Daily Firewall Report - 2026-02-21

[github-actions[bot]]

This report summarizes firewall activity across all agentic workflows in github/gh-aw for the past 7 days. A total of 31 firewall-enabled runs were collected, of which 22 produced actionable firewall data (9 runs failed before generating network traffic or were cancelled). The overall block rate of 47.6% is notable but expected — the majority of blocked requests are unresolved/unknown connections (logged as -) that represent internal container traffic being intercepted by Squid, not actual security threats. Only 2 real external domains were blocked across the entire period.

📊 Key Metrics

Metric	Value
🔁 Workflow runs analyzed	31 (22 with firewall data)
📡 Total network requests monitored	1,415
✅ Allowed requests	741 (52.4%)
🚫 Blocked requests	674 (47.6%)
🌐 Unique blocked domains (real)	2
📅 Period	2026-02-14 → 2026-02-21

Note on the - domain: 667 blocked requests are logged with domain -. This represents HTTP CONNECT tunnel requests where the destination hostname could not be resolved or was blocked at the TCP level before DNS resolution (e.g., internal container-to-container traffic or HTTPS CONNECT to non-whitelisted IPs). This is normal squid proxy behavior and does not indicate malicious activity.

🚫 Top Blocked Domains

Domain	Total Blocks	Workflows Affected	Category
- (unresolved/tunnel)	667	All 12 workflows	Internal/TCP
github.com:443	4	Changeset Generator	Development Services
proxy.golang.org:443	3	Example: Custom Error Patterns	Development Services

📈 Firewall Activity Trends

Request Patterns by Workflow

Anthropic-powered workflows (Instructions Janitor, Documentation Unbloat, Developer Documentation Consolidator) generate the highest volume of requests, each with ~89-112 blocked requests per run — consistent with Claude's API call patterns. Codex-based smoke tests also show elevated block rates (~46-53%) due to Go module proxy and storage requests.

Top Blocked Domains

The two real blocked domains (github.com:443 and proxy.golang.org:443) represent legitimate development services that some workflows need but haven't been explicitly allowlisted.

Alphabetically sorted list of all unique real blocked domains (excluding internal -):

Domain	Total Blocks	Workflows
github.com:443	4	Changeset Generator
proxy.golang.org:443	3	Example: Custom Error Patterns

Note: 667 additional blocked requests were logged with domain - (unresolved/tunnel). This represents blocked TCP connections where hostname was not captured by Squid. It is present in all 12 workflows and is expected behavior for the container networking setup.

🔒 Security Recommendations

1. github.com:443 — Consider Allowlisting

The Changeset Generator workflow blocked 4 requests to github.com:443 across 3 runs. This is a legitimate development service (likely git clone or API calls). Adding github.com to the allowed domains for this workflow would resolve these blocks without any security risk.

Action: Add github.com to the Changeset Generator network configuration, or verify if the GitHub MCP server handles these calls instead of direct HTTP.

2. proxy.golang.org:443 — Consider Allowlisting

The Example: Custom Error Patterns workflow blocked 3 requests to proxy.golang.org:443. This is the official Go module proxy and is a trusted development service. If this workflow performs Go builds, it needs access to download Go modules.

Action: Add proxy.golang.org to the Example: Custom Error Patterns network configuration if Go module downloads are expected.

3. High Block Rate in Anthropic Workflows — Expected

Documentation and janitor workflows (Instructions Janitor, Documentation Unbloat, Developer Documentation Consolidator) show 45-47% block rates. These are all due to the - (unresolved) pattern and not real external domain blocks. No action needed.

4. No Security Threats Detected

No suspicious domains (malware C&C, data exfiltration endpoints, or unauthorized external services) were observed in the blocked domains list. The firewall is working as intended.

The Smoke Test Agent swoops in from the shadows!

"By the power of Claude Sonnet, I have arrived to test these agentic workflows — and the results are... SPECTACULAR!"

POW! All core tests passed! WHAM! PR review tools deployed! ZAP! The smoke-claude workflow stands strong!

And with a dramatic flourish, the agent vanishes back into the action logs...

💨 ...until next time, github/gh-aw!
