[security-observability] Daily Security Observability Report — 2026-08-18

[github-actions[bot]]

Executive Summary

This report covers firewall traffic analysis and Data Integrity/Flow Control (DIFC) integrity-filtering activity across github/gh-aw for the last 7 days. Firewall telemetry was successfully collected from 93 of 100 firewall-enabled workflow runs, showing a very healthy network posture: 4,949 total requests, with only 21 blocked (0.42% block rate). The small set of blocked domains — cdn.playwright.dev, proxy.golang.org, plus a handful of unattributed/malformed log entries — appear to be routine dependency-fetch attempts rather than signs of compromise or malicious activity.

No DIFC integrity-filtered events were found in the last 7 days (the cached snapshot and the fresh log query both returned zero runs), meaning no tool calls were blocked by the integrity/secrecy filtering system during this window. Overall, this is a quiet, low-risk week from both firewall and DIFC signal perspectives, with only minor firewall allowlist tuning opportunities worth noting.

🔥 Firewall Analysis

Key Firewall Metrics

Metric	Value
Workflows analyzed (firewall-enabled)	93
Total network requests monitored	4,949
✅ Allowed requests	4,928
🚫 Blocked requests	21
Block rate	0.42%
Total unique blocked domains	4

📈 Firewall Request Trends

Across the 93 analyzed runs, allowed traffic (4,928 requests) overwhelmingly dominates blocked traffic (21 requests, log scale shown for visibility). No sustained blocking pattern or spike was observed for any single workflow; blocked requests were scattered as single-digit occurrences across a handful of distinct workflows.

Top Blocked Domains

The most frequently blocked entry is an unattributed (unknown) domain (14 occurrences across 7 workflows) likely representing malformed/truncated log entries rather than a real domain — worth root-causing. cdn.playwright.dev (6 hits, one Squad Implement run) and proxy.golang.org (2 hits) are legitimate developer-tooling domains (Playwright browser downloads, Go module proxy) that are plausible allowlist candidates if those workflows need them.

Most Frequently Blocked Domains

Domain	Times Blocked	Workflows	Category
(unknown)	14	Architecture Guardian, CLI Consistency Checker, Daily Credit Limit Test, Daily Go Test Parallelizer, Daily Malicious Code Scan Agent, Issue Triage Agent, Ponytail Reviewer	Unattributed/log-parsing artifact
cdn.playwright.dev:443	6	Squad implement — 53517	Dev tooling (Playwright CDN)
proxy.golang.org:443	2	Matt Pocock Skills Reviewer	Dev tooling (Go module proxy)
and	2	PR Code Quality Reviewer	Malformed log entry (parsing artifact)

Policy Rule Attribution

📋 Policy: 11 rules, SSL Bump disabled, DLP disabled

No per-rule hit counts were reported by the audit tool for any of the 93 analyzed runs (rule-level rule_hits arrays were empty in all firewall policy responses), so detailed rule attribution is not available this cycle.

🔒 Firewall Security Recommendations

1. Root-cause the (unknown) and and log entries — these look like malformed/truncated firewall log lines rather than real domains. Investigate the firewall log parser or log format for the affected workflows (Architecture Guardian, CLI Consistency Checker, Daily Credit Limit Test, Daily Go Test Parallelizer, Daily Malicious Code Scan Agent, Issue Triage Agent, Ponytail Reviewer, PR Code Quality Reviewer) to ensure blocked-request attribution is accurate.
2. Consider allowlisting cdn.playwright.dev:443 for the "Squad implement" workflow family if Playwright browser binary downloads are an expected part of its test/build process.
3. Consider allowlisting proxy.golang.org:443 for "Matt Pocock Skills Reviewer" if it legitimately needs to fetch Go modules.
4. No evidence of malicious or suspicious domains was found — the block rate (0.42%) is very low and consistent with normal allowlist friction rather than an attack pattern.

🔒 DIFC Integrity Analysis

No DIFC integrity-filtered events found in the last 7 days. Both the warm-start cache snapshot (updated_at: 2026-08-18T16:09:04Z, 0 runs) and the fresh filtered-logs.json query returned an empty runs array, so there is no filtering activity to analyze, chart, or tune this cycle.
