---

**Recommended Actions**

• Firewall Rules:

- iptables: `iptables -A INPUT -s 177.71.251.172 -j DROP`

- AWS WAF: Block IP with rule `{"Addresses":["177.71.251.172/32"], "Description":"IPDebrief risk 50"}`

• Monitoring: Verify AWS instance activity and access controls, as the IP is associated with cloud infrastructure.

**Conclusion**

This IP is associated with AWS infrastructure and shows no direct malicious indicators. The moderate risk score and clean subnet suggest it may be a legitimate cloud resource. However, the failed ICMP validation and lack of geo-verification warrant further investigation into its network behavior and access policies. SOC teams should monitor for unexpected traffic patterns or deviations from AWS baseline behavior.
