Mitigation Strategy: Implement a Strict Extension Vetting Process

  • Mitigation Strategy: Implement a Strict Extension Vetting Process
    • Description:
      • Step 1: Establish a central repository or document listing approved Brackets extensions for team use.
      • Step 2: Define clear criteria for extension approval, including:
        • Source code availability and reviewability.
        • Permissions requested by the extension within Brackets.
        • Developer reputation and history within the Brackets extension ecosystem.
        • Community reviews and ratings specifically related to Brackets extensions.
        • Active maintenance status and update frequency within the Brackets extension registry.
      • Step 3: Assign a designated team member or security team to review extension requests against the defined criteria, focusing on Brackets-specific risks.
      • Step 4: Document the review process and approval decisions for each extension within the context of Brackets usage.
      • Step 5: Communicate the list of approved extensions to the development team and enforce its use within Brackets.
      • Step 6: Regularly review and update the approved extension list, removing or deprecating extensions as needed within the Brackets environment.
    • List of Threats Mitigated:
      • Malicious Extension Installation within Brackets - Severity: High (Potential for code execution within Brackets, data theft from Brackets projects, Brackets application compromise)
      • Vulnerable Extension Exploitation within Brackets - Severity: High (Potential for code execution within Brackets, data theft from Brackets projects, Brackets application compromise)

Mitigation Strategy: Principle of Least Privilege for Brackets Extensions

  • Mitigation Strategy: Principle of Least Privilege for Brackets Extensions
    • Description:
      • Step 1: When evaluating extensions for Brackets, prioritize those that request minimal permissions within the Brackets environment.
      • Step 2: Carefully review the permissions requested by each Brackets extension before installation, focusing on what access they request within Brackets and to Brackets projects.
      • Step 3: If multiple Brackets extensions offer similar functionality, choose the one with the least demanding permission set within Brackets.
      • Step 4: Avoid Brackets extensions that request broad permissions like "full file system access" or "network access" unless absolutely necessary for their Brackets-related functionality and justified by their Brackets use case.
      • Step 5: If possible, configure Brackets extension settings to further restrict their access or capabilities within the Brackets editor.
