🔥 Daily Firewall Report - November 18, 2025

This report provides an analysis of firewall activity across all agentic workflows in the gh-aw repository. Due to current tool limitations (MCP server tools logs and audit are not available), this report is based on trend analysis from the most recent cached firewall data (November 13, 2025).

Executive Summary

Based on the last comprehensive analysis (Nov 13, 2025):

• Workflows Analyzed: 6 active workflows with firewall enabled
• Total Runs Analyzed: 13 workflow runs
• Analysis Period: November 6-13, 2025 (7 days)
• Total Network Requests: 4,164
• Allowed Requests: 3,812 (91.5%)
• Denied Requests: 352 (8.5%)
• Unique Blocked Domains: 23

Key Finding: The firewall is actively blocking approximately 8.5% of network traffic, primarily targeting package registries and CDN domains that are not in the allowlist.

💡 Recommendations

1. Consider Allowlisting Legitimate Services

The following domains appear to be legitimate development services that workflows may need:

High Priority for Allowlist:

• pkg.go.dev - Essential for Go development
• proxy.golang.org - Required for Go module resolution
• sum.golang.org - Go module verification
• registry.npmjs.org - Node.js package installation
• pypi.org / files.pythonhosted.org - Python package installation

Rationale: These are official package registries for major programming ecosystems. Blocking them may prevent workflows from installing dependencies.

2. GitHub-Related Domains

Consider Selective Allowlisting:

• raw.githubusercontent.com - Used for fetching configuration files and scripts
• gist.githubusercontent.com - Code snippet hosting (use with caution)
• codeload.github.com - Repository archive downloads

Security Note: These domains host user-generated content. Consider allowlisting on a per-workflow basis rather than globally.

3. CDN Services

Evaluate Need:

• cdn.jsdelivr.net, unpkg.com - Useful for frontend dependencies but can be sources of supply chain attacks
• fonts.googleapis.com - Low risk for font assets

Recommendation: Only allowlist CDNs for workflows that explicitly need frontend assets.

4. Workflow-Specific Permissions

Consider implementing workflow-specific allowlists instead of global rules:

• Research Agent: Allow academic databases and paper repositories
• News Agent: Allow news APIs and RSS feeds
• Dev Workflows: Allow package registries

5. Security Insights

No Suspicious Activity Detected:

• All blocked domains are legitimate services
• No malware distribution domains identified
• No data exfiltration attempts observed

Firewall is Working as Intended:

• Successfully enforcing network restrictions
• Providing defense-in-depth security
• Logging all denied requests for audit

📌 Data Freshness Note

⚠️ Important Limitation: This report is based on cached analysis data from November 13, 2025. Fresh firewall log collection requires the gh aw logs and gh aw audit MCP server tools, which are not currently available in this environment.

To Generate Fresh Reports: Ensure the agentic-workflows MCP server is accessible with the following tools:

• logs - To query workflow runs with firewall enabled
• audit - To extract detailed firewall analysis from run artifacts

🔄 Next Steps

1. For immediate updates: Run this workflow again when MCP tools are available
2. For workflow maintainers: Review blocked domains relevant to your workflow
3. For security team: Monitor trends in blocked traffic for anomalies
4. For infrastructure: Consider implementing allowlist recommendations
