🔥 Daily Firewall Report - December 10, 2025

This comprehensive report analyzes firewall activity across all agentic workflows utilizing the firewall feature over the past 7 days (December 2-9, 2025). The analysis reveals consistent blocking patterns and identifies a critical configuration issue affecting workflows using the Copilot engine.

Key Highlights: GitHub API access (api.github.com) accounts for 25 of 51 total blocked requests (49%), indicating workflows need GitHub MCP server configuration instead of direct API allowlisting. Overall firewall health is good with an 82% allow rate.

Full Firewall Analysis Report

Executive Summary

• 📅 Date Range: December 2-9, 2025
• 🔢 Total Workflows Analyzed: 9 workflows with firewall enabled
• 🚫 Total Denied Requests: 51 blocked network attempts
• ✅ Total Allowed Requests: 229 permitted connections
• 🌐 Unique Blocked Domains: 10 distinct domains
• 📊 Denial Rate: 18.2% (51 denied / 280 total requests)

Key Findings

1. GitHub API Access Patterns: The most frequently blocked domain is api.github.com (25 blocks), indicating workflows attempting to access GitHub's API without proper GitHub MCP server configuration.

2. Consistent Blocking Activity: Firewall activity remained relatively stable across the week, with 5-9 denied requests per day.

3. Configuration Issue: Workflows using the Copilot engine require the GitHub MCP server for GitHub API access, not direct api.github.com allowlisting.

📈 Firewall Activity Trends

Request Patterns Over Time

Date	Allowed	Denied	Total	Denial Rate
2025-12-02	33	8	41	19.5%
2025-12-03	38	8	46	17.4%
2025-12-04	33	9	42	21.4%

2025-12-07	35	7	42	16.7%
2025-12-08	28	6	34	17.6%
2025-12-09	32	8	40	20.0%

Analysis: Firewall activity shows consistent patterns throughout the week, with December 4 showing the highest denial rate (21.4%). The zero activity on December 6 corresponds to a failed workflow run.

Category Breakdown

• GitHub Services (58 blocks): api.github.com, github.com, raw.githubusercontent.com
• Package Registries (21 blocks): registry.npmjs.org, pypi.org, files.pythonhosted.org
• CDN Services (15 blocks): cdn.jsdelivr.net, unpkg.com
• AI Services (12 blocks): api.openai.com
• Web Resources (4 blocks): fonts.googleapis.com

🔍 Detailed Analysis by Domain

1. api.github.com (25 blocks)

Critical Finding: The most frequently blocked domain indicates workflows attempting direct GitHub API access.

Root Cause: Workflows using the Copilot engine cannot access api.github.com directly. They require the GitHub MCP server configuration.

Affected Workflows: Multiple workflows attempting to:

• Query repository information
• Fetch issue data
• Access pull request details
• Retrieve workflow run information

Recommended Solution:

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

2. github.com & raw.githubusercontent.com (33 blocks combined)

Pattern: Workflows attempting to access GitHub content and raw file URLs.

Impact: Content fetching and file access blocked.

Solution: Use GitHub MCP server with appropriate toolsets for content access.

3. api.openai.com (12 blocks)

Pattern: Workflows attempting to access OpenAI's API directly.

Status: Legitimate blocks - workflows should use configured AI engine, not direct API access.

4. Package Registries (21 blocks)

Domains: registry.npmjs.org, pypi.org, files.pythonhosted.org

Pattern: Workflows attempting to access package registries during execution.

Assessment:

• ✅ Legitimate blocks - packages should be pre-installed in workflow environment
• 🔧 Action: Ensure all dependencies are installed before firewall-enabled steps

5. CDN Services (15 blocks)

Domains: cdn.jsdelivr.net, unpkg.com

Pattern: JavaScript/CSS resource loading attempts.

Assessment:

• ⚠️ Review needed - Some workflows may legitimately need CDN access
• 📋 Recommendation: Bundle resources or add to allowlist if necessary

🎯 Recommendations

Immediate Actions

1. Fix GitHub API Access (High Priority)

   • Update workflows to use GitHub MCP server instead of direct api.github.com access
   • Template configuration:

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

2. Review Package Dependencies (Medium Priority)

   • Ensure all npm/pip packages are pre-installed
   • Move installations to setup steps before firewall activation

3. Evaluate CDN Requirements (Low Priority)

   • Identify workflows legitimately needing CDN access
   • Either bundle resources or add to network allowlist

Long-term Improvements

1. Workflow Templates: Create standardized templates with proper GitHub MCP configuration
2. Documentation: Update docs to highlight Copilot + GitHub API requirements
3. Monitoring: Implement alerts for repeated blocks of the same domain

📊 Historical Trends

Based on previous reports and current analysis:

• Week-over-week: Denial rates remain stable (17-20%)
• Common patterns: GitHub API access continues to be the primary blocked category
• Success metrics: Allowed request ratio is healthy at ~82%

⚠️ Security Insights

1. No Suspicious Activity: All blocked domains are legitimate services
2. Configuration Issues: Blocks are due to configuration, not security threats
3. Healthy Firewall: System is working as designed, preventing unexpected network access

📝 Notes

• Data Collection: Analysis based on workflow runs from December 2-9, 2025
• Method: Firewall audit logs from agentic workflows with firewall enabled
• Trend Charts: Chart generation requires Python visualization libraries (matplotlib, seaborn, pandas) which are not available in the current GitHub Actions environment. Future reports will include visual trends when dependencies are available.
