[security-observability] Daily Security Observability Report — 2026-08-22

[github-actions[bot]]

Executive Summary

Over the last 7 days, all firewall-enabled workflow activity captured in this analysis window occurred on 2026-08-22, spanning 96 completed runs across 25 distinct workflows. Network traffic was overwhelmingly benign: of 4,224 total requests monitored, 98.9% (4,176) were allowed and only 1.1% (48) were blocked, spread across 8 unique domains. The blocking activity concentrated almost entirely in one workflow (Smoke Claude, 32 of 48 blocks), largely tied to Google service endpoints (autofill, accounts, gstatic) that are typical smoke-test artifacts rather than genuine security incidents.

On the DIFC (Data Integrity and Flow Control) side, no integrity-filtered events were found in the last 7 days — the pre-collected filtered-logs.json returned zero runs and the cached snapshot was empty (refreshed at 2026-08-22T16:03:16Z), meaning no tool calls were blocked by the integrity/secrecy filtering system in this window.

No cross-cutting anomalies were detected between the two signals: the workflows with the most firewall blocks (mostly smoke/test workflows exercising real websites) show no correlation with any DIFC filtering activity, since there was none to compare against.

🔥 Firewall Analysis

Key Firewall Metrics

Metric	Value
Workflows analyzed (firewall-enabled)	96
Workflows with firewall data	88
Total network requests monitored	4,224
✅ Allowed requests	4,176
🚫 Blocked requests	48
Block rate	1.1%
Total unique blocked domains	8

📈 Firewall Request Trends

All firewall-enabled runs available for this analysis window fall on a single day (2026-08-22), so the trend chart reflects one data point rather than a multi-day trend. Allowed traffic (4,176 requests) vastly outweighs blocked traffic (48 requests), consistent with a healthy, low-friction firewall posture across the fleet.

Top Blocked Domains

Blocked traffic is concentrated on Google-owned infrastructure domains (content-autofill.googleapis.com, www.google.com, accounts.google.com, android.clients.google.com, www.gstatic.com) almost exclusively from the Smoke Claude workflow, which likely exercises a browser or web-automation tool that attempts outbound calls to Google services not covered by its allowlist. proxy.golang.org appearing once in Smoke Pi suggests a Go module fetch was blocked — worth allowlisting if that workflow legitimately needs Go tooling.

Most Frequently Blocked Domains

Domain	Times Blocked	Workflows	Category
content-autofill.googleapis.com:443	10	Smoke Claude	Google services (browser autofill)
www.google.com:443	8	Smoke Claude	Google services (web)
accounts.google.com:443	6	Smoke Claude	Google services (auth)
android.clients.google.com:443	4	Smoke Claude	Google services (Android)
www.gstatic.com:443	3	Smoke Claude	Google services (static assets)
storage.googleapis.com:443	2	Delight	Google Cloud Storage
proxy.golang.org:443	1	Smoke Pi	Go module proxy
clients2.google.com	1	Smoke Copilot Small	Google services

[Note: Smoke Gemini, Daily Malicious Code Scan Agent, and Agent Container Smoke Test each recorded 1 blocked request, but the specific blocked domain per-workflow was not separately itemized beyond the table above; see per-workflow breakdown below.]

Policy Rule Attribution

📋 No rule-level hit/deny attribution data was reported by the audit tool for any of the 96 runs analyzed (rule_hits and denied_requests were empty across all policy_analysis results). Observed policy configurations ranged from 9–12 rules with SSL Bump and DLP disabled across sampled runs — rule-level attribution instrumentation may not be populated for this workflow generation, so blocked-domain counts above are derived directly from firewall_analysis rather than policy rule hits.

25 workflows in total had firewall telemetry; only 8 recorded any blocked requests. The remaining 17 workflows had zero blocks.

🔒 Firewall Security Recommendations

1. Smoke Claude accounts for two-thirds (32/48) of all blocked requests. Review its network egress allowlist — if it legitimately needs to reach Google account/autofill/static-asset endpoints (e.g., for browser automation testing), add them explicitly rather than leaving them blocked, which can produce noisy logs without security benefit.
2. Smoke Pi's block of proxy.golang.org should be reviewed — if this workflow builds or tests Go code, this domain likely needs to be allowlisted to avoid silent build/test failures.
3. No domains outside well-known Google/Go infrastructure were blocked — there is no evidence of suspicious or exfiltration-style outbound traffic in this window.
4. Continue monitoring: with 88 of 96 runs having firewall telemetry, 8 runs (in-progress/queued or lacking data) should be re-checked in a future report cycle for completeness.

🔒 DIFC Integrity Analysis

No DIFC integrity-filtered events found in the last 7 days. Both the pre-downloaded /tmp/gh-aw/agent/integrity/filtered-logs.json (0 runs) and the cache-memory snapshot (updated_at: 2026-08-22T16:03:16Z, 0 runs) confirm no tool calls were blocked by the Data Integrity and Flow Control system in this window. This indicates either no DIFC-instrumented workflows ran with filtering triggers, or the integrity/secrecy tagging system observed no violations to flag — a positive signal with no action required at this time.
