Secure Coding Standards

The objective of this Secure Coding Standards Plan is to establish a set of guidelines and best practices to ensure the development of secure and robust software within the N3N open-source community.


  1. Security by Design:

    • Incorporate security considerations from the early design phase to identify and mitigate potential vulnerabilities.
  2. Least Privilege Principle:

    • Limit access and permissions to the minimum necessary for each user or system component.
  3. Defense in Depth:

    • Implement multiple layers of security controls to provide redundancy and mitigate the impact of a single security failure.
  4. Fail-Safe Defaults:

    • Configure systems and applications with secure default settings to minimize potential vulnerabilities.
  5. Data Sanitization:

    • Validate and sanitize input data to prevent injection attacks and ensure data integrity.
  6. Secure Authentication:

    • Use strong and adaptive authentication mechanisms. Avoid storing sensitive information, such as passwords, in plaintext.
  7. Secure Authorization:

    • Implement role-based access control (RBAC) and ensure that users have the appropriate permissions based on their roles.
  8. Secure Communication:

    • Use secure communication protocols (e.g., HTTPS) to protect data in transit. Avoid the use of deprecated or insecure protocols.
  9. Error Handling and Logging:

    • Implement proper error handling to provide minimal information to users in case of failures. Log security-relevant events for monitoring.
  10. Code Reviews with Security Focus:

    • Conduct regular code reviews with a focus on security aspects. Encourage peer reviews to catch potential vulnerabilities early.
  11. Secure File Handling:

    • Validate file uploads, avoid insecure file paths, and ensure that file permissions are set appropriately.
  12. Secure Third-Party Components:

    • Regularly update and patch third-party libraries and components. Validate the security posture of dependencies.
  13. Buffer Overflow Protection:

    • Implement bounds checking to prevent buffer overflow vulnerabilities.
  14. Continuous Security Training:

    • Provide ongoing security training for developers to keep them informed about emerging threats and best practices.
  15. Security Testing:

    • Integrate automated and manual security testing into the development lifecycle, including static code analysis and dynamic application security testing (DAST).

Enforcement and Review

By adhering to these coding standards, N3N aims to create a secure and resilient software environment. Thank you for your commitment to secure coding practices!
