# Confirmation Mode and Security Analyzers
OpenHands provides a security framework to help protect users from potentially risky actions through **Confirmation Mode** and **Security Analyzers**. This system analyzes agent actions and prompts users for confirmation when high-risk operations are detected.
## Overview
The security system consists of two main components:
1. **Confirmation Mode**: When enabled, the agent will pause and ask for user confirmation before executing actions that are flagged as high-risk by the security analyzer.
2. **Security Analyzers**: These are modules that evaluate the risk level of agent actions and determine whether user confirmation is required.
## Configuration
### CLI
In CLI mode, confirmation is enabled by default. You will have an option to uses the LLM Analyzer and will automatically confirm LOW and MEDIUM risk actions, only prompting for HIGH risk actions.
## Security Analyzers
OpenHands includes multiple analyzers:
- **No Analyzer**: Do not use any security analyzer. The agent will prompt you to confirm *EVERY* action.
- **LLM Risk Analyzer** (default): Uses the same LLM as the agent to assess action risk levels
- **Invariant Analyzer**: Uses Invariant Labs' policy engine to evaluate action traces against security policies
### LLM Risk Analyzer
The default analyzer that leverages the agent's LLM to evaluate the security risk of each action. It considers the action type, parameters, and context to assign risk levels.
### Invariant Analyzer
An advanced analyzer that:
- Collects conversation events and parses them into a trace
- Checks the trace against an Invariant policy to classify risk (low, medium, high)
- Manages an Invariant server container automatically if needed
- Supports optional browsing-alignment and harmful-content checks
## How It Works
1. **Action Analysis**: When the agent wants to perform an action, the selected security analyzer evaluates its risk level.
2. **Risk Assessment**: The analyzer returns one of three risk levels:
- **LOW**: Action proceeds without confirmation
- **MEDIUM**: Action proceeds without confirmation (may be configurable in future)
- **HIGH**: Action is paused, and user confirmation is requested
3. **User Confirmation**: For high-risk actions, a confirmation dialog appears with:
- Description of the action
- Risk assessment explanation
- Options to approve or deny action
4. **Action Execution**: Based on user response:
- **Approve**: Action proceeds as planned
- **Deny**: Action is cancelled

# 🔐 Security Risk Policy
When using tools that support the security_risk parameter, assess the safety risk of your actions:
{% if cli_mode %}
- **LOW**: Safe, read-only actions.
- Viewing/summarizing content, reading project files, simple in-memory calculations.
- **MEDIUM**: Project-scoped edits or execution.
- Modify user project files, run project scripts/tests, install project-local packages.
- **HIGH**: System-level or untrusted operations.
- Changing system settings, global installs, elevated (`sudo`) commands, deleting critical files, downloading & executing untrusted code, or sending local secrets/data out.
{% else %}
- **LOW**: Read-only actions inside sandbox.
- Inspecting container files, calculations, viewing docs.
- **MEDIUM**: Container-scoped edits and installs.
- Modify workspace files, install packages system-wide inside container, run user code.
- **HIGH**: Data exfiltration or privilege breaks.
- Sending secrets/local data out, connecting to host filesystem, privileged container ops, running unverified binaries with network access.
{% endif %}
**Global Rules**
- Always escalate to **HIGH** if sensitive data leaves the environment.

## Implemented Security Analyzers
### LLM Risk Analyzer (Default)
The LLM Risk Analyzer is the default security analyzer that leverages LLM-provided risk assessments. It respects the `security_risk` attribute that can be set by the LLM when generating actions, allowing for intelligent risk assessment based on the context and content of each action.
Features:
* Uses LLM-provided risk assessments (LOW, MEDIUM, HIGH)
* Automatically requires confirmation for HIGH-risk actions
* Respects confirmation mode settings for MEDIUM and LOW-risk actions
* Lightweight and efficient - no external dependencies
* Integrates seamlessly with the agent's decision-making process
The LLM Risk Analyzer checks if actions have a `security_risk` attribute set by the LLM and maps it to the appropriate `ActionSecurityRisk` level. If no risk assessment is provided, it defaults to UNKNOWN.
### Invariant
It uses the [Invariant Analyzer](https://github.com/invariantlabs-ai/invariant) to analyze traces and detect potential issues with OpenHands's workflow. It uses confirmation mode to ask for user confirmation on potentially risky actions.
