[security-observability] Daily Security Observability Report — 2026-05-21

[github-actions[bot]]

Executive Summary

This security observability report analyzes network traffic patterns and data integrity filtering across agentic workflow runs from May 14-21, 2026. Over the 7-day analysis window, 46 firewall-enabled workflow runs generated 1,521 network requests, with the firewall blocking 488 requests (32%) while allowing 1,033 requests (68%) to proceed.

The most significant finding is that all 488 blocked requests are classified as "(unknown)" domains, indicating connection attempts that did not resolve to any specific destination. This suggests potential connection failures, misconfigured network requests, or attempts to reach non-existent endpoints rather than malicious activity. Meanwhile, legitimate AI engine traffic (GitHub Copilot, Anthropic, OpenAI) and development tool traffic (GitHub, Go/Python package repositories, Sentry observability) all passed through the firewall successfully, demonstrating that the current firewall policy is effectively supporting workflow operations while preventing invalid network activity.

Regarding DIFC (Data Integrity and Flow Control) filtering, while the analysis infrastructure successfully processed runs with integrity checking enabled, no integrity-filtered events were recorded in the last 7 days, indicating that all tool calls during this period met the required integrity and secrecy constraints.

🔥 Firewall Analysis

Key Firewall Metrics

Metric	Value
Workflows analyzed (firewall-enabled)	46
Total network requests monitored	1,521
✅ Allowed requests	1,033 (68%)
�� Blocked requests	488 (32%)
Total unique domains (allowed)	11
Total unique domains (blocked)	0 identified

📈 Firewall Request Distribution

The firewall successfully allowed approximately two-thirds of all network requests while blocking one-third. The blocked traffic consists entirely of unresolved or invalid connection attempts, rather than connections to specific blocked domains.

Network Requests by Domain

The chart above shows network request distribution across legitimate domains. GitHub Copilot API (api.githubcopilot.com) accounts for the majority of allowed traffic, followed by Sentry observability telemetry, Anthropic's Claude API, and development infrastructure (GitHub, Go/Python package repositories).

🔒 Firewall Security Recommendations

1. Investigate Unknown Connection Failures: All 488 blocked requests are categorized as "(unknown)" domains, which indicates:

   • Connection attempts that failed DNS resolution
   • Malformed URLs or connection strings in workflow code
   • Timeouts or network errors before domain identification

   Action: Review workflow logs for the most recent firewall-enabled runs to identify the source of these failed connection attempts. Consider adding debug logging to capture full request details before firewall evaluation.

2. Monitor Legitimate Traffic Patterns: The current firewall policy successfully allows all legitimate traffic categories:

   • ✅ AI engine APIs (Copilot, Claude, OpenAI): 741 requests (72% of allowed traffic)
   • ✅ Development infrastructure (GitHub, package repositories): 38 requests (4% of allowed traffic)
   • ✅ Observability telemetry (Sentry): 250 requests (24% of allowed traffic)

   Action: No changes needed to allowlist rules. Current policy is functioning correctly.

3. Reduce Block Rate if Possible: With a 32% block rate, understanding whether these "(unknown)" blocks represent actual threats or benign failures is important:

   • If these are legitimate connection errors, consider improving error handling in workflows
   • If these are malicious probes, the firewall is working as intended

   Action: Correlate "(unknown)" blocks with workflow execution logs to determine root cause and appropriate remediation.

4. Establish Traffic Baselines: With 46 workflows analyzed over 7 days, establish baseline metrics for:

   • Expected block rate per workflow type
   • Normal traffic volume to each legitimate domain
   • Typical unknown/failed connection frequency

   Action: Implement time-series tracking of these metrics in future security observability reports to detect anomalies.

🔒 DIFC Integrity Analysis

DIFC Status

Over the 7-day analysis window, 5 workflow runs were executed with DIFC integrity checking enabled. However, no integrity-filtered events were recorded, meaning all tool calls during these runs met the required integrity and secrecy constraints.

Key DIFC Metrics

Metric	Value
Total runs with DIFC enabled	5
Total filtered events	0
Unique tools filtered	0
Unique workflows affected	0

Analysis

The absence of filtered events indicates one of the following scenarios:

1. All tool calls met integrity requirements — Workflows with DIFC enabled successfully operated within their designated integrity boundaries
2. Limited DIFC adoption — Only 5 runs out of 46 total firewall-enabled runs had DIFC integrity checking enabled (11% adoption rate)
3. No high-integrity workflows triggered — Workflows that require strict integrity controls may not have been triggered during this period

💡 DIFC Recommendations

1. Increase DIFC Adoption: Consider enabling DIFC integrity checking on more workflows to expand coverage and gain better visibility into tool call integrity patterns.

2. Baseline Establishment: Continue monitoring DIFC metrics over the next several reporting periods to establish normal patterns before filtered events occur.

3. Documentation: Ensure workflow authors understand when to enable DIFC integrity checking and what integrity/secrecy tags mean for their workflows.
