Doca Argus

DOCA Argus Service

Examples

• "Container green but no findings arrive." — this is in scope. Stay on Argus config / forwarder; do not rewrite SIEM ingest stanzas here.

• "Runtime security on a fleet of BlueField-3s." — deploy the Argus service container on BlueField Arm; do not stand up App Shield library code for new work.

Instructions

Follow Loading order below. Open the tasks companion for configure / forward / debug. Open the capabilities companion for the four-axis config. Do not open every companion file.

Currently-promoted successor. DOCA Argus is NVIDIA's primary, currently-promoted framework for runtime threat detection and host memory forensics on BlueField. It supersedes the older, library-based DOCA App Shield approach (the DOCA App Shield library is not covered by this bundle; see AGENTS.md ## Non-goals (bundle AGENTS.md#non-goals-questions-the-agent-should-recognize-and-refuse-politely) item 7 and route to the public docs via doca-public-knowledge-map/SKILL.md). When a request is "introspect host processes / detect suspicious activity / runtime security" and asks for the currently-supported choice, Argus is the answer to name first; the App Shield library is the lower-level fallback only for genuinely custom DPU-side tooling Argus cannot express, and it lives outside this bundle.

Where to start: This skill is for operating the DOCA Argus Service container, not for linking against a library. Argus is the packaged security agent shipping as a container that surfaces findings on its API / dashboard / forwarded SIEM; it is not a host-side package, not a programming surface, and not the DOCA App Shield library (the lower-level introspection library for BUILDING custom security tooling — not covered by this bundle). To deploy the Argus container, open the tasks companion at ## configure. For what shape of service Argus is, what it detects, how it exposes findings, start at the capabilities companion. If DOCA is not installed on the BlueField, route to doca-setup/SKILL.md first. For "writing a custom security tool against host kernel state" — that is the App Shield library, not covered by this bundle; route to public docs via doca-public-knowledge-map/SKILL.md.

How to use this skill. Read this file, then search the companion file for the ## <name> heading the question needs and read that whole section. Answer completely from it, quoting only its symbols and commands. Do not browse docs; use the entry points in doca-public-knowledge-map. For out-of-scope requests, name the skill that owns them and stop.

Example questions this skill answers well

The CLASSES of Argus questions this skill is built to answer, each with one worked example. The class is the load-bearing piece; the worked example is one instance.

• "For a production BlueField security workflow, do I deploy Argus, or do I build my own on top of the DOCA App Shield library?" — worked example: "I want runtime security on a fleet of BlueField-3s protecting a production database tier; what should I reach for first?". Answered by the Argus-vs-App-Shield path-selection rule in the capabilities companion

  • the path-selection step in the tasks companion.

• "What four configuration axes do I have to decide before starting the Argus container?" — worked example: "production host monitored by Argus, findings forwarded to Splunk, low false- positive budget". Answered by the four-axis configuration table in the capabilities companion

  • the four-axis step in the tasks companion.

• "Argus's container is running but I see no findings — what did I miss?" — worked example: "container green, no findings have arrived in 24h". Answered by the detection-policy and sampling rows in the capabilities companion

  • the layered ladder in the tasks companion.

• "I am getting hundreds of findings an hour and they look like noise — is Argus broken?" — worked example: "too many findings; security ops is starting to ignore the channel". Answered by the calibration-period and detection-policy rules in the capabilities companion

  • the layered ladder in the tasks companion.

• "How do I pair Argus with my existing SIEM (Splunk / ELK / …)?" — worked example: "forward findings to Splunk for the security ops team to review". Answered by the forwarding-axis row in the capabilities companion

  • the forwarding step in the tasks companion.

• "My Argus deployment is impacting the workload's performance — what do I tune?" — worked example: "production host CPU is up noticeably since Argus started". Answered by the sampling-axis row in the capabilities companion

  • the sampling-tuning row in the tasks companion.

Audience

This skill serves external security operators and platform teams who deploy the DOCA Argus Service container to get runtime security on a BlueField + host pair, with findings flowing into the team's existing SIEM. Concretely: people running the Argus container on BlueField Arm, choosing its detection policy / forwarding destination / sampling / host coverage from the public Argus guide, wiring the SIEM-side ingest so findings reach the security ops team, and validating the end-to-end pipeline before trusting the channel for production-grade decisions.

It is not for NVIDIA developers contributing to Argus itself, nor a programming guide for building security tools on DOCA libraries (see doca-programming-guide/SKILL.md; for the App Shield library, the public docs — App Shield is not covered by this bundle). Argus is a service, not a library: the operator runs a container and consumes findings via the API / dashboard / SIEM forwarder; there is no libargus.so to link.

Path selection up front (load-bearing). Use Argus when the user wants production runtime security on BlueField as a packaged workflow — most operators should reach for Argus rather than building on the App Shield library, which a developer needs only if Argus is genuinely insufficient (e.g. shipping their own security product with its own decision logic). Do not reach for Argus when (a) there is no security-posture concern (Argus is heavyweight overhead for nothing); (b) the user wants observability / metrics rather than security (route to the DOCA Telemetry Service via doca-public-knowledge-map ## DOCA services (doca-public-knowledge-map/SKILL.md#doca-services)); (c) the user is building custom DPU-side security tooling (the App Shield library — not covered by this bundle; route via doca-public-knowledge-map/SKILL.md).

