[security-observability] Daily Security Observability Report — 2026-10-02

[github-actions[bot]]

Executive Summary

Over the last 7 days there were no blocked firewall requests and no DIFC integrity-filtered events in the sampled runs. Firewall traffic was entirely allowed, and all audited runs reported zero entries in gateway_analysis.filtered_events. Because both datasets were empty, no charts were generated.

Scope caveat: 100 firewall-enabled runs were listed, but per-run audit was only performed on the 8 runs in the DIFC candidate set (7 succeeded; run 36990542652 "Dependabot Dependency Checker" could not be audited because its artifacts were unavailable). The firewall totals below come from those 8 runs' aggregated firewall log, not from all 100 runs.

🔥 Firewall Analysis

Key Firewall Metrics

Metric	Value
Workflows analyzed (audited)	7 of 8 (100 firewall-enabled runs listed)
Total network requests monitored	186
✅ Allowed requests	186
🚫 Blocked requests	0
Block rate	0%
Total unique blocked domains	0

Allowed Domains

Domain	Allowed Requests
api.anthropic.com:443	51
api.githubcopilot.com:443	46
o205451.ingest.us.sentry.io (+:443)	32
api.openai.com:443	28
otlp-gateway-prod-eu-west-2.grafana.net:443	24
ab.chatgpt.com:443	5

No policy violations were observed. All destinations are engine APIs or telemetry endpoints.

🔒 Firewall Security Recommendations

1. No allowlist changes needed based on this window.
2. Coverage gap: extend the audit to all 100 firewall-enabled runs. The current approach only audits runs from the DIFC candidate list.
3. Sentry appears both with and without :443. This is only a normalization difference in the logs.

🔒 DIFC Integrity Analysis

Key DIFC Metrics

Metric	Value
Total filtered events	0
Unique tools filtered	0
Unique workflows affected	0
Most common filter reason	n/a
Busiest day	n/a

Audited workflows (no filtered events): Issue Triage Agent, GitHub MCP Structural Analysis, Dev, Auto-Triage Issues, Daily Assign Issue To User, GitHub Remote MCP Authentication Test, Daily Regression Audit.

💡 DIFC Tuning Recommendations

1. No tuning needed. No integrity or secrecy filtering occurred.
2. Re-check the data source: the candidate runs are "filtered-log" matches, but none contained filtered events. Confirm the selection criteria aren't over-inclusive.
