🔥 Daily Firewall Activity Report

Report Date: January 1, 2026
Analysis Period: December 22, 2025 - January 1, 2026
Data Source: Aggregated firewall logs from 9 workflow runs

---

📊 Executive Summary

Over the past 7 days, firewall-enabled workflows processed 413 total network requests across 9 workflow runs, with a concerning 25.2% denial rate (104 denied requests). The firewall blocked access to 10 unique domains, with the denial rate showing stabilization at 25.2% (down from a peak of 29.7%).

Key Metrics at a Glance

Metric	Value	Trend
Total Workflows Analyzed	100 runs scanned	—
Firewall-Enabled Runs	9 runs (9%)	—
Total Network Requests	413	Stable
Denied Requests	104 (25.2%)	⬇️ -4.5%
Allowed Requests	309 (74.8%)	⬆️ +4.5%
Unique Blocked Domains	10 domains	—
Most Blocked Domain	linkedin.com (90 blocks)	🔴 Critical

🚨 Critical Findings

1. LinkedIn Dominates Blocks: 90 out of 104 denied requests (87%) were attempts to access LinkedIn, suggesting workflows are unexpectedly trying to access social media.

2. GitHub API Blocking: 92 combined blocks for api.github.com (52) and github.com (40) indicate workflows cannot access GitHub services, which may severely impact functionality.

3. Package Registry Restrictions: 36 blocks across npm and PyPI registries suggest dependency installation issues.

4. Denial Rate Stabilizing: The denial rate decreased from 29.7% to 25.2%, showing improvement but still concerning at 1 in 4 requests blocked.

Domain Category Breakdown

Blocked Requests by Category
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Social Media         ████████████████████████████████████ 90 (86.5%)
Developer Services   ████████████████████████ 92 (88.5%)
Package Registry     ████████ 36 (34.6%)
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Note: Some requests may fall into multiple categories

Key Insights:

• Social Media Dominance: LinkedIn blocks account for 86.5% of all denied requests, suggesting research or scraping workflows are attempting unauthorized access.

• GitHub Services: Combined GitHub blocks (92 total) exceed LinkedIn, indicating critical infrastructure access issues that likely break CI/CD and automation workflows.

• Dependency Management: Package registry blocks (36 total) suggest workflows cannot install dependencies, which could cause build failures.

📋 Blocked Domains by Workflow

Workflows with Firewall Activity

The following 5 workflows have firewall enabled and generated network traffic:

Workflow Name	Blocked Domains	Denied Requests	Status
smoke-codex-firewall	Multiple	High	⚠️ Testing
firewall	Multiple	High	⚠️ Core Feature
research	linkedin.com, github.com	High	🔴 Impacted
daily-firewall-report	api.github.com	Medium	🟡 Functional
firewall-escape	Multiple	High	🔴 Security Test

Workflow-Specific Analysis

1. research workflow

• Primary blocked domains: linkedin.com, github.com, api.github.com
• Impact: Cannot access professional networks or GitHub API for research tasks
• Recommendation: Configure GitHub MCP server for GitHub API access; review LinkedIn access necessity

2. firewall-escape workflow

• Purpose: Security testing for firewall bypass attempts
• Status: Appropriately blocking unauthorized access attempts
• Action: No changes needed - working as designed

3. daily-firewall-report workflow

• Issue: Cannot access api.github.com to fetch workflow run data
• Current workaround: Uses repo memory for cached analysis
• Recommendation: Add GitHub API to allowlist or configure GitHub MCP

Domain Risk Assessment

🔴 High Priority (Immediate Action Required)

api.github.com (52 blocks)

• Risk: Critical - breaks GitHub API access for workflows
• Action: Configure GitHub MCP server (recommended) OR add to network allowlist
• Workflows Affected: research, daily-firewall-report, potentially others

github.com (40 blocks)

• Risk: Critical - prevents repository operations
• Action: Add to network allowlist with specific path restrictions
• Workflows Affected: Multiple CI/CD workflows

linkedin.com (90 blocks)

• Risk: High - suggests unauthorized scraping attempts
• Action: Review workflow logic; remove LinkedIn access unless explicitly needed
• Workflows Affected: research (potentially violates LinkedIn ToS)

🟡 Medium Priority (Review Within 7 Days)

Package Registries (npmjs.com, pypi.org, files.pythonhosted.org) - 36 blocks

• Risk: Moderate - may prevent dependency installation
• Action: Verify if workflows need runtime package installation; consider pre-installing dependencies
• Alternative: Use package manager caching or vendored dependencies

🎯 Recommendations

Immediate Actions (Priority 1)

1. Configure GitHub MCP Server ⚡

   # Add to workflow frontmatter
   tools:
     github:
       mode: remote
       toolsets: [default]

   This provides secure GitHub API access without exposing api.github.com to the firewall.

2. Review LinkedIn Access 🔍

   • Investigate why research workflow accesses LinkedIn (90 blocks)
   • Consider if this violates LinkedIn's Terms of Service
   • Remove LinkedIn access unless explicitly authorized and necessary

3. Allowlist Critical GitHub Domains ✅

   # Add to workflow frontmatter if GitHub MCP not suitable
   network:
     allowed:
       - "github.com"
       - "raw.githubusercontent.com"

Short-Term Actions (Priority 2)

4. Address Package Registry Blocking 📦

   • Add package registries to allowlist if runtime installation is required:

     network:
       allowed:
         - "registry.npmjs.org"
         - "pypi.org"
         - "files.pythonhosted.org"

   • Alternative: Pre-install dependencies in workflow setup

5. Monitor Denial Rate Threshold 📊

   • Set up alerting if denial rate exceeds 30%
   • Current rate (25.2%) approaching critical threshold
   • Continue monitoring for sustained improvement

Long-Term Actions (Priority 3)

6. Implement Network Access Auditing 🔒

   • Track which workflows request which domains
   • Identify patterns in denied requests
   • Build allowlist based on legitimate access patterns

7. Update Workflow Documentation 📚

   • Document required network access for each workflow
   • Provide examples of proper network configuration
   • Include GitHub MCP server setup guide

8. Security Review 🛡️

   • Investigate firewall-escape workflow's bypass attempts
   • Ensure no workflows are circumventing firewall protections
   • Review access patterns for suspicious behavior
