## SECURITY RECOMMENDATIONS

Current Risk Level: Low — No immediate action required.

Firewall Rules

No specific firewall rules recommended due to low-risk profile.

Monitoring Recommendations

1. Monitor Geo Inconsistencies: Investigate probes reporting US-NY origin. May indicate reflection, spoofing, or routing anomalies.

2. DNS Verification: Hostname points to gvt.net.br (Google infrastructure). Verify if this is expected for mobile infrastructure.

3. Baseline Establishment: Continue monitoring for service openings or threat indicator emergence.

Action Thresholds

• Block if: Risk score increases above 50, threat indicators appear, or abuse confidence score exceeds 0.5
• Investigate if: New ports open, SSL certificates appear, or blacklist listings emerge

---

## CONCLUSION

IP 177.17.123.23 is a legitimate mobile carrier endpoint with no active malicious indicators. The primary concern is geolocation inconsistency between probes. SOC teams should maintain awareness but no immediate blocking is warranted. Continue standard monitoring for any risk profile changes.

Classification: LOW RISK — Legitimate Mobile Infrastructure

Action Required: Monitor only