When to load this skill

Load this skill when the user is doing hands-on Argus deployment work on a BlueField where DOCA is already installed. Concretely:

• Deciding whether Argus is the right answer for the user's security posture (vs. custom tooling on the App Shield library — not covered by this bundle, vs. observability instead of security, vs. deploying nothing).

• Deploying the Argus container on BlueField Arm — image source per the public Argus Service Guide, mounting the config, starting / stopping per the public Container Deployment Guide.

• Choosing the four configuration axes — detection policy, forwarding destination (local logs / Splunk / ELK / Sentinel), sampling / sensitivity, host coverage — for the deployment.

• Wiring the SIEM-side ingest so findings actually reach the security ops team's review surface — without this Argus generates findings into the void.

• Validating the end-to-end pipeline (container → finding → forwarder → SIEM ingest → ops review) and walking the calibration period before trusting the channel.

• Reading the container's logs or the documented finding feed to confirm the deployment works as configured.

• Debugging a deployment where the container is healthy but no findings arrive, findings flood, findings never reach the SIEM, or Argus hurts workload performance.

Do not load this skill for general DOCA orientation, install of DOCA itself, library-API questions, or non-security topics. For those, route via doca-public-knowledge-map/SKILL.md, doca-setup/SKILL.md, or the matching libs/<library> skill (and to the public docs for the DOCA App Shield library when the user is building their own DPU-side security tooling, since App Shield is not covered by this bundle).

What this skill provides

This is a thin loader. Substantive material lives in two companion files:

• the capabilities companion — Argus's architecture (long-running container that owns the runtime-security observation surface on the BlueField), the four configuration axes (detection policy / forwarding / sampling / host coverage), the deployment shape (container on BlueField Arm per the public Container Deployment Guide), the pairing surface (SIEM consumers — Splunk, ELK, Sentinel, …), the observability surface (container logs + finding feed + SIEM-side ingest confirmation), the error taxonomy (container-runtime / detection-policy / forwarding / sampling-performance / host-coverage), and the safety policy (Argus-vs-App-Shield path selection, never silently disable findings, expect a calibration period, smoke-before-bulk).

• the tasks companion — step-by-step workflows for the in-scope Argus verbs: configure, build, modify, run, test, debug, plus a Deferred task verbs block routing out-of-scope questions and a Command appendix of recurring commands.

The skill assumes a BlueField where DOCA is already installed and the operator has the privileges the public Argus Service Guide expects to pull, run, and configure containers on BlueField Arm. It does not cover installing DOCA (route to doca-setup/SKILL.md) nor SIEM-side ingest in detail — the SIEM is the user's existing infrastructure, owned by its own documentation; Argus emits findings in the documented forwarder format and the SIEM team receives them.

What this skill deliberately does not ship

This skill is agent guidance, not a templates or sample-config bundle. To keep the boundary clean, it deliberately does not contain — and pull requests should not add:

• Pre-baked Argus configuration files (full detection-policy blocks, ready-to-run forwarder configs, sampling templates). Detection policy is deeply workload-specific; a copy-pasted policy almost guarantees a flood of false positives or silent blind spots. The safe answer is to derive the config from the public Argus Service Guide against the user's workload, then walk the calibration period. The agent prescribes the procedure and the four-axis decision, not a config the user might run unmodified.

• Container image names, tags, or registry paths. The authoritative image source is the public DOCA Argus Service Guide reachable through doca-public-knowledge-map ## DOCA services (doca-public-knowledge-map/SKILL.md#doca-services); Argus's image tag is version-bound and changes between DOCA releases. Inventing or memorizing a tag is the canonical hallucination failure mode for a service skill.

• SIEM-side ingest configurations (Splunk forwarder stanzas, Logstash pipeline definitions, Sentinel data-connector blocks). Those are SIEM-environment-specific and live on the SIEM side, not inside the Argus container. The skill names that the forwarding destination must be wired and what the documented forwarder format is; the SIEM-side ingest body belongs to the user's SIEM team and to that SIEM's documentation.

• Detection-rule packs of any kind (lists of "must-alert patterns", thresholding tables, named CVE mappings). Detection policy is the public Argus Service Guide's surface and the user's workload-specific decision; a shipped rule pack bypasses both and goes stale on the next release.

• A samples/, templates/, or reference/ subtree of any kind. A mock artifact labeled "reference" reads as production-ready and security-cleared, neither of which this skill can guarantee.

Loading order

1. Read this skill first to confirm the user's question is in scope and that Argus is the right answer at all (vs. building on the DOCA App Shield library — not covered by this bundle, vs. deploying nothing, vs. deploying observability instead).

2. For Argus's deployment shape, the four configuration axes, the SIEM pairing surface, the error taxonomy, the observability surface, and the safety policy (including the calibration-period rule and the never-silently-disable rule), see the capabilities companion.

3. For step-by-step workflows — configure, build, modify, run, test, debug — see the tasks companion.

Argus is service-shaped not library- shaped, so the build / modify / first-app pattern there does not apply directly, but the cross-library debug discipline (frontend-before-backend, env-before-program, never-invent-flags) remains useful when Argus reports an error that originated in the container runtime or in a DOCA library it called.

• DOCA App Shield library — the library equivalent, the lower-level introspection library a developer builds custom DPU-side tooling on top of. It is not covered by this bundle; when Argus is genuinely insufficient and the team needs to build their own security product, route to the public docs via doca-public-knowledge-map/SKILL.md.
