Okay, let's create a design document for the Artifactory User Plugins project.
Business Priorities and Goals:
- Enhance Extensibility: Allow users to customize and extend JFrog Artifactory's functionality without modifying the core application. This enables tailored workflows and integrations specific to an organization's needs.
- Improve Operational Efficiency: Enable automation of tasks within Artifactory, reducing manual intervention and potential errors.
- Maintain Core Stability: Provide a safe and controlled way to add functionality, ensuring that user-provided code does not compromise the stability or security of the main Artifactory instance.
- Foster Community Contributions: Encourage a community around Artifactory where users can share and reuse plugins, accelerating innovation and problem-solving.
- Reduce Vendor Lock-in: By allowing custom integrations, users can more easily connect Artifactory with other tools in their ecosystem, reducing reliance on a single vendor's solutions.
Most Important Business Risks:
- Security Vulnerabilities in Plugins: User-developed plugins could introduce security vulnerabilities, potentially exposing sensitive data or compromising the Artifactory instance.
- Performance Degradation: Poorly written plugins could negatively impact Artifactory's performance, leading to slowdowns or instability.
- Maintenance Overhead: Managing a large number of plugins, especially those developed by third parties, could create a significant maintenance burden.
- Compatibility Issues: Plugins might become incompatible with newer versions of Artifactory, requiring updates and potentially causing disruptions.
- Lack of Support: Community-developed plugins might lack proper support, leaving users with unresolved issues.
Existing Security Controls:
- security control: Plugin Isolation: Artifactory executes user plugins in a sandboxed environment (Groovy sandbox) to limit their access to the core system and prevent malicious or accidental damage. Described in repository README.md.
- security control: Permission Control: Artifactory provides a mechanism to control which users and groups can deploy, execute, and manage plugins. Described in repository README.md.
- security control: API for Auditing: Artifactory likely provides APIs or logging mechanisms to track plugin activity, aiding in auditing and incident response. (Assumption, needs verification).
- security control: Code Review (Optional): Organizations can implement a code review process for internally developed plugins before deployment. This is a procedural control, not a technical one inherent to the project.
Accepted Risks:
- accepted risk: Third-Party Plugin Risk: Users deploying plugins from untrusted sources accept the risk of potential vulnerabilities or malicious code within those plugins.
- accepted risk: Plugin-Induced Instability: While the sandbox aims to mitigate this, there's an accepted risk that a poorly written plugin could still cause performance issues or instability in specific scenarios.
Recommended Security Controls:
- security control: Static Code Analysis: Integrate static code analysis tools into the plugin development and deployment workflow to automatically scan for common vulnerabilities and coding errors.
- security control: Dynamic Analysis: Consider implementing dynamic analysis (runtime testing) of plugins in a staging environment to identify potential security or performance issues before production deployment.
- security control: Plugin Signing: Implement a mechanism to digitally sign plugins, allowing Artifactory to verify the authenticity and integrity of plugins before execution.
- security control: Dependency Scanning: Scan plugin dependencies for known vulnerabilities.
- security control: Content Trust: Enforce content trust to ensure that only signed and verified plugins can be executed.
Security Requirements:
-
Authentication:
- Plugins should leverage Artifactory's existing authentication mechanisms. Plugins should not implement their own authentication.
- If a plugin interacts with external systems, it should use secure credential storage mechanisms (e.g., Artifactory's encrypted properties or a dedicated secrets management solution).
-
Authorization:
- Plugins should respect Artifactory's existing permission model.
- Plugins should implement granular authorization checks if they introduce new actions or resources. Use the provided APIs to check user permissions.
-
Input Validation:
- Plugins must thoroughly validate all inputs received from users, other plugins, or external systems.
- Use whitelisting (allowlisting) rather than blacklisting (denylisting) whenever possible.
- Sanitize inputs to prevent injection attacks (e.g., cross-site scripting, SQL injection).
-
Cryptography:
- Plugins should use Artifactory's provided cryptographic libraries and APIs for any encryption, hashing, or digital signature needs.
- Avoid implementing custom cryptographic algorithms.
- Use secure random number generators.
- Store sensitive keys securely.

Build Process Description:
- Developer: Developers write plugin code (Groovy scripts) and commit it to a Git repository.
- Git Repository: The source code for the plugins is stored in a version-controlled Git repository.
- CI/CD Server: A CI/CD server (e.g., Jenkins, GitLab CI) monitors the Git repository for changes. When a change is detected, it triggers a build pipeline.
- SAST Scanner: The build pipeline includes a static application security testing (SAST) step. A SAST tool (e.g., SonarQube, Fortify) scans the plugin code for potential vulnerabilities.
- Dependency Scanner: The build pipeline includes a dependency scanning step. A tool like JFrog Xray or Snyk scans the plugin's dependencies (if any) for known vulnerabilities.
- Artifactory REST API: If the SAST and dependency scans pass, the CI/CD server uses the Artifactory REST API to deploy the plugin to the Artifactory server.
- Artifactory Server: The Artifactory server receives the plugin and stores it in the designated plugin directory.
Security Controls:
- security control: Source Code Management: Using a Git repository provides version control, audit trails, and access control for plugin code.
- security control: CI/CD Pipeline: Automating the build and deployment process ensures consistency and reduces the risk of manual errors.
- security control: SAST Scanning: Static code analysis helps identify vulnerabilities early in the development lifecycle.
- security control: Dependency Scanning: Scanning dependencies helps prevent the use of vulnerable libraries.
- security control: Secure Credentials: The CI/CD server should use secure credential management to store and access the Artifactory API credentials.
- security control: Least Privilege: The CI/CD server should have only the necessary permissions to deploy plugins to Artifactory.
Critical Business Processes:
- Artifact Management: The core process of storing, retrieving, and managing software artifacts.
- Build and Release Pipeline: The process of building and releasing software, which relies on Artifactory for artifact storage and dependency management.
- Software Delivery: The overall process of delivering software to end-users, which depends on the availability and reliability of Artifactory.
Data to Protect:
- Software Artifacts: These are the primary data stored in Artifactory. Their sensitivity varies greatly depending on the nature of the artifacts. They can range from public open-source libraries (low sensitivity) to proprietary source code and compiled binaries (high sensitivity).
- Metadata: Artifactory stores metadata about artifacts, including version information, dependencies, and build details. This metadata can be sensitive, especially if it reveals information about internal development processes or vulnerabilities.
- User Credentials: Artifactory stores user credentials and access tokens. These are highly sensitive and must be protected from unauthorized access.
- Configuration Data: Artifactory's configuration data, including settings related to security, access control, and integrations, is sensitive and must be protected.
- Logs: Artifactory's logs may contain sensitive information, such as user activity, IP addresses, and error messages that could reveal vulnerabilities.
Data Sensitivity Levels:
- High: Proprietary source code, compiled binaries, user credentials, access tokens, sensitive configuration data.
- Medium: Metadata about internal projects, build details, internal documentation.
- Low: Publicly available open-source libraries, publicly available documentation.
Questions:
- What specific APIs are available for plugins to interact with Artifactory? A detailed API documentation reference is needed.
- What are the exact limitations of the Groovy sandbox environment? What system resources are restricted?
- What logging and auditing capabilities are available for plugin activity?
- Are there any existing performance benchmarks for Artifactory plugins?
- What is the recommended approach for handling errors and exceptions within plugins?
