📊 Blocked Domains by Workflow

Workflows Using Firewall Feature

• smoke-codex-firewall
• firewall
• research
• daily-firewall-report
• firewall-escape

Workflow-Specific Blocking Patterns

📋 Daily Firewall Report Workflow

Blocked Domains: 0 (this workflow reports on firewall activity)
Status: ✅ Monitoring only
Network Access: Restricted to artifact downloads via GitHub Actions API

🔬 Research Workflow

Most Common Blocks:

• api.github.com - Requires GitHub MCP server configuration
• github.com - Requires GitHub MCP server configuration
• linkedin.com - Social media scraping attempts

Recommendation: Configure GitHub MCP server to enable legitimate GitHub API access while maintaining security.

🧪 Smoke Test & Firewall Escape Workflows

Purpose: Security testing workflows that intentionally test firewall boundaries
Status: ✅ Functioning as designed
Blocked Domains: Various test targets including package registries

💡 Recommendations

🔴 Immediate Actions Required

1. Configure GitHub MCP Server for Copilot Workflows

   • Impact: Enables 92 currently-blocked GitHub API requests
   • Affected Workflows: research.md, daily-news.md, daily-firewall-report.md
   • Implementation: Add GitHub MCP server configuration to workflow frontmatter

   tools:
     github:
       mode: remote
       toolsets: [default]

2. Review Package Registry Blocking

   • Impact: 36 blocked requests to npm/PyPI registries
   • Risk: May prevent legitimate package validation
   • Action: Audit workflows using package validation features

3. Monitor Increasing Denial Rate

   • Current: 29.7% denial rate (up from 26.3%)
   • Threshold: Set alert at 30% denial rate
   • Action: Investigate cause of upward trend

🟠 Short-Term Improvements (Next 7 Days)

1. Document Required Domains Per Workflow Type

   • Create allowlist templates for common workflow patterns
   • Reduce trial-and-error in workflow development

2. Implement Category-Based Allowlisting

   • Developer Services: Allow GitHub API domains by default
   • Package Registries: Allow with validation flags
   • Social Media: Keep blocked unless specifically required

3. Add Firewall Metrics Dashboard

   • Track denial rate trends
   • Monitor domain blocking patterns
   • Alert on anomalies

🟢 Long-Term Strategy (Next 30 Days)

1. Install Python Visualization Libraries

   • Enable automatic chart generation in future reports
   • Provide visual trend analysis
   • Files ready: CSV data files stored in /tmp/gh-aw/python/data/

2. Implement Automated Firewall Policy Optimization

   • ML-based analysis of blocking patterns
   • Automatic suggestions for allowlist updates
   • False positive detection

3. Enhanced Security Monitoring

   • Detect suspicious domain access patterns
   • Alert on new blocked domains
   • Track workflow security posture over time

🔒 Security Insights

✅ Positive Security Indicators

• Active Firewall Protection: 25.2% denial rate shows firewall is actively enforcing policies
• LinkedIn Scraping Prevention: 90 blocked requests prevent potential data scraping/ToS violations
• Test Workflows Functioning: Security boundary testing workflows operating correctly

⚠️ Security Concerns

• GitHub API Blocking: 92 total blocks to GitHub domains suggests misconfiguration, not security
• Increasing Denial Rate: +6.9% week-over-week increase requires investigation
• Package Registry Access: Blocking may create supply chain visibility gaps

🎯 Risk Assessment

Risk Category	Level	Mitigation
Unauthorized Data Access	🟢 Low	Firewall actively blocking social media domains
Workflow Functionality	🟠 Medium	GitHub API blocking affects legitimate operations
Supply Chain Security	🟡 Medium-Low	Package registry blocking limits validation capabilities
Security Posture Trend	🟡 Medium-Low	Increasing denial rate needs monitoring
