BUSINESS POSTURE

This project, iced-rs/iced, is a cross-platform GUI library for Rust.

  • Business Priorities and Goals:

    • Provide a user-friendly and productive framework for Rust developers to create graphical applications.
    • Enable the development of cross-platform applications with a single codebase, targeting desktop (Windows, macOS, Linux) and web (via WebAssembly) environments.
    • Offer a performant and efficient GUI solution leveraging Rust's capabilities.
    • Foster a strong community around the library to ensure its long-term sustainability and growth.
    • Encourage adoption of Rust for GUI application development.

  • Business Risks:

    • Adoption risk: Developers may prefer established GUI frameworks or find iced too complex or lacking features compared to alternatives.
    • Security vulnerabilities: Bugs in the library could lead to security issues in applications built with iced.
    • Performance bottlenecks: Inefficient rendering or resource management could negatively impact application performance and user experience.
    • Community dependency: Reliance on community contributions for maintenance and feature development introduces risks if community support wanes.
    • Platform compatibility issues: Maintaining cross-platform compatibility across diverse operating systems and browser environments can be challenging.

SECURITY POSTURE

  • Existing Security Controls:

    • security control: GitHub repository with version control and history. Implemented in: GitHub.
    • security control: Open-source project, allowing for community security reviews. Implemented in: Project nature.
    • security control: Rust's memory safety features mitigate certain classes of vulnerabilities. Implemented in: Rust language.
    • accepted risk: Reliance on external dependencies (crates) which may have their own vulnerabilities. Accepted risk: Dependency management.
    • accepted risk: Potential for vulnerabilities in the core library code. Accepted risk: Software development.

  • Recommended Security Controls:

    • security control: Implement automated dependency scanning to identify vulnerabilities in dependencies.
    • security control: Integrate static analysis security testing (SAST) tools into the CI/CD pipeline to detect potential code-level vulnerabilities.
    • security control: Establish a clear vulnerability reporting and response process.
    • security control: Conduct regular security code reviews, especially for critical components and contributions.
    • security control: Provide security guidelines and best practices for developers using iced to build applications.

  • Security Requirements:

    • Authentication: Not directly applicable to the library itself. Applications built with iced may require authentication, which should be implemented by the application developer using appropriate methods outside of the iced library.
    • Authorization: Not directly applicable to the library itself. Applications built with iced will likely require authorization, which should be implemented by the application developer. iced should provide mechanisms to facilitate secure UI rendering based on application-level authorization decisions.
    • Input Validation: Applications built with iced must perform thorough input validation on all user inputs received through the GUI to prevent injection attacks (e.g., cross-site scripting if rendering web content, command injection if interacting with system commands). iced should provide safe and robust input handling mechanisms to assist developers in implementing input validation.
    • Cryptography: Not directly required by the core iced library. If applications built with iced require cryptography, they should use well-vetted, external cryptography libraries. iced should not implement custom cryptography. If iced provides any utilities related to data handling, ensure they do not inadvertently introduce cryptographic vulnerabilities.

RISK ASSESSMENT

  • Critical Business Processes:

    • Adoption and usage of the iced library by Rust developers.
    • Community contributions and maintenance of the library.
    • Development of secure and performant applications using iced.
    • Distribution of the iced library through crates.io.

  • Data to Protect and Sensitivity:

    • Source code of the iced library: High sensitivity. Integrity and confidentiality are important to prevent malicious modifications and maintain trust.
    • Documentation: Medium sensitivity. Integrity is important to ensure accurate and safe usage guidance.
    • Build artifacts (libraries, binaries): Medium sensitivity. Integrity is crucial to prevent distribution of compromised artifacts.
    • Community contributions: Low to Medium sensitivity. Intellectual property of contributors, but generally intended for public use.

QUESTIONS & ASSUMPTIONS

  • Questions:

    • What are the specific target applications or use cases for iced? (e.g., desktop utilities, embedded systems, web applications).
    • Are there any specific regulatory compliance requirements for applications built with iced? (e.g., GDPR, HIPAA, PCI DSS).
    • What is the expected level of security for applications built with iced? (e.g., basic security, high security for sensitive data).
    • Are there any specific performance requirements or constraints for applications built with iced?

  • Assumptions:

    • The primary goal of iced is to provide a general-purpose, cross-platform GUI library for Rust.
    • Security is a concern for the iced project and applications built with it, but not necessarily the absolute highest priority compared to usability and performance.
    • Applications built with iced will handle user input and potentially sensitive data, requiring attention to input validation and secure data handling at the application level.
    • The iced project relies on community contributions and open-source development practices.
