Daily Firewall Report - 2026-03-03

[github-actions[bot]]

This is the daily firewall analysis report for March 3, 2026, covering network traffic monitoring across all agentic workflows using the Squid proxy firewall. Today's report reflects available data: 30 workflow runs were identified in the past 7 days, all using the Squid firewall (steps.firewall: squid). Due to a missing GitHub token in this workflow run, the audit tool was unable to fetch per-run firewall artifacts directly — available data comes from the cache (last populated March 1) and job log inspection.

Note: For richer future reports, ensure the daily-firewall-report workflow has access to a GITHUB_TOKEN with actions: read permission so the audit tool can download firewall artifact data from each run.

Executive Summary

Report Date: 2026-03-03 | Workflow: Daily Firewall Logs Collector and Reporter (§22636068374)

30 workflow runs were observed across the repository today. All 85 configured agentic workflows use the Squid proxy firewall with a curated domain allowlist. The most recent complete firewall dataset is from 2026-03-01, which showed an extremely low block rate of 0.4% — 1 blocked request out of 248 total. The one observed blocked domain (productionresultssa17.blob.core.windows.net) is an Azure Blob Storage endpoint used for GitHub Actions artifact downloads, which is expected to be blocked by the current allowlist policy.

Top Blocked Domains

Domain	Total Blocks	Category	Workflows
productionresultssa17.blob.core.windows.net	1	Azure Blob Storage (Artifact Downloads)	Multiple

Analysis: The single blocked domain is a Microsoft Azure Blob Storage endpoint (productionresultssa*.blob.core.windows.net). This domain is used by GitHub Actions for artifact upload/download operations. When workflows attempt to download artifacts within the firewall container, this domain is blocked by the Squid proxy since it's not on the allowlist. This is expected behavior — artifact downloads are handled outside the agent container context.

Firewall Activity Trends

Request Patterns

The firewall shows a very healthy traffic profile: 99.6% of all network requests are allowed through the proxy. The low block rate indicates the domain allowlists are well-tuned for typical agentic workflow activity. The primary allowed domains observed include api.github.com, api.githubcopilot.com, raw.githubusercontent.com, and registry.npmjs.org.

Top Blocked Domains

The blocked domain pattern is consistent: Azure Blob Storage endpoints (productionresultssa*.blob.core.windows.net) are the most commonly blocked domains. This is a known false positive — the agent container's Squid proxy correctly blocks requests to domains outside the allowlist, and these artifact storage endpoints are intentionally not whitelisted since agent containers should not download arbitrary artifacts.

Allowed Domains Configuration (From Job Log Inspection — 2026-03-03)

The following domains are configured in the Squid proxy allowlist for typical agentic workflows:

Domain	Purpose	Category
api.github.com	GitHub REST API	Core GitHub
api.githubcopilot.com	GitHub Copilot API	AI/Copilot
api.individual.githubcopilot.com	Copilot Individual API	AI/Copilot
api.business.githubcopilot.com	Copilot Business API	AI/Copilot
api.enterprise.githubcopilot.com	Copilot Enterprise API	AI/Copilot
github.com	GitHub Web	Core GitHub
raw.githubusercontent.com	Raw file content	Core GitHub
registry.npmjs.org	NPM package registry	Package Registry
telemetry.enterprise.githubcopilot.com	Copilot telemetry	Telemetry
host.docker.internal	Docker host networking	Internal

Data Collection Limitation

This report could not retrieve per-run firewall artifact data because the GITHUB_TOKEN environment variable is not set in the daily-firewall-report workflow. The audit tool requires an authenticated GitHub CLI session to download aw_info.json from workflow run artifacts.

View Complete Blocked Domains List

The following blocked domains were identified from available data (2026-03-01 cache):

Domain	Total Blocks	First Seen	Domain Category
productionresultssa17.blob.core.windows.net	1	2026-03-01	Azure Blob Storage

Domain Category Analysis:

• Azure Blob Storage (productionresultssa*.blob.core.windows.net): Microsoft Azure storage endpoints used by GitHub Actions for artifact upload/download. These are used when workflows try to download GitHub Actions run artifacts. Expected to be blocked by current allowlist.

Security Recommendations

✅ What's Working Well

• Very low block rate (0.4%): The Squid proxy is not overly blocking legitimate traffic
• Curated allowlists: Workflows operate with minimal domain access, reducing attack surface
• Consistent monitoring: All 85 workflows use the Squid firewall uniformly

⚠️ Items to Review

1. Fix Firewall Report Authentication: The daily-firewall-report workflow needs a GitHub token with actions: read permission to run the audit tool effectively. Without this, the report cannot access detailed per-run firewall data from artifacts. Consider adding permissions: actions: read to the workflow or ensuring GITHUB_TOKEN is properly passed.

2. Azure Blob Storage Blocking: The domain productionresultssa*.blob.core.windows.net is being blocked. If workflows need to download GitHub Actions artifacts from within the agent container, consider whether this domain pattern should be added to the allowlist. The wildcard pattern *.blob.core.windows.net would cover all Azure Blob Storage endpoints.

3. Expand Historical Data Collection: Currently only 1 data point exists in the cache (2026-03-01). As more runs complete successfully with authentication, the trend analysis will improve. Target: 7-30 days of data for meaningful trend analysis.

🔍 Security Observations

• No suspicious domain access patterns detected
• No unusual traffic spikes observed
• No attempts to access social media, analytics trackers, or unauthorized APIs were detected
• All blocked domains are consistent with expected infrastructure limitations
