Analysis reviewed 24 signal observations. Key temporal findings include:

• Consistent ASN 16509 attribution across all observations
• Subnet classification maintained as "mostly_clean"
• One threat sibling detected within the /24 neighborhood (54.191.39.0/24)
• No ownership changes recorded
• Threat observation count: 1 (isolated, non-persistent)

The neighborhood (54.191.39.0/24) showed an abuse density of 1 with 1 active sibling. Risk inheritance to the target IP remained low at score 2.

## Relationships Graph

The relationship analysis identified 45 associated entities, primarily:

• DNS associations to the EC2 hostname (repeated mappings)
• Network block relationships to AMAZO-ZPDX8
• Cloud infrastructure connections

These relationships confirm the IP's classification as AWS cloud infrastructure.

## Recommended Actions

Based on the threat profile and risk assessment:

1. Traffic Handling: Allow standard traffic patterns consistent with AWS cloud communication

2. Firewall Rules: No blocking rules recommended; IP represents legitimate infrastructure

3. Monitoring: Continue standard monitoring; no elevated threat indicators present

4. Incident Response: No action required unless unusual behavior patterns emerge

## Conclusion

IP 54.191.39.88 represents a standard AWS cloud compute resource with low risk characteristics. The endpoint shows no evidence of malicious activity, command and control, or data exfiltration patterns. SOC teams may treat this IP as benign infrastructure requiring standard operational monitoring.
