CNI Lightweight Threat Assessment

Introduction

This document presents a lightweight threat assessment for the Container Network Interface (CNI) project, aiming to identify potential security threats and propose mitigation strategies.

Threat Analysis

Potential Unauthorized Access to Network Configurations

• Category: Repudiation
• Given that CNI is an administrative tool used to manage container networking, malicious or abusive actions that CNI is directed to perform should be traceable.
• Possible Mitigation Strategies:
  • Mandate logging mechanisms.
  • Implement auditing of access logs.

Misconfiguration of Networks Leading to Vulnerabilities

• Category: Denial of Service, Tampering
• Certain configurations may lead to unexpected denial of service or tampering due to a plugin’s precedence rules or if a configuration is invalid.
• Possible Mitigation Strategies:
  • Provide clear documentation on secure configuration practices.
  • Implement configuration validation tools.

Conclusion

Ongoing evaluation and updates to this assessment are necessary to adapt to evolving security threats in the CNI project.
