🔒 Security Insights

Firewall Configuration

The analyzed workflows use network permission controls to restrict outbound connections from AI agents. This is a security feature that:

• Prevents unauthorized external API calls - Agents can only access approved domains
• Blocks data exfiltration - Limits where sensitive data can be sent
• Reduces attack surface - Restricts potential points of compromise
• Enables audit trails - All network access is logged via Squid proxy

Workflow Configurations Observed

Based on the workflow metadata, the firewall-enabled workflows are using:

• Engine: Copilot/Claude with network restriction features
• Proxy Type: Squid proxy for HTTP/HTTPS traffic filtering
• Log Format: Squid access logs with domain/URL tracking
• Artifact Retention: 28 days (standard GitHub Actions retention)

💡 Recommendations

1. Enable Detailed Log Analysis

Current State: Firewall logs are being collected but not automatically parsed.

Recommendation: Implement automated parsing of Squid access logs to extract:

• Blocked domains (HTTP 403/ERR_ACCESS_DENIED responses)
• Allowed domains (HTTP 200 responses)
• Request patterns and frequencies
• Timestamp analysis for security events

2. Expand Firewall Coverage

Current State: Only 3-4 workflows have firewall features enabled.

Recommendation: Review all agentic workflows and enable firewall features for:

• Workflows processing untrusted user input
• Workflows with web-fetch or web-search tools
• Workflows interacting with external APIs
• High-privilege workflows (contents: write, etc.)

3. Implement Continuous Monitoring

Recommendation: Schedule this firewall report workflow to run:

• Daily - For security-sensitive repositories
• Weekly - For development/testing environments
• On-demand - When investigating security incidents

4. Create Firewall Policy Documentation

Recommendation: Document:

• Which workflows require firewall protection
• Standard allow-lists for common development tools
• Process for requesting domain allow-list additions
• Security review requirements for network permissions

5. Log Retention and Archiving

Current State: Artifacts expire after 28 days (GitHub default).

Recommendation: For compliance or security audit purposes:

• Archive firewall logs to long-term storage
• Implement log aggregation across all workflow runs
• Create searchable log database for incident response

📝 Next Steps

To get more detailed blocked domain analysis:

1. Download Firewall Logs:

   gh run download 18898744073 -n squid-logs-smoke-copilot-firewall
   gh run download 18893010860 -n squid-logs-smoke-copilot-firewall
   gh run download 18881979253 -n squid-logs-firewall-test-agent

2. Parse Squid Access Logs:

   # Extract denied requests
   grep "TCP_DENIED\|ERR_ACCESS_DENIED" access.log
   
   # Extract allowed requests
   grep "TCP.*200" access.log
   
   # Count unique domains
   awk '{print $7}' access.log | sort | uniq -c

3. Analyze Patterns:

   • Look for repeated denial patterns
   • Identify legitimate services being blocked
   • Detect potential data exfiltration attempts
   • Review timing of network access requests

Agentic Q triggered by this discussion comment.

✅ Workflow Updated Successfully

I've created a pull request to enhance the daily-firewall-report workflow to show tables of domains allowed and blocked across all runs.

What Changed

The workflow now includes:

1. 📊 Domain Access Summary Table - A comprehensive table showing ALL domains (both allowed ✅ and blocked 🚫) with:

   • Status (allowed/blocked)
   • Request counts
   • Which workflows accessed them
   • First and last seen timestamps
   • Example URLs

2. 🔍 Detailed Squid Log Parsing - Instructions for:

   • Downloading actual squid-logs-* artifacts from workflow runs
   • Parsing Squid access log format (field-by-field documentation)
   • Extracting domain names, response codes, and timestamps
   • Categorizing as allowed (status 200) vs denied (status 403)

3. 📈 Enhanced Reporting Sections:

   • Top blocked domains table (most frequent first)
   • Per-workflow breakdowns showing both allowed and blocked domains
   • Complete domain lists (alphabetically sorted) with occurrence counts
   • Temporal tracking (first/last seen dates)

4. 💡 Actionable Recommendations based on real access patterns:

   • Legitimate services that should be allowlisted
   • Security concerns from suspicious domains
   • Network permission optimization suggestions

Example Table Format

The report will now include a table like this:

Domain	Status	Count	Workflows	First Seen	Last Seen	Example URL
evil.com	🚫 Blocked	5	dev.firewall, smoke-copilot.firewall	2025-10-28 10:15 UTC	2025-10-29 06:06 UTC	evil.com:443
api.github.com	✅ Allowed	42	dev.firewall, smoke-copilot.firewall	2025-10-28 10:15 UTC	2025-10-29 06:06 UTC	api.github.com:443
pypi.org	✅ Allowed	15	dev.firewall	2025-10-28 10:15 UTC	2025-10-29 06:06 UTC	pypi.org:443

Testing

The next time the workflow runs (daily at 10am UTC or via manual trigger), it will:

1. Download Squid access logs from recent firewall-enabled workflow runs
2. Parse the logs to extract real domain access data
3. Generate comprehensive tables showing exactly which domains were allowed and blocked
4. Create a discussion in the "audits" category with the full report
