[security-observability] Daily Security Observability Report — 2026-11-11

[github-actions[bot]]

Executive Summary

Across 20 audited runs (of 79 eligible), the firewall allowed 1,736 of 1,737 requests and blocked one. That single block went to an unresolved (unknown) domain. DIFC integrity filtering emitted 129 events across 13 runs. Most of that signal comes from one workflow: Daily Documentation Updater produced 64 events (50%) and its run failed (§43005096362). Two events carried private secrecy tags on code-scanning data, which the filter blocked as designed.

Coverage is partial. Every selected run was created on 2026-11-11 (10:36–15:53 UTC), so this report reflects about one day of activity, not the seven-day window the template describes. See Data Notes.

🔥 Firewall Analysis

Firewall Requests per Run

Traffic is dominated by the 726-request Daily Documentation Updater run. The other 19 runs made 15–127 requests each. Allowed destinations were GitHub and Copilot APIs, telemetry endpoints, Go module proxies, Google Cloud storage, and OpenAI.

Top Blocked Domains

There was one blocked request, from Daily Fact (§43036391442), attributed to (unknown). Nothing indicates a missing allowlist entry, but the missing domain attribution should be checked.

Most Frequently Blocked Domains

Domain	Times Blocked	Workflows	Category
(unknown)	1	Daily Fact	Unattributed

Policy Rule Attribution

📋 Policy: 11 rules, SSL Bump disabled, DLP disabled. Rule hits were zero in every audited run, so rule-level attribution is not informative for this window.

🔒 Firewall Security Recommendations

• No allowlist changes are indicated by the observed traffic.
• Resolve the (unknown) attribution on the single Daily Fact block.

🔒 DIFC Integrity Analysis

Key DIFC Metrics

Metric	Value
Total filtered events	129
Unique tools filtered	9
Unique workflows affected	9
Most common filter reason	Integrity (128 of 129)
Busiest hour (UTC)	10:00 (64 events)

📈 DIFC Events Over Time

All events fall on 2026-11-11. By hour: 10:00 (64), 12:00 (27), 14:00 (27), and 11 across 11:00, 13:00, and 15:00. A single day cannot show a trend, so the spikes reflect burst activity, not a sustained pattern.

🔧 Top Filtered Tools

search_issues accounts for 73 events (57%). It is followed by get_discussion_comments (20), search_pull_requests (19), and get_job_logs (12). The remaining five tools account for 5 events in total.

🏷️ Filter Reasons and Tags

Reason text is integrity for 128 events and secrecy for 1. Integrity tags are none:public (127), unapproved:public (76), and approved:public (1). Two events carry the secrecy tag private: one on a code-scanning alert metadata resource and one on a security alert.

👤 Per-User DIFC Breakdown

Not available. The audit output contains no author_login or author_association fields for these events.

💡 DIFC Tuning Recommendations

1. Daily Documentation Updater (64 events, failed run §43005096362): review its issue-search scope. The filtered events show it retrieving low-integrity issues, so narrowing the query may reduce filtered results.
2. search_issues (57% of events): the same resources recur, for example #76743 and #76700 each appear in several Agent Performance Analyzer events. Consider pre-filtering these queries rather than relying on gateway filtering.
3. Secrecy-tagged events: Code Scanning Fixer (§43024402887, failed) and GitHub MCP Structural Analysis both hit private data. The filter behaved as designed; confirm these workflows do not depend on that data.
4. Audit-tool gaps: author fields are missing from audit output, which blocks the per-user breakdown. The workflow instructions also reference gateway_analysis.filtered_events, but the events are at mcp_tool_usage.filtered_events. Update the workflow to match.

Data Notes

• Coverage: 20 selected, 20 audited, 59 omitted by the cap (79 eligible), 0 failed. Coverage is partial. The firewall dataset has 10 runs: 7 were audited, 1 is this run (excluded by design), and 2 were omitted by the cap (§43052614586, §43049232638).
• Collection limit: the DIFC log collection reported a storage limit, so the collection may be incomplete.
• Warm start: the cached DIFC snapshot is dated 2026-11-11T16:04:45Z and was treated as valid.
• Chart 1 shows per-run bars rather than a 30-day trend, because the data spans a single day.
