BUSINESS POSTURE

  • Business Priorities and Goals:
    • Guice aims to simplify the development of Java applications by providing a robust and efficient dependency injection framework.
    • It promotes modularity, testability, and maintainability of codebases, leading to faster development cycles and reduced maintenance costs.
    • By decoupling components, Guice enables developers to focus on business logic rather than dependency management, increasing productivity.
  • Business Risks:
    • Dependency on a third-party library introduces a potential supply chain risk. If vulnerabilities are discovered in Guice, applications using it may become vulnerable.
    • Improper use of dependency injection patterns, although not directly a Guice vulnerability, can lead to complex and less secure application architectures if not implemented correctly.
    • Performance overhead, although generally minimal, could become a concern in performance-critical applications if dependency injection is not used judiciously.

SECURITY POSTURE

  • Existing Security Controls:
    • security control: GitHub repository with standard security features like branch protection and issue tracking. Implemented in: GitHub repository settings.
    • security control: Open source project with community review, increasing the likelihood of identifying and addressing potential vulnerabilities. Implemented in: Open nature of the project and community contributions.
  • Accepted Risks:
    • accepted risk: As a dependency, Guice inherits the risk profile of its development and release process.
    • accepted risk: Potential for vulnerabilities to be discovered in the library after deployment in applications.
  • Recommended Security Controls:
    • security control: Implement automated security scanning (SAST, DAST, dependency scanning) in the Guice build pipeline to detect potential vulnerabilities early.
    • security control: Conduct periodic security audits and code reviews by security experts to identify and mitigate potential security weaknesses.
    • security control: Establish a clear vulnerability disclosure and response process to handle security issues promptly and transparently.
    • security control: Promote secure coding practices within the Guice development team and community.
  • Security Requirements:
    • Authentication: Not directly applicable to Guice as a library. Authentication is the responsibility of the applications that use Guice.
    • Authorization: Not directly applicable to Guice as a library. Authorization is the responsibility of the applications that use Guice.
    • Input Validation: Input validation within Guice primarily concerns the configuration of bindings. Guice should validate binding configurations to prevent unexpected behavior or errors. Implemented in: Guice core logic during injector creation.
    • Cryptography: Cryptography is not a core requirement for Guice itself. If applications using Guice require cryptography, they should implement it independently of Guice.

RISK ASSESSMENT

  • Critical Business Processes:
    • Development of Java applications that rely on dependency injection for modularity, testability, and maintainability.
    • Distribution and consumption of the Guice library by the Java developer community.
  • Data to Protect and Sensitivity:
    • Guice library source code: Sensitive as it represents the intellectual property and core functionality of the project. Confidentiality and integrity are important.
    • Guice build artifacts (JAR files): Integrity and availability are critical to ensure users can reliably and securely use the library.
    • Vulnerability information: Confidentiality is important until a fix is released, then transparency is key for responsible disclosure.

QUESTIONS & ASSUMPTIONS

  • Questions:
    • What is the intended audience and use case for this design document? (Threat modeling for Guice library itself, or for applications using Guice?) - Assuming threat modeling for Guice library itself.
    • Are there specific security compliance requirements that Guice needs to adhere to? - Assuming general best practices for open-source libraries.
    • What is the process for handling security vulnerabilities reported in Guice? - Assuming standard open-source vulnerability disclosure and response process.
  • Assumptions:
    • Guice is intended to be a widely used, general-purpose dependency injection library for Java.
    • Security is a significant concern for the Guice project, given its potential impact on applications that depend on it.
    • The Guice project follows standard open-source development practices, including community involvement and transparency.
    • The target deployment environment for applications using Guice is varied, ranging from cloud to on-premise environments.
