## OPERATIONAL RECOMMENDATIONS

Assessment: The moderate risk score (50) appears to be a generic classification for Microsoft Azure cloud hosting rather than indicating malicious activity. Standard cloud infrastructure typically carries baseline risk scores due to hosting capabilities.

Recommended Actions:

• No blocking recommended without corroborating evidence of malicious use
• Monitor for actual exploit attempts or abuse reports
• Verify any blocking requirements against legitimate cloud service usage
• Standard cloud provider IPs should be evaluated on a per-incident basis

Firewall Rule Status:

• Current system may generate false-positive blocks based on automated risk scoring
• Manual review advised before implementing DROP rules for this IP

---

## CONCLUSION

20.240.137.17/32 represents legitimate Microsoft Azure cloud infrastructure with no evidence of malicious activity. The moderate risk score should be contextualized within standard cloud hosting risk profiles. SOC analysts should evaluate this IP based on actual observed behavior rather than automated risk scoring alone.
