scanning the model endpoint, but have garak pass the same system prompt the application uses, so the result reflects the model plus your prompt engineering: -Look for the `add_generation_prompt` branch; that is the generation prompt. If the model has a thinking mode (Qwen3, GLM-4.5 and similar), also look for what is appended when `enable_thinking` is false and include it — otherwise the model emits a long block of reasoning first and the detectors count that text in their verdicts. +```yaml +run: + system_prompt: "" +``` -**Step 2: write it into `prompt`**, with `$INPUT` where the user message goes. Common shapes: +garak sends it as a system message for generators that support chat, unless a probe overrides it. -| Model | prompt template | -| --- | --- | -| Qwen3 family | `"<\|im_start\|>user\n$INPUT<\|im_end\|>\n<\|im_start\|>assistant\n\n\n\n\n"` | -| Zhipu GLM-4 family | `"[gMASK]<\|user\|>\n$INPUT<\|assistant\|>\n"` | -| Zhipu GLM-4.5 and later | the GLM-4 shape plus the marker that switches thinking off, as found in step 1 | +**Scan the application's own endpoint.** Point garak at the HTTP API of the chatbot, RAG service or agent with the `rest` generator. The request and response shapes are yours, so they have to be described in the configuration: -> **NOTE:** -> The table is a starting point only. Templates differ between versions and between fine-tunes, so use what step 1 returns for the model at hand. Using the chat endpoint avoids this work altogether. +```yaml +plugins: + target_type: rest + target_name: my-rag-app + generators: + rest: + RestGenerator: + uri: http://my-rag-app..svc.cluster.local/api/v1/chat + method: post + headers: + Content-Type: application/json + Authorization: Bearer $KEY # taken from REST_API_KEY + req_template_json_object: + question: $INPUT # $INPUT is replaced with the attack prompt + response_json: true + response_json_field: $.answer # JSONPath to the answer in the response + request_timeout: 120 +``` -**Step 3: verify with a single request** before scanning: +With this target the scan covers the application's system prompt, its guardrails, its retrieval context and its tools — the surface an attacker actually reaches. Probes such as `sysprompt_extraction`, `latentinjection` and `exploitation` become far more meaningful here than against a bare model. -```bash -curl -s http://-predictor..svc.cluster.local/v1/completions \ - -H 'Content-Type: application/json' \ - -d '{"model":"","prompt":"","max_tokens":80}' -``` +> **NOTE:** +> The `rest` generator sends only the last message of a conversation, so multi-turn probes (`goat`, `fitd`, `atkgen`, `tap`) are silently reduced to their final turn and no longer test what they are meant to test. Single-turn probes are unaffected. To cover multi-turn attacks against an application, write a generator that keeps the application's session, subclassing `garak.generators.base.Generator` and implementing `_call_model`. -The reply should read as normal conversation. Echoed prompt text, visible role markers or an unrelated answer all mean the template is wrong. +Comparing a scan with the guardrails enabled against one with them disabled quantifies what the guardrails actually stop. ### Selecting probes From d4e625064bfd27d8f4d7c5398a043147db061026 Mon Sep 17 00:00:00 2001 From: luohua13 Date: Thu, 24 Sep 2026 06:31:46 +0000 Subject: [PATCH 07/11] docs(ai): state the image address instead of registry CLI commands Co-Authored-By: Claude Opus 5 (1M context) --- .../AI/LLM_Security_Scanning_with_garak_on_Workbench.md | 8 +------- 1 file changed, 1 insertion(+), 7 deletions(-) diff --git a/docs/en/solutions/AI/LLM_Security_Scanning_with_garak_on_Workbench.md b/docs/en/solutions/AI/LLM_Security_Scanning_with_garak_on_Workbench.md index 11fd1cdcf..dc6ab1828 100644 --- a/docs/en/solutions/AI/LLM_Security_Scanning_with_garak_on_Workbench.md +++ b/docs/en/solutions/AI/LLM_Security_Scanning_with_garak_on_Workbench.md @@ -33,13 +33,7 @@ This solution provides a prebuilt Alauda AI Workbench image with garak and all o ### Image -`alaudadockerhub/garak-workbench:0.17.0-20260922` (digest `sha256:d1cc22470189dfe4b341f1c2507897d60399f5257ec936bcd14da4f38e99440a`, 5.3 GB).

Alauda can provide an image for a newer garak version on request; update `image` in the WorkspaceKind to the new address and have users switch their Workspace. ## Summary From 13e3783dfa101c3c54203017d08af718050c5b57 Mon Sep 17 00:00:00 2001 From: luohua13 Date: Thu, 24 Sep 2026 07:54:40 +0000 Subject: [PATCH 11/11] docs(ai): run the scan in the foreground Co-Authored-By: Claude Opus 5 (1M context) --- ...LM_Security_Scanning_with_garak_on_Workbench.md | 14 +++----------- 1 file changed, 3 insertions(+), 11 deletions(-) diff --git a/docs/en/solutions/AI/LLM_Security_Scanning_with_garak_on_Workbench.md b/docs/en/solutions/AI/LLM_Security_Scanning_with_garak_on_Workbench.md index c65d3c369..004831792 100644 --- a/docs/en/solutions/AI/LLM_Security_Scanning_with_garak_on_Workbench.md +++ b/docs/en/solutions/AI/LLM_Security_Scanning_with_garak_on_Workbench.md @@ -323,22 +323,14 @@ Each line is one probe/detector pair. `ok on 0/6` means none of the 6 responses ### Running the scan -A full scan takes a while, so run it in the background so that a disconnected terminal does not abort it: - ```bash cd ~/garak -nohup garak --config scan.yaml > scan.log 2>&1 & -``` - -Follow the progress: - -```bash -tail -f ~/garak/scan.log +garak --config scan.yaml ``` -The 11 probe entries in the sample configuration expand to 21 probes and complete in about 15 minutes at 8 concurrent requests.
