Security Audit: Agent Capability Negotiation and Binding Protocol (ACNBP) Platform

Audit.md

Security and Implementation Review Checklist

• Environment Configuration

  • The .env file should be included in .gitignore to prevent committing sensitive information like API keys. This is mentioned in the README.md, but it must be enforced.

• Database Files

  • The agent_registry.db file is skipped in commits, but should be checked to ensure it doesn't contain sensitive information or credentials.

• Key Management

  • src/app/api/secure-binding/ca/route.ts stores CA keys in memory. Not secure for production. Use a secure key management service.
  • src/app/api/secure-binding/agent-keys/route.ts stores agent keys in memory. Use a secure key management service.

• Certificate Handling

  • src/app/api/secure-binding/issue-certificate/route.ts issues certificates without validating agent identity. Add proper identity checks.
  • src/app/api/secure-binding/verify-message/route.ts verifies messages but lacks certificate revocation checks. Implement revocation mechanism.

• Agent Status Management

  • src/app/api/agent-registry/renew/route.ts and revoke/route.ts do not update agent status in real-time. Ensure immediate updates post-renewal/revocation.

• SQL Injection Prevention

  • The following files are vulnerable and must use parameterized queries:
    • src/app/api/agent-registry/route.ts
    • src/app/api/ans/resolve/route.ts
    • src/app/api/negotiate-capabilities/route.ts
    • src/app/api/secure-binding/sign-message/route.ts
    • src/app/api/secure-binding/verify-message/route.ts

• Sensitive Logging

  • src/app/secure-binding/page.tsx logs sensitive data (keys, certificates). This should be removed or masked.

• Race Condition Mitigation

  • Implement locking mechanisms in:
    • src/app/api/agent-registry/route.ts
    • renew/route.ts
    • revoke/route.ts
    • ans/resolve/route.ts
    • negotiate-capabilities/route.ts
    • secure-binding/sign-message/route.ts
    • secure-binding/verify-message/route.ts

• Denial-of-Service (DoS) Protection

  • Implement rate limiting in:
    • src/app/api/agent-registry/route.ts
    • renew/route.ts
    • revoke/route.ts
    • ans/resolve/route.ts
    • negotiate-capabilities/route.ts
    • secure-binding/sign-message/route.ts
    • secure-binding/verify-message/route.ts

Security & Code Review Suggestions

Current Issues

• agent_deactivation_api.py and agent_registration_api.py lack authentication and authorization checks.
• agent_registration_db.py does not sanitize inputs, making it vulnerable to SQL injection.
• agent_renewal_api.py and agent_status_api.py do not validate input parameters adequately.
• authentication_authorization.py provides JWT validation but is not integrated into main APIs.
• credential_hygiene.py shows credential rotation techniques but is unused in production code.
• discovery_tool.py validates certificates but fails to check for expiration or revocation.
• Test files (test_registration_api.py, test_renewal_api.py) do not cover edge cases or security concerns.

Proposed Enhancements

• Integrate authentication_authorization.py into all major APIs (agent_deactivation_api.py, agent_registration_api.py, agent_renewal_api.py, agent_status_api.py) for JWT-based authentication and authorization.
• Update agent_registration_db.py to sanitize inputs using parameterized queries to mitigate SQL injection.
• Enhance discovery_tool.py to check for expired/revoked certificates and add error logging.
• Expand test coverage in test_registration_api.py, test_renewal_api.py, test_deactivation_api.py, and test_status_api.py to include edge cases and security vulnerability scenarios.
• Integrate credential_hygiene.py into the main codebase to enable active credential rotation and auditing.

Suggested Questions for Review

• How are the certificates managed and rotated in the system?
• What are the potential security risks in agent_registration_db.py?
• How is the integrity of JSON schemas validated before processing?
• Are there structured logging mechanisms to track API request metadata?
• What improvements could be made to strengthen certificate validation?
• What secure coding practices are followed when handling sensitive data?

Timeline

• Review and integrate changes over a two-week sprint.
• Prioritize integration of authentication_authorization.py and input sanitization first.
• Follow with enhanced certificate validation and test suite expansion.
