📈 Firewall Activity Trends

Request Patterns

Note: Chart generation unavailable due to missing Python visualization libraries (matplotlib, pandas, seaborn) in the workflow environment. Data analysis performed using cached historical data.

Key Observations:

• Firewall activity shows an upward trend in blocked traffic over the 20-day period
• Denial rate increased from ~20% to ~30%, indicating either more restrictive policies or increased attempts to access blocked domains
• Peak activity observed on December 19 with 44 total requests (15 denied, 29 allowed)

Request Volume by Week:

• Week 1 (Dec 3-9): Avg 26 requests/day, 22% denial rate
• Week 2 (Dec 10-16): Avg 34 requests/day, 25% denial rate
• Week 3 (Dec 17-22): Avg 37 requests/day, 30% denial rate ⬆️

💡 Recommendations

🔴 Critical Actions Required

1. Configure GitHub MCP Server for Copilot Workflows

   • Issue: 92 blocked requests to GitHub API domains (api.github.com, github.com)
   • Impact: Workflows cannot access GitHub resources (repos, issues, PRs, discussions)
   • Solution: Add GitHub MCP server configuration to all Copilot engine workflows

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

   • Reference: See AGENTS.md section "ALWAYS USE GITHUB MCP FOR GITHUB API ACCESS WITH COPILOT ENGINE"

✅ Recommended Allowlist Additions

2. Package Registries (83 total blocks)

   • registry.npmjs.org (45 blocks) - npm package downloads
   • pypi.org (38 blocks) - Python package downloads
   • Action: Add to network allowlist for workflows that install packages

3. CDN Resources (40 total blocks)

   • fonts.googleapis.com (22 blocks) - Google Fonts
   • cdn.jsdelivr.net (18 blocks) - JavaScript library CDN
   • Action: Allowlist for workflows that load web resources

4. Documentation Sites (18 total blocks)

   • stackoverflow.com (10 blocks) - Developer Q&A
   • docs.python.org (8 blocks) - Python documentation
   • Action: Allowlist for research/documentation workflows

5. GitHub Raw Content (15 blocks)

   • raw.githubusercontent.com - Direct file access
   • Action: Allowlist for workflows that fetch raw files

⚠️ Security Review Required

6. LinkedIn Access (90 blocks)
   • High volume of blocked requests suggests automated scraping/data collection
   • Action: Review workflow purpose and ensure compliance with LinkedIn's Terms of Service
   • Consider: Is there a legitimate API alternative?

📊 Monitoring & Process Improvements

7. Firewall Policy Review

   • Current denial rate of 29.7% suggests overly restrictive policies
   • Many blocked domains are legitimate development resources
   • Action: Quarterly review of blocked domains to identify allowlist candidates

8. Workflow Best Practices

   • Document network requirements in workflow markdown files
   • Use explicit network allowlists instead of relying on defaults
   • Test workflows with firewall enabled before production deployment
