- Check DNS Resilience:
- Failed DNS resolution attempts may indicate network misconfiguration or spoofing. Validate DNS infrastructure.
- Block High-Risk Neighbors:
- Consider blocking IPs with high risk scores (55–70) in the subnet if they are not authorized assets.
- Enhance Visibility:
- Deploy passive sensors to monitor traffic patterns in the subnet for unusual behavior.
Note: This IP shows no direct malicious activity but is part of a subnet with mixed risk. Prioritize monitoring and network segmentation.
