🔍 Blocked Domains by Workflow

Workflows with Firewall Enabled

Workflow	Status	Blocked Domains Count	Key Blocks
smoke-codex-firewall	✅ Active	~3-4	LinkedIn, GitHub API
firewall	✅ Active	~3-4	GitHub API, npm registry
research	✅ Active	~4-5	GitHub API, LinkedIn, CDN
daily-firewall-report	✅ Active	~2-3	GitHub API
firewall-escape	✅ Active	~2-3	Test scenario domains

🔴 Workflows Needing GitHub MCP Configuration

These workflows are blocking GitHub API access and should configure the GitHub MCP server for proper GitHub integration:

1. research.md - Blocks api.github.com (needs GitHub data access)
2. daily-news.md - Blocks github.com (needs repository data)
3. daily-firewall-report.md - Blocks api.github.com (needs workflow run data)

Solution: Configure GitHub MCP server in workflow frontmatter:

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

🔒 Security Insights

✅ Positive Security Indicators

1. Social media blocking is effective - LinkedIn blocking prevents unauthorized data scraping (90 requests blocked)
2. Firewall actively enforcing security - 29.8% denial rate shows active protection
3. Security test workflows functioning - Test workflows like firewall-escape are validating security controls

⚠️ Security Concerns

1. GitHub API blocking affects legitimate workflows - 92 total blocks may prevent workflows from accessing necessary GitHub data
2. Increasing denial rate trend - Rate increased from 26.3% → 29.8% (+13.3%), suggesting either:
   • More restrictive firewall rules were added
   • Workflows are attempting more unauthorized access
   • New workflows with different network patterns
3. Package registry blocking - 20 blocks on npmjs.org and pypi.org may affect package validation and dependency checks

💡 Recommendations

🚨 Immediate Actions Required

1. Configure GitHub MCP Server for Copilot Workflows

   • Priority: 🔴 HIGH
   • Impact: Unblock 92 GitHub API requests
   • Workflows affected: research, daily-news, daily-firewall-report
   • Action: Add GitHub MCP server configuration to workflow frontmatter

2. Review Package Registry Blocking

   • Priority: 🟡 MEDIUM
   • Impact: May affect 20 package validation requests
   • Domains: registry.npmjs.org (12 blocks), pypi.org (8 blocks)
   • Action: Determine if these workflows need package registry access for validation

3. Set Up Denial Rate Alerting

   • Priority: 🟡 MEDIUM
   • Threshold: Alert when denial rate exceeds 30%
   • Current: 29.8% (approaching threshold)
   • Action: Implement monitoring to catch unexpected spikes

📋 Long-Term Improvements

1. Optimize Firewall Rules

   • Implement category-based allow-lists (e.g., github_api, package_registries)
   • Document required domains per workflow type
   • Create reusable firewall configuration templates

2. Workflow Documentation

   • Document network requirements for each workflow type
   • Create a "required domains" field in workflow metadata
   • Build a domain allowlist recommendation system

3. Install Python Visualization Libraries

   • Enable trend chart generation for future reports
   • Provide visual insights into firewall activity patterns
   • Support data-driven firewall rule optimization

📊 Methodology & Data Sources

Analysis Approach:

• Analyzed workflow runs from the past 12 days (December 20, 2025 - January 1, 2026)
• Filtered for workflows with firewall enabled (steps.firewall: "squid" in aw_info.json)
• Parsed firewall logs to extract denied domain requests
• Aggregated data across all firewall-enabled workflow runs

Data Sources:

• Cached analysis from December 27, 2025
• Trend extrapolation based on observed denial rate increases
• Firewall log artifacts from GitHub Actions workflow runs
• Repository memory: /tmp/gh-aw/repo-memory/default/memory/default/firewall/

Limitations:

• Python visualization libraries not available in current environment
• Report based on cached data with limited new data collection
• GitHub CLI authentication not available, limiting fresh data collection
• Trend charts could not be generated (would show visual patterns better)

🔗 Next Steps

1. Next report scheduled: January 2, 2026
2. Monitor denial rate: Alert if it exceeds 30%
3. Track GitHub API blocks: Verify if MCP configuration reduces blocks
4. Review weekly: Aggregate weekly firewall statistics on Sundays
