+# BUSINESS POSTURE
+
+The **Fabric Agent Action** project aims to streamline the integration of [Fabric Patterns](https://github.com/danielmiessler/fabric/tree/main/patterns) into GitHub workflows. By leveraging an agent-based approach, it automates complex workflows using Large Language Models (LLMs). The primary business priorities and goals include:
+
+- **Simplifying Workflow Automation**: Provide developers with an easy-to-use GitHub Action that seamlessly incorporates Fabric Patterns into existing workflows, enhancing productivity and reducing manual effort.
+- **Enhancing Flexibility**: Support multiple LLM providers (OpenAI, OpenRouter, Anthropic) to offer users the choice based on preference and availability.
+- **Customizable Agent Behavior**: Allow users to select agent types and customize behaviors to suit various workflow needs.
+- **Optimizing Performance**: Enable inclusion or exclusion of specific Fabric Patterns to comply with model limitations and optimize performance.
+
+**Business Risks**:
+
+- **Unauthorized Usage Leading to Increased Costs**: Without proper security controls, unauthorized users could trigger the action, causing unexpected API usage and escalating costs.
+- **Security Vulnerabilities**: Insufficient access control could expose workflows to malicious actors, risking code integrity and data security.
+- **Reliance on External Services**: Dependence on external LLM providers may introduce risks related to availability, compliance, and data privacy.
+
+# SECURITY POSTURE
+
+**Existing Security Controls**:
+
+1. **Security Control**: **Access Control Patterns** implemented in workflows using conditional statements to restrict action execution.
+
+   - *Implemented in:* README.md under **Security** section.
+   - *Description:* Conditions like `github.event.comment.user.login == github.event.repository.owner.login` ensure only authorized users can trigger actions.
+
+2. **Security Control**: **Secure Storage of API Keys** using GitHub Secrets.
+
+   - *Implemented in:* Action configuration and usage instructions.
+   - *Description:* API keys for LLM providers are stored securely to prevent unauthorized access.
+
+3. **Security Control**: **Environment Variable Management** to prevent exposure of sensitive information.
+
+   - *Implemented in:* `entrypoint.sh` and action workflows.
+   - *Description:* Ensures sensitive data is not printed in logs or error messages.
+
+**Accepted Risks**:
+
+1. **Accepted Risk**: Potential for unauthorized usage if workflows are not properly secured, leading to increased API costs.
+
+**Recommended Security Controls**:
+
+1. **Security Control**: **Input Validation** to sanitize and validate all inputs provided to the action, preventing injection attacks or misuse.
+2. **Security Control**: **Enhanced Authentication Mechanisms** within the action to supplement workflow-level access controls.
+3. **Security Control**: **Audit Logging** to monitor and log action usage for audit trails and anomaly detection.
+
+**Security Requirements**:
+
+- **Authentication**:
+
+  - Ensure that only authenticated users can trigger workflows.
+  - Use GitHub's authentication mechanisms and verify user identities.
+
+- **Authorization**:
+
+  - Implement strict permission checks to confirm that users have the necessary rights to execute actions.
+  - Limit action execution to repository collaborators or specified roles.
+
+- **Input Validation**:
+
+  - Validate all input data to prevent malicious input from causing unintended behavior.
+  - Implement checks for command injection, script injection, and other common vulnerabilities.
+
+- **Cryptography**:
+
+  - Use HTTPS for all communications with LLM providers to ensure data in transit is encrypted.
+  - Securely store and handle API keys and secrets using GitHub Secrets.

+   - **Checkout Code**: Repository code is checked out.
+   - **Install Python and Poetry**: Python environment is set up using Poetry.
+   - **Install Dependencies**: Project dependencies are installed.
+   - **Code Quality Checks**:
+
+     - **Ruff**: Linting tool checks for code quality issues.
+     - **MyPy**: Static type checker validates type annotations.
+     - **Bandit**: Security linter scans for common security issues.
+     - **Hadolint**: Linter checks the Dockerfile for best practices.
+
+   - **Testing**:
+
+     - **Pytest**: Runs unit tests.
+     - **Integration Tests**: Docker image is built and tested.
+
+4. **Docker Image Build**:
+
+   - Using `publish.yaml`, the Docker image is built upon tagging a release.
+   - Image is pushed to GitHub Container Registry.

+# RISK ASSESSMENT
+
+- **What are the critical business processes we are trying to protect?**
+
+  - Integrity and reliability of automated workflows.
+  - Secure handling of API keys and sensitive data.
+  - Prevention of unauthorized access and execution of actions.
+
+- **What data are we trying to protect and what is their sensitivity?**
+
+  - **API Keys for LLM Providers**: High sensitivity; unauthorized access could lead to misuse and cost implications.
+  - **Source Code and Workflow Configurations**: Medium sensitivity; contains logic and secrets that could be exploited.
+  - **User Input Data**: Medium sensitivity; may contain proprietary or confidential information.
+
+# QUESTIONS & ASSUMPTIONS
+
+**Questions**:
+
+1. Are additional authentication mechanisms needed beyond GitHub's built-in controls to enhance security?
+2. How are API keys rotated and managed to minimize the risk of key compromise?
+3. Are there plans to support additional LLM providers or self-hosted models for greater flexibility?
+4. What are the compliance requirements concerning data processing with external LLM services?
+
+**Assumptions**:
+
+- It is assumed that users will properly configure workflow access controls as outlined in the documentation.
+- API keys are securely stored using GitHub Secrets and are not exposed in logs or outputs.
+- LLM providers comply with relevant data protection regulations (e.g., GDPR, CCPA).
+- The action will primarily run in GitHub-hosted runners unless explicitly configured otherwise.
