📈 Firewall Activity Trends

Request Patterns Over 7 Days

The analysis shows a concerning upward trend in denial rates:

Metric	Week Start	Current	Change
Denial Rate	26.3%	29.7%	+6.9% ⬆️
Avg Denied/Day	~13	~15	+15% ⬆️
Avg Allowed/Day	~42	~44	+5% ⬆️

Key Observations:

• Denial rate increased from 26.3% to 29.7% over the past week
• Total request volume remained relatively stable
• The increase in denials is primarily from GitHub API and LinkedIn domains
• Firewall is actively blocking more traffic, suggesting either more restrictive rules or increased external access attempts

📊 Note: Trend charts were not generated due to unavailable Python visualization libraries. The analysis is based on aggregated statistics from 9 firewall-enabled workflow runs.

🔍 Security Insights

✅ Positive Security Indicators

1. LinkedIn Blocking Effective

   • Prevents data scraping and rate limiting
   • Firewall correctly blocking social media access
   • Working as intended for research workflows

2. Firewall Actively Protecting

   • 25.2% denial rate shows firewall is working
   • Unauthorized access attempts being blocked
   • Security test workflows functioning correctly

3. Network Segmentation Working

   • Workflows are properly isolated
   • Explicit permission model enforced
   • Default-deny approach preventing leaks

⚠️ Security Concerns

1. GitHub API Blocking Affecting Legitimate Use

   • 92 total GitHub-related requests blocked
   • Workflows designed to use GitHub API are failing
   • Risk: Workflows may fail silently or produce incorrect results

2. Increasing Denial Rate Trend

   • 26.3% → 29.7% (+6.9%) over past week
   • Suggests either more restrictive rules or more access attempts
   • Risk: Legitimate functionality may be broken

3. Package Registry Blocking

   • NPM and PyPI being blocked (37 requests)
   • May affect package validation and dependency resolution
   • Risk: False negatives in package verification workflows

4. Potential for False Positives

   • GitHub CDN domains blocked (avatars, raw content)
   • May prevent legitimate content fetching
   • Risk: Incomplete data or broken workflows

💡 Recommendations

🔴 Immediate Actions Required

1. Configure GitHub MCP Server for Copilot Workflows

   engine: copilot
   tools:
     github:
       mode: remote           # or "local" for Docker
       toolsets: [default]    # Enables repos, issues, pull_requests

   Affected workflows: research.md, daily-news.md, daily-firewall-report.md
   Impact: HIGH - Restores GitHub API access for legitimate workflows
   Timeline: Immediate (today)

2. Review Package Registry Blocking

   • Determine if registry.npmjs.org and pypi.org access is needed
   • If yes, add to allowed domains for validation workflows
   • If no, document the intentional blocking
     Affected workflows: smoke-codex-firewall.md
     Impact: MEDIUM - May affect package validation accuracy
     Timeline: This week

3. Audit High-Denial-Rate Workflows

   • Review workflows with >30% denial rates
   • Verify expected vs actual network access patterns
   • Document required domains per workflow
     Affected workflows: research.md (32.4%)
     Impact: MEDIUM - Ensures workflows function correctly
     Timeline: This week

🟡 Short-Term Improvements (This Month)

4. Optimize Firewall Rules

   • Create workflow-type-based allowlists
   • Reduce false positive blocks
   • Document firewall configuration patterns

5. Set Up Monitoring & Alerting

   • Alert when denial rate exceeds 30%
   • Track denial rate trends
   • Monitor for sudden spikes in blocks

6. Create Domain Allowlist Templates

   • Research workflows: GitHub API, select social media
   • Package workflows: npm, PyPI, GitHub
   • Documentation workflows: GitHub, minimal external

🟢 Long-Term Strategic Actions (This Quarter)

7. Document Required Domains Per Workflow Type

   • Create comprehensive domain requirements
   • Maintain allowlist library
   • Share knowledge across team

8. Implement Firewall Configuration Testing

   • Add tests for firewall config in CI/CD
   • Validate domain allowlists before deployment
   • Catch misconfigurations early

9. Review Denial Trend Quarterly

   • Track denial rate over time
   • Identify patterns and anomalies
   • Adjust firewall strategy accordingly

📌 Workflows Requiring Attention

High Priority (GitHub MCP Configuration Needed)

1. ⚠️ research.md - 32.4% denial rate, needs GitHub API
2. ⚠️ daily-news.md - 28.5% denial rate, needs GitHub API
3. ⚠️ daily-firewall-report.md - 18.2% denial rate, blocked from GitHub

Medium Priority (Review Required)

4. 🔍 smoke-codex-firewall.md - Package registry blocking (intentional?)

Low Priority (Functioning Correctly)

5. ✅ firewall-escape.md - Security test working as expected
6. ✅ firewall.md - Standard firewall workflow

📊 Trend Analysis Summary

Overall Trend: ⬆️ INCREASING DENIAL RATE

• Current Denial Rate: 29.7% (up from 26.3%)
• Change: +3.4 percentage points (+6.9% relative increase)
• Primary Driver: GitHub API and LinkedIn blocking
• Secondary Factor: Package registry access attempts

Interpretation:
The increasing denial rate is primarily driven by workflows attempting to access GitHub APIs without proper MCP configuration. This is a configuration issue, not a security threat. Implementing the GitHub MCP server recommendations will significantly reduce the denial rate while maintaining security.

Expected Outcome After MCP Configuration:

• Denial rate should decrease to ~10-15%
• GitHub API requests will be properly authenticated
• LinkedIn blocking will remain (as intended)
• Package registry access will be evaluated separately
