## RECOMMENDED SECURITY ACTIONS

Risk Score: 50/100 (Moderate)

Recommended Mitigation: Block recommended due to elevated risk score, though context-dependent.

Firewall Rules:

• iptables: `iptables -A INPUT -s 13.212.103.127 -j DROP`
• nftables: `nft add rule inet filter input ip saddr 13.212.103.127 drop`
• nginx: `deny 13.212.103.127;`
• pfSense: `13.212.103.127/32`
• Cloudflare WAF: Block with expression `ip.src eq 13.212.103.127`
• AWS WAF: Add to blocklist as `13.212.103.127/32`

Action Priority: LOW-MEDIUM (consider blocking only if specific threat correlation exists)

---

## ANALYST NOTES

1. Cloud Context: This is a legitimate AWS EC2 instance. Blocking may impact legitimate business operations if the IP is associated with your organization.

2. Geolocation Discrepancy: One probe reported US coordinates (39.83°N, -98.58°W) – this is likely a DNSBL or reputation feed artifact rather than actual geolocation.

3. Recommendation: Review threat correlation before implementing blocking. If no specific threat intelligence correlates, consider allowing with monitoring rather than blanket blocking.
