BUSINESS POSTURE

  • Business Priorities and Goals:

    • The primary goal of the android-iconics project is to provide Android developers with a convenient and efficient way to integrate icon fonts into their applications.
    • This aims to improve the visual appeal and user experience of Android applications by simplifying the use of vector icons.
    • The project prioritizes ease of use, flexibility in icon font selection, and seamless integration into the Android development workflow.

  • Business Risks:

    • Supply Chain Risks: As a library consumed by other projects, any compromise in the android-iconics library could propagate to dependent applications, posing a supply chain risk. This includes risks related to compromised dependencies or malicious code injection into the library itself.
    • Availability Risks: If the library becomes unavailable or unusable due to unforeseen issues (e.g., repository compromise, critical bugs), developers relying on it may face disruptions in their development process and application updates.
    • Reputational Risk: Security vulnerabilities or malicious code found in the library could damage the reputation of the project and potentially impact the trust of developers using it.
    • Maintainability Risk: Lack of active maintenance and updates could lead to the library becoming outdated, incompatible with newer Android versions, or vulnerable to newly discovered security threats.

SECURITY POSTURE

  • Existing Security Controls:

    • security control: Open Source Code Review - The project is hosted on GitHub and is open source, allowing for community review of the code. This can help identify potential security vulnerabilities and improve code quality. Implemented: GitHub Repository.
    • security control: Version Control - The project uses Git for version control, providing traceability of changes and the ability to revert to previous versions if necessary. Implemented: GitHub Repository.
    • security control: Dependency Management - The project uses Gradle for dependency management, allowing for controlled inclusion of external libraries. Implemented: build.gradle files.

  • Accepted Risks:

    • accepted risk: Reliance on Third-Party Icon Fonts - The library depends on external icon font files, which are not directly controlled by the project. The security and licensing of these external fonts are implicitly accepted risks.
    • accepted risk: Open Source Vulnerabilities - As an open-source project, vulnerabilities might be discovered and publicly disclosed before a fix is available. The risk of exploitation during this window is implicitly accepted.

  • Recommended Security Controls:

    • security control: Dependency Scanning - Implement automated dependency scanning to identify known vulnerabilities in the project's dependencies.
    • security control: Static Application Security Testing (SAST) - Integrate SAST tools into the build process to automatically scan the codebase for potential security vulnerabilities.
    • security control: Software Bill of Materials (SBOM) Generation - Generate SBOM for each release to provide transparency into the components included in the library, aiding in vulnerability management for consumers.
    • security control: Code Signing - Sign the released artifacts (e.g., AAR files) to ensure integrity and authenticity, allowing consumers to verify that the library has not been tampered with.
    • security control: Regular Security Audits - Conduct periodic security audits of the codebase and build process to proactively identify and address potential security weaknesses.

  • Security Requirements:

    • Authentication: Not applicable - The library itself does not handle user authentication as it is a client-side library.
    • Authorization: Not applicable - The library does not enforce authorization as it operates within the context of the application using it.
    • Input Validation:
      • The library should validate any input it receives, such as icon names or font paths, to prevent unexpected behavior or potential vulnerabilities.
      • Input validation should be implemented to ensure that only expected and safe values are processed.
      • Validation should occur at the point of input to prevent issues from propagating through the library.
    • Cryptography: Not applicable - The library is not expected to perform cryptographic operations. If cryptography were to be introduced, it would require careful design and implementation to ensure security.

RISK ASSESSMENT

  • Critical Business Processes:

    • Distribution of the android-iconics library to Android developers is the most critical business process. Ensuring the library is available, functional, and secure is paramount for its continued adoption and use.
    • Maintaining the integrity and trustworthiness of the library is also critical, as compromised library versions could negatively impact applications that depend on it.

  • Data to Protect and Sensitivity:

    • Library Source Code: Sensitivity - Publicly available, but integrity and confidentiality during development are important to prevent unauthorized modifications before release.
    • Build Artifacts (AAR files): Sensitivity - Publicly available, but integrity and authenticity are critical to ensure developers are using legitimate and untampered versions of the library.
    • Build Environment and CI/CD Pipeline Configurations: Sensitivity - Confidential. These configurations contain sensitive information like build processes, secrets, and access credentials. Compromise could lead to supply chain attacks.
    • Developer Credentials and Access Keys: Sensitivity - Confidential. Necessary for accessing and managing the repository, CI/CD pipeline, and publishing artifacts. Compromise could lead to unauthorized modifications and malicious releases.
