Workflows Using Firewall

1. Firewall Test Agent (.github/workflows/firewall.lock.yml)

   • Runs: 4
   • Purpose: Testing firewall blocking of unauthorized domains
   • Test domain: example.com
   • Status: All successful

2. Dev Firewall (.github/workflows/dev.firewall.lock.yml)

   • Runs: 6
   • Purpose: Development and testing of firewall features
   • Status: All successful (1 failure during early development)

🚫 Blocked Domains Analysis

Summary of Blocked Traffic

Based on the test runs, the firewall successfully blocked access to:

Domain	Block Count	Category	Notes
example.com	8+	Test Domain	Intentionally blocked for firewall validation
httpbin.org	~2	Testing Service	Blocked during network permission tests
Invalid domains	1	DNS Errors	Malformed domain requests

Domain Blocking Patterns

Primary Use Case: Testing and validating network permission enforcement

The most frequently blocked domain is example.com, which serves as the primary test target for firewall functionality. According to the workflow configuration, this domain is intentionally:

• NOT included in the allowed domains list
• Used to verify firewall blocking capability
• Part of automated testing to ensure network restrictions work correctly

📈 Timeline of Firewall Activity

October 24, 2025 (Peak Testing Day)

• 6 workflow runs with firewall enabled
• Multiple iterations testing firewall log parsing and bug fixes

  • Engine switch from Claude to Copilot
  • Log parser fixes
  • Permission handling improvements

October 25, 2025

• 1 run: Dev Firewall testing firewall log parser rejecting invalid domains

October 27, 2025

🔍 Detailed Run Analysis

Recent Successful Runs

1. §18952668194 - October 30

   • Workflow: Firewall Test Agent
   • Status: ✅ Success
   • Duration: ~1.5 minutes
   • Note: Testing after action pins refactoring

2. §18881979253 - October 28

   • Workflow: Firewall Test Agent

   • Status: ✅ Success
   • Duration: ~2 minutes
   • Note: Testing with persist-credentials: false enhancement

Artifacts Generated

Each firewall-enabled run produces:

• Firewall logs (squid-logs-* artifacts)
• Agent outputs (execution details)
• Workflow information (aw_info.json)
• Agent stdio logs (debugging information)

💡 Key Insights

1. Firewall Feature Status

• ✅ Stable implementation: 100% success rate in recent runs
• ✅ Active development: Multiple enhancements and bug fixes
• ✅ Network permissions working: Successfully blocking unauthorized domains
• ✅ Logging functional: Squid logs being captured and uploaded

2. Testing Methodology

• Uses example.com as intentional block target
• Validates that agent cannot access blocked domains
• Ensures firewall logs are properly captured
• Tests both Copilot and Claude engines with firewall

3. Security Enhancements

Recent commits show focus on:

• Network permission enforcement
• Firewall log parsing improvements
• Credential security (persist-credentials: false)
• Error handling for invalid domains

🎯 Recommendations

For Legitimate Service Allowlisting

Currently, the firewall is in test mode with very restrictive permissions. As this moves to production:

1. Review allowed domains list: Ensure necessary infrastructure domains are permitted

   • GitHub APIs
   • Package registries (npm, PyPI)
   • CI/CD services
   • Documentation sites

2. Monitor denied requests: Track legitimate requests being blocked

   • Review firewall logs for production workflows
   • Identify patterns of legitimate service access
   • Adjust allowlist accordingly

3. Workflow-specific permissions: Consider different permission levels for different workflow types

   • Development workflows: More permissive
   • Security-sensitive workflows: Strict restrictions
   • Public-facing workflows: Balanced approach

For Network Permission Improvements

1. Document allowed domains: Maintain clear documentation of why each domain is allowed
2. Categorize domains: Group by purpose (infrastructure, external APIs, testing)
3. Regular audits: Review firewall logs monthly to identify trends
4. Emergency bypass: Have documented process for urgent allowlist updates

Workflows Needing Attention

Based on the analysis, no workflows are experiencing unexpected blocking. All denied requests are intentional test cases validating firewall functionality.

🔐 Security Observations

Positive Security Indicators

1. Firewall is functional: Successfully blocking unauthorized access
2. Logging enabled: All firewall activity is logged for audit
3. Test-driven approach: Thorough testing before production use
4. Credential protection: Recent enhancement to disable credential persistence

Areas for Continued Vigilance

1. Monitor allowlist growth: Ensure added domains are necessary
2. Review logs regularly: Check for suspicious access patterns
3. Document exceptions: Clearly justify any permissive rules
4. Test coverage: Maintain comprehensive firewall test suite

🚀 Future Enhancements

Based on current testing patterns, consider:

1. Automated allowlist management: Tool to propose domain additions
2. Per-workflow permissions: Granular control based on workflow needs
3. Firewall analytics dashboard: Visual trends of blocked/allowed traffic
4. Alert system: Notify on unusual blocking patterns
5. Self-service allowlisting: Controlled process for workflow authors
