User Tooling

Users of BEAM languages, such as Erlang and Elixir, have access to several tools to help them identify if their dependencies are vulnerable to security issues. These tools enable users to proactively monitor their dependencies for known vulnerabilities, ensuring the integrity and security of their applications. Here’s an overview of the tooling available:

1. Hex Audit (mix hex.audit):
   • Hex.pm, the package manager for the ecosystem, can retire packages for security reasons. The mix hex.audit command allows users to check if any of their dependencies have been retired due to security concerns.
   • This tool can be integrated into continuous integration (CI) pipelines to automatically check dependencies for retirement status, providing early warning of potential security risks.
2. MixAudit (mix deps.audit):
   • MixAudit is a tool that checks if any dependencies in an Elixir project are part of disclosed vulnerabilities. It leverages the curated vulnerability reports in the GitHub Vulnerability Database.
   • By running mix deps.audit, users can quickly identify if any of their project dependencies have known vulnerabilities, allowing them to take appropriate action to mitigate risks.
   • Similar to mix hex.audit, MixAudit can be incorporated into CI workflows to automate vulnerability checks and ensure continuous security monitoring.
3. Commercial Tools (e.g., Paraxial.io):
   • Commercial solutions like Paraxial.io offer advanced features for monitoring dependency vulnerabilities at runtime.
   • These tools provide real-time reporting and alerts when a dependency becomes vulnerable, allowing users to react promptly to emerging security threats.
   • Leveraging curated vulnerability reports from sources like the GitHub Vulnerability Database, these tools offer comprehensive coverage and accuracy in identifying security issues.

By utilizing these tools, users of BEAM languages can stay vigilant against potential security vulnerabilities in their dependencies. Whether through retirement status checks, static analysis of disclosed vulnerabilities, or real-time monitoring at runtime, these tools empower developers to make informed decisions and take proactive measures to secure their applications. Integrating these tools into CI pipelines ensures that security checks are performed consistently and automatically, reducing the risk of exposure to known vulnerabilities throughout the development lifecycle.

The retirement of packages in Hex and the proper disclosure of vulnerabilities in GitHub are essential for users of dependency vulnerability monitoring tools to effectively identify and mitigate security risks. When a package is retired in Hex due to security concerns, it signifies that the package is no longer considered safe for use, and users should transition away from it to maintain the security of their applications. Tools like mix hex.audit rely on the retirement status provided by Hex to flag dependencies that may pose security risks. Without accurate retirement information, users may unknowingly continue to use deprecated or vulnerable packages, leaving their applications susceptible to exploitation.

Similarly, the proper disclosure of vulnerabilities in the GitHub Vulnerability Database is crucial for tools like MixAudit to identify known security issues in project dependencies. When vulnerabilities are disclosed and documented in the GitHub database, tools can cross-reference dependencies against these reports to determine if any components are affected. This ensures that users are promptly notified of vulnerabilities in their dependencies, enabling them to take immediate action to update or replace vulnerable packages. However, without comprehensive and up-to-date vulnerability disclosures, users may miss critical security alerts, leaving their applications exposed to potential attacks. Therefore, transparent and timely disclosure of vulnerabilities in publicly accessible databases is fundamental for maintaining the effectiveness of dependency vulnerability monitoring tools and safeguarding the integrity of BEAM language applications.
