Threat-model an OpenClaw deployment, constrain access and tools, protect credentials, and rehearse incident response.

Intermediate75 minutes7 lessonsNo login

WHO THIS IS FOR

Operators running OpenClaw with access to files, browsers, APIs, messaging channels or shell execution.

Prerequisites

  • A working OpenClaw installation or a written deployment design
  • Access to the current OpenClaw configuration and service status
  • A safe test environment that does not contain production credentials

BY THE END

You will be able to

  1. Model realistic threats across messages, content, tools and credentials
  2. Reduce Gateway, channel and tool exposure
  3. Apply layered prompt-injection controls rather than trusting prompts alone
  4. Audit secret storage and rotation paths
  5. Create a practical incident-response runbook
LESSON 01

1. Build the threat model

Outcome: Identify assets, trust boundaries, attackers and high-consequence actions.

  • List every source of untrusted text: direct messages, groups, web pages, email, documents, tool output and copied prompts.
  • List every reachable asset: files, credentials, browser sessions, internal services, cloud APIs and other people.
  • Prioritise impact over novelty. Credential theft, unauthorised messages, destructive shell actions and data disclosure matter more than clever jailbreak wording.
  • Distinguish model failure from control failure: a model may follow malicious text, but permissions determine the damage it can cause.

PRACTICAL TASK

Create a table with four columns: untrusted source, reachable asset, possible action and enforcing control. Highlight any row with no enforcing control.
Self-check: Why is “the model should refuse” an incomplete mitigation?

Models are probabilistic and prompt injection targets their instruction following. Hard permissions, isolation, approvals and access controls must limit the outcome when refusal fails.

LESSON 02

2. Lock down access

Outcome: Restrict who can reach the Gateway and who can invoke the agent through channels.

  • Keep the Gateway on loopback unless remote access is explicitly required.
  • Use Gateway authentication even on trusted local machines; local compromise and browser clients still cross a control boundary.
  • Default direct messages to pairing or an explicit allowlist and keep groups constrained.
  • Review every reverse proxy, tunnel and firewall rule that can expose the Gateway or control UI.

PRACTICAL TASK

Document the listening address, authentication method, remote path and authorised channel senders. Remove any exposure you cannot explain.
Self-check: What are the two separate access decisions for a messaging channel?

First, whether the channel account is linked to the Gateway; second, whether a sender or group is authorised to invoke the agent.

LESSON 03

3. Contain prompt injection

Outcome: Design workflows that remain bounded when external content contains hostile instructions.

  • Treat retrieved content as data, never as authority to change the task or permissions.
  • Separate collection from action. A reading step should not also possess broad write or execution rights.
  • Require explicit confirmation for messages, purchases, deletion, credential use and changes to external systems.
  • Constrain outputs with allowlists and deterministic validation where the workflow permits it.

PRACTICAL TASK

Take one workflow that reads external content. Insert a fake instruction asking the agent to send data elsewhere and confirm the workflow cannot perform that action.
Self-check: What is the strongest practical defence against indirect prompt injection?

Layered containment: minimise tool authority, separate untrusted reading from privileged action, validate outputs and require approval for consequential side effects.

LESSON 04

4. Reduce tool blast radius

Outcome: Give each workflow only the capabilities and filesystem/network reach it needs.

  • Tool policy controls which capabilities may be invoked; sandboxing controls where supported execution occurs; elevated access bypasses isolation and must stay exceptional.
  • Prefer read-only roots, dedicated working directories and narrowly scoped API credentials.
  • Block arbitrary shell and unrestricted browser sessions from agents that only need retrieval or summarisation.
  • Test denied operations so you know controls work before relying on them.

PRACTICAL TASK

For one agent, list every enabled tool and justify it in one sentence. Remove or deny anything without a current task-level reason.
Self-check: Do sandboxing and tool allowlists solve the same problem?

No. Tool policy decides what may be called; sandboxing limits the environment in which supported actions run. Use both, and avoid elevated execution unless explicitly necessary.

LESSON 05

5. Isolate and rotate secrets

Outcome: Keep credentials out of prompts, workspace files, logs and broad shared profiles.

  • Use the supported credential and environment mechanisms rather than embedding tokens in instructions or JSON examples.
  • Scope credentials by provider, environment and agent where possible.
  • Prevent workspace backups, screenshots, logs and support bundles from capturing secrets.
  • Know the revocation path before an incident. An untested rotation plan is wishful thinking.

PRACTICAL TASK

Inventory each credential the deployment can reach, its scope, storage location, owner and revocation URL. Rotate one low-risk test credential end to end.
Self-check: Why is a private Git repository not an acceptable secret store?

Private repositories still replicate history and broaden access. Once committed, secrets persist in history and backups; use purpose-built credential storage instead.

LESSON 06

6. Audit and monitor behaviour

Outcome: Detect unsafe configuration and reconstruct what happened without logging unnecessary secrets.

  • Run the current security audit and inspect findings rather than treating a command exit as proof of safety.
  • Monitor Gateway health, authentication failures, channel churn, tool approvals and unexpected outbound actions.
  • Retain enough session and service evidence to investigate incidents, but set limits for personal or confidential content.
  • Baseline normal behaviour so unusual activity is visible.

PRACTICAL TASK

Run `openclaw security audit --deep`, triage each finding and record either the remediation or the reason it is accepted. Redact secrets from the record.
Self-check: What does a clean security audit prove?

Only that the audit found no known configuration issue in the checks it performs. It does not prove the model, workflow, host, credentials or external integrations are secure.

LESSON 07

7. Rehearse incident response

Outcome: Contain a suspected compromise without destroying the evidence needed to understand it.

  • Stop or isolate the affected Gateway and privileged workflows first.
  • Revoke exposed provider, channel and external-service credentials from a trusted device.
  • Preserve relevant configuration, service logs, session evidence and timestamps before wiping state.
  • Rebuild from a known-good baseline, rotate trust and verify each integration before reconnecting it.

PRACTICAL TASK

Write a one-page runbook naming who can stop the service, where credentials are revoked, what evidence is preserved and the conditions for reconnecting channels.
Self-check: What is the first objective after credible evidence of credential theft?

Contain further access and revoke the exposed credential from a trusted path, while preserving enough evidence to establish scope and cause.

COURSE COMPLETE

Use the work, not the badge.

You should now have practical notes, tests and a safer operating baseline. Revisit the course after major OpenClaw releases: commands and configuration can change.
